Sledgehammer training to increase strength

Initially, the sledgehammer was conceived as a blacksmith's tool, but then became widespread in construction, machine repair, and plumbing. The large mass of the striker, which gains force as it swings, allows for powerful strikes without the use of electrical or pneumatic energy. Sledgehammers are divided by weight, with models ranging from 1 to 8 kg. We have created a rating of the best sledgehammers for forging, tire fitting, straightening sheet blanks, driving fasteners, breaking masonry and crushing materials, which will help you navigate the features of the tool and choose the right one.

The benefits of training with a sledgehammer

By hitting a tire with a sledgehammer, you develop core strength endurance, coordination, and explosiveness. There is also a complex load on almost all large muscle groups of the body, due to which your muscles will gradually grow.

The calorie consumption while hitting the tire is sky-high. It is several times higher than the consumption when performing a classic cardio exercise, such as jogging or an exercise bike, which leads to more intense fat burning, excess weight loss and improved relief.

After a few weeks of regular training with a sledgehammer, you will notice that the impact force has increased significantly, and any throws from the rack are much sharper and faster. This occurs due to the coordinated work of the muscles of the back, arms, shoulders and legs, which is what fighting skills are made of.

Hitting the tire can be done with either a sledgehammer or a heavy hammer. Of course, in both cases you need to hit the tire with a longer part so that there is no strong uncontrolled kickback.

Sledgehammer in detail

Among the diversity of the modern market, three main types of this percussion instrument can be distinguished, which correspond to GOST 11402-75 or GOST 11401-75

• The sledgehammer is blunt-nosed, weighing from 2 to 16 kilograms.
• A sharp-nosed transverse sledgehammer weighing from 3 to 8 kilograms.
• Pointed longitudinal sledgehammer from 3 to 8 kilograms.

In the manufacture of the striker, durable steel is used, namely grades 40, 45, 50 and U7. These are unalloyed types of steel intended for the manufacture of tools. A distinctive feature of a hammer made of such steel is the process of its manufacture. The firing pin is not made by casting, but is forged using a forge hammer. This allows you to achieve high strength of the metal.

The place for attaching the handle is made in the form of two cone-shaped holes, the diameter of which narrows towards the center of the sledgehammer. In cross-section it resembles an hourglass. This method of making a hole ensures that the hammer is securely attached to the handle.

Wood is most often used to make a handle or handle. This allows you to soften the recoil force of impacts. Less commonly, the handle is made of metal, plastic or hard rubber alloy. The heaviest load during an impact occurs where the handle is attached, so it is difficult for metal or plastic to cope with such a load.

Today, high-tech plastic or fiberglass, which is based on polyester resins, is often used to make a sledgehammer handle. To soften the recoil force, handles made of such materials are covered with rubber.

Execution technique

Despite the fact that, at first glance, the exercise seems technically elementary, there are a number of rules regarding the technique of performing the exercise with a sledgehammer that you should pay attention to.

1. Grasp the end of the sledgehammer and stand about half a meter from the tire. Hold the handle firmly so that it does not slip out of your hands. Keep your feet parallel to each other, your back straight. Your position must be stable.
2. Take a wide swing, making a circular motion with the sledgehammer over your right shoulder. The left palm is located closer to the end of the hammer. After each repetition you need to change the position of your hands. There is nothing complicated about this, after the first normal approach it will happen automatically. This phase of the movement should be done with minimal effort, you don’t need to put much effort into lifting the sledgehammer, otherwise you will quickly get tired.
3. You need to swing not only with your arms, but with your whole body; the sledgehammer should fly up as quickly as possible.
4. When the hammer is perpendicular to the floor, there will be a slight dead center. At this point, you need to stop swinging and relax your arms and shoulders. It is necessary to lower the sledgehammer down as quickly as possible to make a powerful blow. To do this, we lean forward sharply and help ourselves with the gluteal muscles. Most of all, it resembles chopping wood. The blow should occur while exhaling.
5. Immediately after you hit the tire, begin to straighten your lower back, otherwise the sledgehammer may fly straight into your forehead. The sledgehammer should travel most of the upward distance by inertia. Your task is to intercept it at the moment when it is located approximately at waist level, and change the side of the swing. Alternate between the right and left sides on each rep.

This is not the only option for performing the exercise. Depending on the goals, the technique of performing the exercise may vary. For example, to increase the functionality of the exercise, boxers also change their stance with each repetition, placing their right or left leg forward. This option puts more strain on the leg muscles, since they bear all the support.

You can also hit the tire by swinging from behind your head. This way the blow will be no less powerful, but for unprepared athletes this will quickly tire the lower back.

You can strike by holding the sledgehammer with one hand and using the other to maintain balance.

Types of sledgehammer

The choice is made based on the type of work to be done with this tool. This tool differs not only in the weight of the striker, but also in its shape. There are several forms:

• cross striker;
• sharp-nosed longitudinal sledgehammer;
• sledge hammer;
• blunt-nosed sledgehammer.

The cross-head, sledgehammer and sharp-nosed sledgehammer resemble an ordinary hammer in appearance, but are somewhat heavier than their younger brother. A sharp-nosed sledgehammer and a cross-head sledgehammer will weigh 3-8 kg. A sledgehammer weighs 1-2 kg. A blunt-nosed sledgehammer is the heaviest and most powerful representative among all of them. Striker weight 5-16 kg.

Recommendations for performing the exercise

To get the most out of your CrossFit or MMA training with sledgehammer and tire exercises, it is recommended to follow these simple tips:

1. Perform two to four sets of tire sledgehammer hits per workout. Time under load is important here. Two to two and a half minutes of continuous intensive work is the indicator you should strive for. During this time, a trained athlete will have time to make at least a hundred powerful blows.
2. Monitor your pulse. This exercise greatly relieves the psyche and relieves stress. With its help, you can easily get rid of excess negativity from your head, but sometimes it can be difficult to stop. If after approaching you start to tingle in your temples or in the back of your head, this is not normal. In this case, the intensity should be reduced slightly.
3. Don't round your back when hitting. Even though a sledgehammer usually weighs about 10 kg, the risk of spinal injury is quite high due to the explosive manner of execution.
4. Be sure to warm up before performing this exercise. It is performed in an explosive manner, which means that the risk of some kind of damage is always present. A couple of sets of pull-ups, push-ups, hyperextensions, joint exercises and a little cardio are what you need.
5. Watch your breathing. The blow should occur while exhaling, the swing with a sledgehammer should occur while inhaling. Not the other way around. If you lose your breathing pace, it is better to take a short break and start over. Improper breathing will result in much less oxygen entering the body, muscles will quickly get tired, and blood pressure will also rise.
6. To experience the full benefits of this exercise, it is recommended to do it at least three times a week. This is a great cardio option after strength training. A 10-minute series of tire hits with short rest intervals will replace the monotonous 40 minutes of walking on a treadmill.

The best sledgehammers weighing more than 10 kg

The heaviest sledgehammers allow you to quickly destroy a wall, forge metal, or drive a post into the ground. Only for work you will need serious physical training. One model was recognized as the best in the super-heavy category.

TOPEX 02A511

Rating: 4.9

The best tool for forging and dismantling operations is the TOPEX 02A511 sledge hammer. The Polish development weighs 11.05 kg and has enormous impact energy. The heavy head with a combined striker weighing 10 kg is complemented by a wooden handle 989 mm long. The wood is protected from moisture and dirt by a varnish coating. Experts highly appreciated the versatility of the model; thanks to the combined striker, it is possible to expand the scope of application of the sledgehammer. The manufacturer securely fixed the handle in the head, using an additional adhesive composition.

In the category of super-heavy percussion tools, it is difficult to find a worthy competitor to the TOPEX 02A511 sledgehammer. Users in reviews call it the most powerful and reliable, talking about the scale of the work done.

Advantages

• heavy durable head;
• reliable connection of the head with the handle;
• protective varnish coating;
• high impact energy.

What exercises should you alternate with using a sledgehammer?

It is best to alternate an exercise such as hitting a tire with a sledgehammer with those that have similar functions, that is, they make the torso muscles stronger and more resilient. Ideal for this are horizontal rope spins, handstand push-ups, rope climbs, pull-ups, burpees, barbell thrusters, etc.

If your goal is superhuman endurance, then raise the bar higher. Combine tire kicks with double jump ropes, machine rowing, and muscle-ups on the rings.

An option for real sports maniacs - immediately after you finish hitting the tire with a sledgehammer, move on to flipping the tire. It is best to do this outdoors so as not to be confined by the walls of the gym.

Of course, the tire must be impressive. A spare tire from a car lying on the balcony will not work here.

You can easily find the necessary equipment at a tire shop. For training, an old tire from KamAZ or BelAZ would be an ideal option.

Dismantling, working with reinforcement, hammering fasteners, crumbling and crushing stones, straightening and other heavy manual work cannot be done without the use of a metal sledgehammer. A reliable tool allows you to perform all these tasks as easily and comfortably as possible. Only through the use of such a seemingly simple hand tool will it be possible to achieve maximum productivity and efficiency.

Purpose of the sledgehammer

The sledgehammer is one of the ancient construction tools. Various primitive hammers have been known for a very long time and have survived to this day only in a refined form. One of the ancient varieties of this tool is the sledgehammer, which is still widely used today to perform rough operations.

For example, a sledgehammer can be used when destroying a block of stone or concrete, when hammering massive and heavy metal elements, and when carrying out other similar work. The very name of the sledgehammer seems to hint at the use of this tool in blacksmithing. The date of birth, accordingly, can be attributed, at a minimum, to the Bronze Age. The striker of this instrument was a stone, and the handle was a human hand.

However, it was the invention of the lever that changed the appearance of the sledgehammer: they began to attach a wooden stick to the stone. The joining method chosen by our ancestors anticipated the way the handle is attached in our time. But there was another method: they chose a stone with a hole that would be suitable in weight and size for the striker. And then this stone was placed on a tree branch and waited until the branch grew and was securely fixed in the head of the sledgehammer.

Thus, a tool has survived to this day that performs many jobs. Despite global computerization, the use of robots in industry and worldwide progress, nothing can yet replace the sledgehammer. A construction sledgehammer (two-handed hammer) is a hand-held impact tool that is designed for work that requires the greatest impact force. The main area of ​​application for sledgehammers is free forging using a forging tool.

It also involves delivering strong blows during the installation and dismantling of various communications, metal processing, driving staples, pins, wedges and thick nails into massive logs, knocking out various stuck fasteners, breaking concrete products, bricks and stones when destroying small buildings. It is very convenient to carry out these works when using a sledgehammer with a striker that has a serrated surface.

The sledgehammer is also intended for driving wedges, stakes, piles and poles into the ground; it can be used in construction work, beating tires when dismantling wheels and straightening during car body repairs, straightening metal sheets and blanks, crushing stones into crushed stone (although this method is a bit became obsolete after more productive stone crushers were introduced into quarries). It is also common to use a sledgehammer by cupola workers when knocking castings out of flasks and beating the gating system away from castings.

Sledgehammer design

The design of the sledgehammer is effective and simple. It consists of a striker and a handle. A sledgehammer is constructed to some extent similar to an ordinary hammer, but at the same time has an increased mass of the striker (usually more than 5 kilograms), which is made in the form of a parallelepiped, and an elongated and thick handle on average up to 70-90 centimeters. The weight of the striker, depending on the specification of use of the sledgehammer, can even reach up to 16 kilograms, and the length of the sledgehammer handle can be up to 120 centimeters.

The handle, according to the drawing of the sledgehammer, thickens towards the striker (the handle of the hammer tapers towards the striker) and does not wedge in it. This is also done so that if the sledgehammer misses, it can fly out of the hand and not drag the worker down with it. Due to these differences, a sledgehammer is able to deliver more powerful blows to the surface being treated.

The sledge hammer head is the center of gravity during operation and provides the main shock loads. The handle plays the role of a lever, and in some cases it can be short: when you plan to work in limited space, it is better to choose a sledgehammer with a short handle.

Unlike a hammer, a sledgehammer has a number of advantages: you can hammer in any nail with one blow, provided it hits the target area exactly. Plus, you have the choice of the right tool to solve your problem. If impact force is important to you, you should choose a tool with a larger striker mass and a long handle, which also increases the impact leverage. The smaller the striker has mass, the more accurately you can strike, and the work process will not require much effort.

Types of sledgehammer

Construction sledgehammers differ in length, type and material of the handle, weight, shape, type of hardening and grade of metal of the striker. A real sledgehammer has a handle that is made of shock-absorbing material - wood, fiberglass or composite plastic. Wooden handles should also be made from hardwoods such as pear, dogwood, and acacia.

Typically, the grip area of ​​the handle is covered with a rubber-based material. This is necessary to partially remove vibration and reduce the sliding of hands along the handle. But sledgehammers with a metal handle give “recoil” to the body and hands when working, so working with such a tool is not safe and comfortable due to harm to the musculoskeletal system; it is better to choose a sledgehammer with a wooden handle. The handle can be straight or anatomical in shape.

Since sledgehammer strikers experience high dynamic loads during operation, they are usually made of hard steel grades that have a high carbon content (close to 1%) - the element responsible for hardness. Such steels are called carbon tool steels and are marked U12A, U10, U7 and U7A. Working surfaces are necessarily hardened to a depth of 30 millimeters to a hardness of HRC 32.5.

In some cases, the sledgehammer head weighs up to 15 kg. The inner part of the metal striker in the most advanced models is filled with steel balls. This makes it possible to prevent the sledgehammer from being thrown back after an impact, as does its handle, which is thicker towards the striker. Currently, the appearance of the sledgehammer has also changed. This instrument is available in a variety of colors using modern high-tech materials.

Based on the manufacturing method, there are two types of sledgehammers - forged and cast. Structurally, sledgehammers are divided into certain types: transverse sharp-nosed, which weigh 3-8 kilograms, longitudinal sharp-nosed, which have a similar weight, and blunt-nosed, weighing from 2 to 16 kilograms. You can also make any of these sledgehammers yourself.

Prices for sledgehammers are determined by two factors: the weight of the striker and the steel from which the striker is made. The higher quality the steel used, from which the striker is cast, the more expensive the sledgehammer will be. The heavier the tool, the higher its price will be. In addition, the cost of the sledgehammer also includes the price of the handle.

Making the striker

If you do heavy work and deal heavy blows, you cannot do without a large hammer or sledgehammer. First of all, you need to start creating the tool’s striker. For the manufacture of sledgehammers, it is customary to use alloy and high-carbon steels, which operate under shock loads and high temperatures.

The carbon content in this material is about 0.6 - 2%. Nickel, which is present in such steel, can increase the strength of the tool, chromium - wear resistance and hardness. Manganese is needed to resist impact and abrasion and reduce the harmful effects of sulfur. Silicon increases elasticity and strength.

For the manufacture of sledgehammers, steels 45, 50, 40X are usually used. Grade 40X, for example, means that the steel contains 0.4% carbon and approximately 1.5% chromium. If you couldn’t get hold of one of these grades of steel, don’t be upset. Go to some auto repair shop and try to find an axle shaft from a truck. From one such axle shaft you can make many different tools.

Take a workpiece weighing about 2 kilograms and forge a parallelepiped from it. In the center of one side face you need to sew a through hole, which has a diameter of 20-25 millimeters. After this procedure, the side planes of the workpiece will be deformed. They need to be forged in such a way that the workpiece takes the shape of a regular parallelepiped, and the round hole turns into an oval one.

After this, you need to calibrate the hole to the size and shape that matches the wooden handle. This must be done using a gauge, which is a metal oval rod 150-200 millimeters long with a slight taper along its length. The gauge should first be forged from 40X carbon steel, hardened and ground.

Remember that the lower section of this caliber should be smaller than the cross-section of the hole that is stitched in the workpiece so that the caliber fits two-thirds into it, and the upper section should be slightly larger than the wooden handle. The gauge needs to be hammered into the hole on one side to a certain size, then on the other. To avoid deformation of the side faces, you need to forge the workpiece from the sides, re-hammer the gauge on one side, forge the workpiece without removing the gauge from the sides and upset it from the ends so that it gets the correct shape.

After this, you need to knock out the gauge and repeat the entire operation on the other side of the hole. You should end up with a correctly shaped workpiece with a hole that has a double cone to create a reliable connection to the handle using a wedge. Using a grinder or file, file the surface of the striker and sand it with sandpaper.

The forged striker should be hardened. To do this, heat it in a forge until a bright red glow is obtained, corresponding to approximately 850 degrees, then cool in cold water. After hardening, the sledgehammer becomes hard but brittle. In order for the steel to become hard and gain toughness, it is recommended to temper it.

Sand the surface of the striker with sandpaper until a metallic shine is formed, then heat the sledgehammer evenly and slowly until a straw-colored tarnish appears on the sanded surface and leave it to cool in the air. After this, you can start making the handle and think about how to attach the sledgehammer to it.

Handle for sledgehammer

Handles for hammers are usually made of dry thin-layer wood: rowan, birch, ash or maple. Each owner must choose his own handle size, but for a small sledgehammer weighing 2 kilograms, its length is approximately 600-800 millimeters and its cross-sectional diameter is approximately 30-45 millimeters. It is necessary to plan the wooden blank along its entire length with a cross-section that is equal to or slightly larger than the diameter of the sledgehammer hole.

At the top of the handle, the cross-section should be larger than the hole by approximately 5 millimeters on each side. The length of the workpiece is taken 100 millimeters longer, and this excess part must be left untouched during the processing of the entire handle. The handle should fit comfortably in the hand, be smooth, without cracks or knots.

But remember that a sledgehammer, unlike a hammer, must have a long handle. The long handle is needed so that the tool can be held comfortably with both hands. In addition, the sledgehammer handle should be thicker at the top and thinner at the bottom. This is necessary so that the worker does not get dragged behind the sledgehammer in case of an unsuccessful blow. After this, you need to thoroughly saturate the protruding part with used machine oil.

Impregnating the wood with oil will prevent it from drying out, and the sledgehammer will hold very tightly on the handle. In the lower part of the handle, first of all, you need to make a longitudinal cut for the wedge. The best wedges are metal wedges that will go in to a depth that is equal to 2/3 of the width of the sledgehammer head. The sledgehammer should be inserted from below into the widened part of the handle, driving the tool along its entire length against the anvil.

Then the handle should be wedged with a wooden wedge made from harder wood, having first lubricated it with any wood glue. When the adhesive has dried, you need to saw off the excess part of the handle and wedge in such a way that 10-15 millimeters of the handle protrudes above the plane of the sledgehammer. This method allows you to obtain a reliable fastening of the sledgehammer.

During operation (acceleration before impact), the sledgehammer acquires significant kinetic energy and power, and can lead to injuries, disfigurement and even death if handled carelessly. It is necessary to protect the tool from women and children and strictly follow the thermal regime of the sledgehammer. Proper storage of a sledgehammer is carried out in a cool and dry place, away from sources of fire. It is also recommended to lubricate the tool to prevent corrosion.

When choosing this tool, you need to pay great attention to its reliability. Well, if you are thinking about how to make a sledgehammer with your own hands, you need to pay great attention to the length of the handle and the weight of the striker. The hole in the striker should be shaped like a double cone in order to improve fastening, which also makes it easier to fit the striker onto the handle and ensures reliability when wedging the handle.

Use for medical and preventive purposes[edit]

From ancient times to the present day, the sledgehammer has been widely in demand in medicine as the most accessible, simple and effective medical instrument for anesthesia. For these purposes, classic sledgehammers of medium weight (3-5 kg) with a wooden striker and a short handle are used. Anesthesiology teams prefer high-quality branded instruments made of wood (birch, alder, oak, and occasionally beech), while progress in materials science and research has shown a constant increase in demand for sledgehammers made of synthetic materials and special alloys (titanium, magnesium, rubber, plastics) due to significantly longer service life and ease of maintenance, conservation and repair, the latest developments tested in outer space. Practice shows that the use of a sledgehammer is much more effective in pain relief in dental practice and in the treatment of certain types of mental illnesses and disorders. A very important circumstance of shock anesthesia is that the patient suffers much less harm to health due to the complete exclusion of pharmaceuticals and their toxic side effects on the patient’s body. A light, short but strong blow to the patient’s head with a wooden or rubber head of a sledgehammer causes almost instantaneous and prolonged loss of consciousness and very good pain relief. Side effects usually include short-term nausea, headache and, in rare cases, diarrhea. There have been very frequent cases of a noticeable improvement in the patient’s well-being after anesthesia, some sublime joy, smiling and goodwill. In general, the sledgehammer is indicated for use in medicine and is approved not only by the Russian Ministry of Health, but also in the vast majority of developed countries.

In modern medicine, a sledgehammer is also used as a tool for blocking the brain from recording: when copying a person’s consciousness to a backup medium, it is necessary to ensure the integrity of consciousness, therefore, during the operation, all recording to the brain must be suspended. There are no other ways to block a record yet, so a sledgehammer is absolutely indispensable in this area.

The sledgehammer is successfully used to prevent most diseases known to science. After a one-time anesthesia, it is enough to simply keep this device in close proximity to the patient. If there are complaints of malaise, cough, hiccups, etc., it is enough to raise the device to a height of 1-2 meters and gently rock it in the direction of the sick person. The symptoms disappear almost instantly and the patient calms down.
