Why do so many people have crooked abs?

These are individual characteristics of muscle structure, and this is normal, only Brad Pitt has straight abs on TV)

Because I'm too lazy to pump up

Because the intestines are crooked

some say that it’s pumped up, although I don’t have it: P

and not just abs

it depends on the structure of the body, genetics and also not using a press roller, many people get cut just like this

It depends on a lot of things: for example, maybe his metabolism is like that, or he eats little, or he just doesn’t take care of himself... or he’s been like this since birth....

Human genetics...

asymmetry is normal for a living person

This is the genetic structure. symmetrical abs are generally rare. Nothing wrong with that))

just go and download, nature created it so it should be so

Why are the cubes far apart from each other?

Here, too, everything depends on the tendons. If the bundles are wide and the muscle bellies are small, the gap between the cubes will be large. If it’s the other way around, the cubes are located close to each other. With very short tendons, the athlete has enormous opportunities for hypertrophy: the cubes will protrude very forward.

What to do if your abs are crooked

Imagine that after many months of hard training, a significant reduction in the percentage of subcutaneous fat, you look at your abs and think: “Wait a minute - why are my abs crooked?” If your abs don't look like those of a fitness model, then first, calm down - this is normal. In fact, if you go to a bodybuilding competition, you will notice that a lot of guys and girls have asymmetry in their abs. From this article you will learn what are the three main reasons for this phenomenon and how to fix it.

Genetic factor

The hereditary composition of muscles (attachment point, shape) is almost impossible to change. Also, tendons, which attach muscles to bones or to each other, play a large role in the appearance of the abs. If you have longer tendons, there will be more gaps between the muscles; if you have shorter tendons, there will be fewer.

Because of this, you won't be able to eliminate crooked abs, although you can correct them a little. Some bodybuilders devote years of rigorous training, trying to sculpt the perfect body and change the appearance of certain muscle groups. Undoubtedly, you can increase muscle volume and remove fat, but the shape of the abs is genetically predetermined, and you can’t do anything about it. Therefore, do not torment yourself once again with the question of what to do if your abs are crooked.

Rachiocampsis

Most people have one shoulder and one side of the spine higher than the other. In this situation, the upper and lower back elongate more, so one shoulder is positioned higher, which can lengthen and stretch the corresponding side of the abdominal wall.

Meanwhile, the other side remains shortened, creating that custom look for your cubes. Asymmetry may also indicate undiagnosed scoliosis. In both of these situations, you can improve your condition and correct your crooked abs.

Load asymmetry

Athletes who have played sports that place stress on one side of the body, such as baseball, tennis, and golf, may redefine the appearance of one side of their abs.

In the photo of crooked abs, the muscles of the working side look more voluminous and prominent, while the other side is underused. For this reason, even if your abs are genetically symmetrical, muscle imbalances can cause your six-pack to be unevenly developed.

How to make your abs more symmetrical?

Despite the fact that the shape of the press is determined genetically, with the help of exercises you can correct it to a certain extent. Ultimately, you need to work each side of your abs individually.

The focus should be on anti-rotation exercises, where your spine must resist rotation. You also need movements that stretch your abdominal muscles

The best exercises for symmetrical abs

• One arm plank.
• Side plank.
• Side plank with twists.
• One-way traction in a crossover.
• Reverse crunches.
• Hanging leg raises.

Make sure that as you do these exercises, your shoulders are pulled down and back, and your latissimus dorsi muscles are activated and contracted. If this doesn't happen, one or both sides may become overly elongated, disrupting the positioning of your abs, giving them an asymmetrical appearance. You also need to get rid of stiffness and spasms in your muscles. Releasing this tension can help make your abs look a little more symmetrical, especially if some abs appear to bulge out more than others.

Conclusion

So, it's time to take stock. How to fix crooked abs?

1. If the arrangement of your abs resembles a chessboard, then it's just a matter of genetics and there's really nothing you can do about it.
2. If your abs look uneven, it could be due to fat accumulation in the lower abdomen. Focus on reducing your overall body fat percentage to correct this. If it is an issue of actual abdominal muscle imbalance, use the recommended exercises above.
3. If your abdominal muscles are stronger on one side and weaker on the other, try to distribute the load evenly. You can also do unilateral exercises.

If you notice that your abs are symmetrical, you should be very pleased, since you are part of a very small percentage of the population with good genetics. However, if you have asymmetry, this is not a reason for frustration. Make sure that you have done everything in your power in terms of training and correcting problems with the spine, but genes, alas, cannot be corrected.

How to pump up abs for a man

Looking at the ideal bodies of bodybuilders, it is easy to calculate how many six-pack abs there are. Some have 4 cubes visible above the lower abdomen, others have miniature bulges even in the area of ​​the ribs, and still others have as many as 8 on their stomach.

They were able to achieve such results with a properly designed training program, including:

• selection of exercises for burning fat;
• correct execution technique;
• compliance with the sports regime;
• frequency of classes.

With intense training, the result can be seen within a month, of course, it all depends on the size of the fat layer.

Eccentric press

A conventional eccentric press, equipped with a dispenser that provides automatic dispensing of a portion of the mass required for pressing one plate, and a mechanism with an adjusting device for applying silver paste, as well as a device for removing manufactured tablets.  

The S-10 type eccentric press can be used to perform stripping, punching and bending work. To avoid accidents during operation, the press is turned on by pressing two handles. The machine is driven from a transmission or from an individual electric motor with a power of 1 kW, making 950 rpm.  

The three-ton eccentric press model 661 (Fig. 82, a) has a cast iron frame and consists of three parts: left and right racks, a base and a C-shaped body, rigidly connected to each other. The tilt is necessary for the convenience of removing finished products and waste from the stamp.  

A tabletop small-sized manual eccentric press (Fig. 142) is used for stitching products of complex configurations in tweezer dies, pressing in columns and bushings in small-sized dies and mold parts, punching shaped windows with punches in dies and mold matrices, as well as in tool parts. production.  

Pedal eccentric press of GAZ design: / - pedal; 2 - table; 3 - rod; 4 - spring; 5 - roller; 6 - eccentric; 7 — lever; S - bed; 9 - spring; 10 - traction.  

What is the difference between an eccentric press and a crank press?  

The advantages of eccentric presses include the ability to easily adjust the slider stroke due to the relative rotation of the connecting rod upper head bushing on the shaft eccentric. In crank presses, this possibility is almost always absent due to the fact that the upper head of the connecting rod is connected directly to the journal of the crankshaft.  

The advantages of eccentric presses include the ability to easily adjust the slider stroke due to the relative rotation of the connecting rod upper head bushing on the shaft eccentric. In crank presses, this possibility is almost always absent due to the fact that the upper head of the connecting rod is connected directly to the journal of the crankshaft.  

A significant disadvantage of eccentric presses is the small stroke of the rod. In a press of this design it is 20 mm.  

A significant disadvantage of eccentric presses is the small stroke of the rod.  

The advantages of eccentric presses include the ability to easily regulate the stroke of the slider by turning the bushing of the upper connecting rod head on the eccentric of the shaft. This feature is rare in crank presses, since in most designs the upper head of the connecting rod is connected directly to the journal of the shaft.  

The prisms pressed on an eccentric press were squeezed out of the cells. One worker filled the funnels with gunpowder, the other serviced the press.  

The stamp is installed on an eccentric press. The workpiece strip is fed to the stops with the press slide in the uppermost position. As the slider moves downwards, the clamping bar presses the workpiece, and the upper shaped knife cuts the strip across, simultaneously bending its edges around the mandrel. The mandrel is supported by the force of the pressing cylinder, which exceeds the force required to bend the workpiece around the mandrel.  

how to make your abs even

#1

A flat or sculpted stomach is currently the standard for both men and women

However, it often happens that when working on the abs, different muscles are given different attention. For example, you can often see that a person works more on the rectus muscle, bypassing the oblique and inferior muscles.

#2

If this trouble could not be avoided, you should know how to straighten the press, it is quite possible. This is not a difficult matter, but it will require a lot of time and effort; such an issue cannot be resolved in a few days.

#3

To straighten your abs (you can do this even at home), you just need to not be lazy and know a certain number of exercises. It is recommended to do each of them 20 times in 2-3 approaches.

#4

Lower abs exercises. The lower abdominal muscles will be involved here. Sit on the floor, leaning on your hands and trying not to lean back. Bend your knees, lift and alternately straighten one or the other leg without touching the floor. There is no need to rush or make jerks; smoothness is important.

#5

The next exercise is performed lying on your back. Hands are placed behind the head or holding the buttocks. Raise your legs up without bending, then slowly lower them without touching the floor, repeat 15-20 times.

#6

Another effective exercise is performed using a crossbar. You need to keep your legs together, hanging on the horizontal bar and smoothly lift them to your chest. It would be correct to briefly fix your position at each point, without straightening your legs completely. These three exercises are perfect for working and pumping up your lower abs.

#7

Exercises to work the oblique muscles. The simplest thing is tilting to the side. Hands behind your head, feet shoulder-width apart. Tilts should be made alternately in one direction or the other. Turns to the right and left will be just as effective; the starting position is the same as when bending.

#8

The next exercise is done from a lying position. Bend your legs, put your hands behind your head so that your elbows point in different directions. Next, twists are performed. You need to reach with the elbow of your right hand towards your left knee (ideally, touch it) and vice versa, with your left elbow - towards your right knee.

#9

Upper abs exercises. The simplest and most common is to lie on your back, legs bent at the knees, hands behind your head or extended along your body. Slowly raise the upper body, at the top point it is advisable to fix your position for a few seconds, return to the starting position, repeat 20-30 times in 1 approach.

Correct abdominal exercises

Trying to strengthen their sides or create a thin waist, many begin to perform distortions in different directions, without even thinking about the advisability of the exercise in a particular case. When the job has already been done and the mistake described above has been made, or nature is to blame for everything, then you need to be patient.

Experienced specialists recommend taking the problem seriously and explain how to straighten the press if it is crooked. Therefore, the first thing you need to do is stand against the wall and move away in the same position with some weight on your head, maintaining your balance and straightening your posture. Further in everyday life, while sitting at your workplace, you need to keep your back straight and avoid curvature.

Common abdominal exercises include:

- raising the body from a lying position;

- perform simultaneous leg lifts while hanging on the horizontal bar;

- raise straightened legs from a lying position.

Additionally, physical therapy to strengthen the back muscles can help.

Press rating of the best exercises

Below are the results of a comparative study of popular abdominal exercises. It should be noted that although the primary goal was to determine the best exercises for both the rectus abdominis muscles and the lateral abdominal muscles, in the end it turned out that only extremely well-trained people can isolate a certain area - this is almost inaccessible to beginners. That is why abdominal training for beginners has its own characteristics.

The best exercises for the rectus abdominis muscles

Exercises for the lateral abdominal muscles

Anatomy lessons

As Astrid Swan, a personal trainer at the American National Academy of Sports Medicine (NASM), explains, the so-called abs are actually a single rectus abdominis muscle that runs from top to bottom, from the bottom of the ribs to the pubic bone. This muscle is crossed by three tendon bridges, two of which are located above the navel, and the third tendon is located approximately at its level. Thus, four isolated areas are formed on the rectus abdominis muscle, which, under the influence of training and a certain diet, develop and begin to protrude above the tendons, visually appearing in the form of those long-awaited abs. Thus, a person normally has eight abs that can be “pumped up.” However, as professional trainers explain, with regular training for six months, the six upper “cubes” of the press are developed quite effectively, but only super-persistent applicants can make the two lower “cubes” appear. The problem is that in the upper part of the abs there is much more muscle tissue concentrated, which is trained during exercise, and downward the muscle tissue becomes thinner, remaining in its original state much longer. In addition, in some cases, no amount of training will help pump up abs of more than six, and sometimes even four, due to individual structural features, in which the number of tendons crossing the rectus abdominis muscle may be less than the average norm.

Advantages of a permanent connection

Proper installation of press fittings provides high-quality permanent connections. Their main advantages can be considered:

• High strength. In the docking areas, the permissible operating pressure can reach 10 atmospheres.
• Long service life, during which the characteristics of the unit do not change. The manufacturer promises a 50-year service life of the part, provided it is installed correctly.
• The connections do not require monitoring or maintenance. Thanks to this, they can be successfully used when laying hidden pipelines. They have proven themselves well when pouring concrete.
• The parts do not respond to the linear expansion of pipes that occurs when the temperature of the liquid changes. This makes it possible to install them in heating and hot water supply systems.
• Installation of press fittings is very quick and easy. To implement it, you do not need specific skills and knowledge, which makes it accessible even to a beginner. The only special tools you will need are crimping pliers.
• The use of parts reduces pipe consumption and the amount of necessary fittings, which ultimately significantly reduces the cost of pipeline installation.

The long service life of press fittings is comparable to the service life of pipelines. This is due to the high corrosion resistance and excellent performance characteristics of the parts. The scope of application of the elements is quite wide. They are used: in hot water supply systems; in pipelines carrying cold water; in heating systems where hot coolant circulates under high pressure.

A wide range of press fittings allows you to make pipelines of a wide variety of configurations and reliably connect pipes from various materials

Strength training of the abdominal muscles does NOT burn fat in the abdomen and waist.

For some reason, the spring snowdrops that come to the gym, as Zhigan sings “pump up”, pick up magic programs for removing belly fat from VKontakte communities and storm the crunching machines.

We will not get tired of repeating every week - burning fat in any specific place is IMPOSSIBLE. There are no exercises or techniques (other than liposuction) to remove fat from just the belly or waist. Here's why in detail.

In this regard, barbell squats will be much more effective than attacking abdominal machines.

Secrets of proper installation of such parts

Installation of parts is very quick and quite simple. To do this, you will need a special tool, without which crimping the fitting is impossible.

How to choose press pliers?

Press pliers for fittings are a device designed for installing a part onto a pipe. Manual models and more complex hydraulic ones are available. For independent work, the first option is quite suitable, since it is the easiest to use and cheapest. And the quality of connections made with its help is not inferior to those in the process of which a professional hydraulic tool was used.

When purchasing equipment, you need to consider that it is designed to work with a certain pipe diameter. There are models equipped with special liners that make it possible to work alternately with pipes of several diameters. In addition, improved variations of the instrument can be found on sale. They have a special marking:

• OPS - the device increases the forces applied to it by using step-type clamps.
• APC – during the process, automatic control of its quality is carried out. The press will not open until crimping is completed successfully.

APS - the device independently distributes the force that is applied to it, depending on the size of the fitting.

Crimping pliers are a tool necessary for installing fittings. Manual and hydraulic models of special equipment are available

What to look for when purchasing connectors

The reliability of the connection largely depends on the quality of the parts.

When purchasing press fittings, experts advise paying attention to the following points:

• Quality of markings on the case. Companies that produce quality parts do not use cheap molds. All symbols on the fitting body are printed very clearly.
• Part weight. To produce high-quality products, brass is used, which is quite heavy. It is better to avoid fittings that are too light.
• Appearance of the element. Low-quality parts are made of thin metal that looks like aluminum. It is not able to provide a quality connection.

You should not skimp on fittings and try to buy them “cheaply” at a dubious retail outlet. In this case, there is a high probability of subsequent reworking of the entire pipeline.

Installation secrets from specialists

We begin work by cutting the pipes. We measure the required length and cut the element strictly perpendicularly. It is best to use a special tool for these purposes - a pipe cutter. The next stage is processing the end of the pipe. We insert a gauge inside the part to correct the slight ovality that inevitably forms during cutting. We remove the internal chamfer using a chamfer remover. If it is not available, you can perform this operation with an ordinary sharp knife, and then clean the surface with emery cloth.

At the end of the work, we put the press fitting on the pipe, controlling the tightness of its fit through a special hole. There are models in which the ferrule is not secured to the fitting. To install them, the following operations are performed. We put the crimp coupling on the pipe. Inside the element we insert a fitting on which the o-rings are attached. To protect the structure from electrocorrosion, we install a dielectric gasket at the contact area between the metal connecting part and the metal-plastic pipe.

To crimp any model of press fitting, we use a tool suitable for the diameter. We grab the sleeve with the clamp of the press pliers and bring their handles together until they stop. After removing the tool, two uniform annular strips should remain on the fitting, and the metal should be bent in an arc. Crimping can only be done once; there should be no repeated operations. This leads to damage to the connection.

Installation of press fittings for metal-plastic pipes takes place in four main stages, which are presented in the figure.

Press fittings for metal-plastic provide a very strong, durable connection. Their wide range allows for the production of pipelines of a wide variety of configurations. In addition, they are very easy to install. Even a beginner can install press fittings. This requires patience, accuracy and, of course, careful study of the instructions. The result of your efforts will definitely please you with a reliable pipeline made by yourself.

Several features of statics for the abdomen in men and women

When starting static exercises for the abdomen, it is important to know the features of such exercises in order to perform them correctly and not harm your health.

1. For patients with heart problems or vascular diseases, reduce the load. It is advisable that the training course be selected by a specialist. The same applies to those who are trying to lose weight.
2. A good addition to statics are exercises that will help improve body flexibility and abdominal firmness. If you want to regulate muscle volume and body contour, you can use dynamic exercises.
3. Statics can be performed in the form of circuit training.
4. Static training can be done at home without using additional equipment or devices.
5. The achieved result depends on the load on the abdominal muscles. This is especially true for losing weight. To reduce your waist size and improve muscle tone, it is enough to do half-hearted training. Training at full capacity will help make your abdominal muscles strong and voluminous.
6. During training, it is important not to overdo the load on the body. This can lead to problems with the heart and blood vessels, and impaired blood flow.
7. Tasks can be selected depending on your training experience and muscle strength.
8. After training your abdomen, it is better to do muscle stretching exercises and breathing exercises.

Errors during stamping.

If errors when installing a stamp on a press arise due to negligence or low qualifications of the operator, then the errors of the stamper are mainly associated with the monotony of the work, and as a result, loss of attentiveness. I think that there is no point in punishing a stamper if the same mistake is made periodically, you need to try putting him on stamping another part, or part ways. The only way to try to reduce the likelihood of a die breaking is to assign the stamper to different operations during the shift, and organize a mandatory rest every hour for 10 minutes.

So, description of the errors:

1. When stamping from a strip or tape, the stamper did not have time to advance the strip or tape all the way, and his foot pressed the pedal. The most common mistake. As a result, small-diameter punches, on one side, crashed into the metal of the strip, and on the other, partially fell into a previously punched hole or window. With this option, a lateral force is created, which leads to breakage or clogging of the punch, clogging a hole in the matrix. For punches with large diameters and cross-sections relative to the thickness of the metal being stamped, this is not so critical, but it is undesirable.

2. Stamping on a bending, drawing, or other stamp. When manually laying piece blanks, the stamper accidentally put two blanks into the die instead of one. This can cause the die to rupture, the ejector and punch to collapse, or the press ram to jam. The problem can be partially avoided by delivering the cut blanks for manual laying mixed, and, under no circumstances, in sticky packs. Sometimes, it is possible to provide for a limitation on the stacking height in the design of the stamp.

3. Often, when a strip gets stuck in a sequential die with a movable spring-loaded puller, the stamper uses a screwdriver to try to free the strip from sticking without removing his foot from the pedal. The foot, by inertia, presses the pedal.. The consequences are very different.. Provide the worker with copper wire with a diameter of 3 mm, this will reduce the severity of the consequences of the error.

4. When manually laying the workpieces, the stamper switched the clutch activation from two-handed push-button to foot-operated. He did this because he had a deal and it was faster to work this way. As a result, if your hands get into the working area of ​​the stamp and you press the pedal due to inertia, injuries with the most severe consequences are possible. Block the ability to switch from two-handed to foot mode without the participation of an installer. Guarding the die working area with shields can help. The presses are still in use, without the ability to turn them on with two buttons. It is unacceptable to stamp parts with manual laying on them if you have access to the working area by hand.

5. There is another error made by the stamper, similar to the operator’s mistake with blocking the failure holes, when the stamp is placed on the press correctly, the failure windows and holes are not blocked, but the hole in the bottom plate of the press is smaller than required for normal failure of parts under the press. The installer, in this case, inserts between the gaskets under the bottom plate of the die a piece of strip onto which the parts and waste will fall. The stamper, after stamping a certain number of parts, must remove them from under the stamp using this piece of strip, but he forgot to do this and continued stamping. Parts and waste accumulate in the die, which leads to its rupture, or to breakage of the punches. This can also lead to jamming of the press.

I ask you to take the above seriously, because all the cases are taken from practice and have happened repeatedly.

Benefits of statistical abdominal exercises

Why do many athletes and others choose only static exercises to correct their abdominal muscles?

1. The muscles and ligaments of the abdomen are strengthened and developed. The entire exercise is suitable for both men and women.
2. When doing statistical exercises, muscles almost do not increase in volume, but their strength increases. Thus, attention is paid to the strength factor of the muscles, which is especially important for men. At the same time, active fat burning occurs in parallel.
3. The workouts are simple and accessible. No expensive equipment or special training equipment is required.
4. Statistical abdominal exercises allow you to acquire the ideal body. Especially if you combine them with other tasks.
5. You can train without interrupting your main activity: watching a movie, reading a book, cooking, working. Especially if you repeat some actions daily.
6. It takes little time: a few minutes are enough for one approach.
7. Muscle endurance increases and willpower appears. Such training is also used for weight loss.

Why Abs Are Uneven Gravity Sport

You worked on your abs for a long time and went on a diet, but when the cubes appeared from under the fat layer, it turned out that they did not at all look like the ideal six pack: there are only four of them, not six, they are located in a checkerboard pattern or at an angle. You worked on your abs for a long time and went on a diet, but when the cubes appeared from under the fat layer, it turned out that they did not at all look like the ideal six pack: there are only four of them, not six, they are located in a checkerboard pattern or at an angle. We find out why abs aren't always straight and symmetrical and whether this affects muscle strength.

I pumped up my abs, but my abs are kind of crooked. Why?

The anterior surface of the rectus abdominis muscle is crossed by three or four tendon bridges, due to which the muscle takes the shape of cubes.

In some people, these bridges are slightly shifted or staggered, and as the muscle increases in size, this becomes noticeable.

Why are they different?

This is a genetically determined feature, like eye color or hair structure. Moreover, genetics determines not only the location of the jumpers, but also their number. So, some people will have only four abs, others six, and some even eight.

Does this somehow affect performance?

No. The location and number of tendon bridges do not affect the strength of the muscle, so you can safely engage in strength sports - a different form of abs will not hurt you at all. However, genetics can affect how defined your abs look.

That is, someone can not work out at all, but their abs will be sculpted?

Not certainly in that way. Some people have naturally thicker abdominal muscles. Muscles with this structure will look more prominent, especially if a person has a low percentage of body fat. However, it is impossible to get clear abs without training.

Why are some people's cubes so far apart?

It's all about the tendons that attach the muscles to the bones. If you have long tendons and short muscle bellies, the distance between the cubes will be greater, if on the contrary - less. In people with short tendons, the greater muscle area increases the potential for hypertrophy.

Is there any way to fix asymmetrical abs? Maybe there are special exercises?

No amount of exercise will help you change the genetically determined structure of muscles and tendons. But there's nothing wrong with that. Many bodybuilders and athletes around the world have this type of abs, and this does not stop them from doing what they love, looking great and winning competitions.

Why did the cubes appear only in the upper abdomen?

There may be two reasons:

Hide ad

1. Too thick fold of subcutaneous fat that covers the lower part of the abs.
2. Genetically determined form of abs.

Subcutaneous fat content can be determined using a test. If he shows that the thickness of the fold on the abdomen is about 10 mm, for the sake of the long-awaited cubes you will have to undergo drying. If there is almost no fat in the lower abdomen, you will not be able to gain cubes due to the shape of your abs.
