Sledgehammer for training Mace ST 2290 (10 kg)

Home ▸ Articles ▸ Training ▸ Training with sledgehammers to increase strength

Who would have thought that training with sledgehammers is one of the best ways to increase strength?! But if you have to swing a sledgehammer for any length of time, you will feel pain in your back, shoulders, core, and arms for days, and your forearms will become the size of grapefruits.

However, for training it will be enough for you to devote 5 minutes to the sledgehammer 1-2 times a week. And you will get excellent results. For creating explosive muscle power, nothing compares to this tool.

The benefits of a sledgehammer are that it's fun to swing and hit, it brings out your innate strength and makes you feel like a superhero. In general, no fancy gym with its equipment will give you these sensations.

The impact target is a large tractor tire. The weight of the sledgehammer varies from 2 to 14+ kg.

History of the exercise

It is not known exactly when sledgehammer exercises first appeared. When analyzing the motor pattern, it becomes clear that it has existed for thousands of years. This is the simplest movement that imitates the blows of an ax when chopping wood, working with a hammer in a forge, and even fighting with different types of weapons.

The history of its appearance in the sports field starts with the training of old-school strongmen and circus athletes. They were the ones who actively used the hammer in their practice, but without a tire. However, a significant difference in the development of the “old school” was the weight of the projectile. That is, instead of long sessions, athletes tried to impress with short series of blows, but with incredibly large and heavy sledgehammers.

In modern sports, working with a sledgehammer has become massively popular thanks to CrossFit.

Types of sledgehammers

Tools are manufactured according to GOST 11402 and 1140. Products come in three types:

1. Blunt-nosed
   . A sledgehammer is a tool whose maximum weight is 16 kg. The ends are beveled to an angle of 90º.
2. Pointed transverse
   . Weight 3-8 kg. The firing pin is blunt on one side and horizontally sharp on the other.
3. Longitudinal sharp-nosed
   . The sledgehammer weighs about 8 kg. One end is blunt, and the second is sharpened like an axe.

According to the production method, products are divided into:

• cast;
• forged.

Based on the material used to make the sledgehammer handle, there are:

• made of wood;
• made of fiberglass;
• made of composite plastic.

Blunt Nose Sledgehammer

The most powerful product option. It is used as a percussion instrument, where shocks of different strengths and directions are required. Such a two-handed hammer can weigh about 16 kg. The firing pin is made of steel of different grades (40, 45, 50 or U7). It is mandatory to carry out deep hardening of 30 mm. This type of sledgehammer is used for dismantling work and driving large bolts and piles.

Pointed cross sledgehammer

The weight of such a tool reaches 3-8 kg. As in other models, this one uses different types of steel, which must be hardened. The pointed area is suitable for working on small surfaces where maximum precision is required. A large sledgehammer can easily handle driving stones into the ground or wedging them apart.

Pointed longitudinal sledgehammer

Unlike other options, the striking part of such models is located parallel to the handle. The head of such products, on one side, resembles a chamfered square, and on the other, an ax. Tool weight 3-8 kg. A sharp-nosed sledgehammer is a universal option that can be used to hammer nails or split wood or concrete structures. If you don’t have an ax, you can easily chop wood with this tool.

What muscles work

Even after the first approaches, there is no misunderstanding among the athletes as to why the athletes hit the tire. The movement loads almost all the muscles of the body. The main emphasis is on:

• Back muscles (latissimus, trapezius, lower back).
• Shoulders (all delta bundles).
• Biceps and triceps.
• Forearms.
• Core muscles (responsible for stabilizing the body and transmitting impulses from the legs to the upper limbs).
• Pectoral muscles (with emphasis on the upper, lower and outer areas).

Benefit: what does hitting a tire with a sledgehammer develop?

Training with a hammer and tire is considered perhaps the best way to develop maximum muscle contraction speed. The main advantages of the crossfit hammer:

• Development of explosive power.
• The ability to recruit the maximum number of muscle fibers in working muscles.
• Development of stability (balance), greater load on the core muscles.
• Express grip strength training.
• Development of strength endurance.
• Training coordination and speed.
• Building impressive muscles, with an emphasis on the upper body.

Another benefit of the movement is that it can be used to work the entire body.

How to properly attach the firing pin to the handle

There are at least 2 options for how to attach a sledgehammer to a handle. The striking element can be driven from the end, like a hammer, or passed through the handle and fixed at the top. Both methods have their advantages and disadvantages, but we will focus on the second one, since we consider it more reliable.

We take the striker and place it on the narrow part of the prepared handle.
The task is to drive it to the opposite part of the slowly expanding trunk. Approximately until the middle, the stroke will be free, but the further the firing pin goes, the tighter it will fit to the handle. You can make the hammering process easier in the old, old-fashioned way. To do this, simply hit the thick end on a hard surface, holding the sledgehammer perpendicular. With each blow, the firing pin will drop lower and lower until it reaches the end. The impact element is fixed quite firmly, but can still fly out from prolonged use. To eliminate possible risks, it is necessary to hammer a metal wedge into the handle, where the striker is attached. For this, any plate with a width slightly smaller than the hole in the striker, a thickness of 2-3 mm, and a height of 3-4 cm will do. You can also use wooden wedges, but for this you need to make a cross cut in the handle before placing it on it. striker PVA or epoxy resin is poured into this cut and a wedge of stronger wood is driven in. We hope that the above guide was useful to you and clearly explained how to wedge a sledgehammer and make a percussion instrument with your own hands. We recommend watching the following video, which clearly demonstrates this process. article from the Rating section

How to properly hit a tire with a sledgehammer

In training with a sledgehammer and a tire, the most important role is played by the correct swing and transfer of the projectile for the subsequent swing , that is, the creation of a continuous series of movements.

Least important technical factors:

• Where to hit - you can hit both in the center of the tire and along the edges. The shock absorption of the projectile and the recoil will be the same (but if you want to add rigidity, then hit the very edge).
• Which side to hit - you can hit with the head of a hammer (as with a regular hand hammer), you can hit flat, that is, the striking part of the projectile lies horizontally. This is not essential for this exercise.
• How far to stand from the tire - the distance depends on the length of your arms, handle, technique and other conditions. It is important to stand in such a way as not to create an excessive bend in the lower back (in attempts to reach the projectile), but also not to have the risk of hitting your leg if the sledgehammer comes off the tire.

Key and most important points in technology:

• Foot position – feet should be shoulder-width apart, in a half-extended position (that is, a neutral position between the straight and side stances). One foot is always in front of the other for stability.
• The back is always straight , bending is performed only in the lower back.
• One hand (for example, for a right-handed stance - the left) is always firmly fixed on the lower part of the handle . The second hand “slides” , depending on the position of the projectile. During the lower phase of the swing, it is closer to the head of the sledgehammer. After the projectile falls, the hand “rolls” down the handle to create maximum force.

also important to remember that even if you use a front stance (standing directly to the tire without turning), you need to alternate your swings from different sides. This will force all muscles to work evenly and will not lead to imbalanced development.

How to make a striker

Before moving on to the description of the actions, it should be noted that the process of making a sledgehammer head involves forging, which requires special tools, equipment and experience. If you do not have an anvil and a high-temperature furnace, this guide will only be theoretical for you. You can look for the firing pin on classifieds websites or in markets. In any case, its cost will be less than that of a ready-made sledgehammer. Well, for those who are familiar with blacksmithing first-hand, we recommend that you familiarize yourself with the features of the product.

To manufacture the impact element of the sledgehammer, structural carbon steel grades 50, 45, 55, 50G, 50G2 are used. This metal is used in the production of truck axle shafts, so if you don’t have the suitable material, you can look for it at your nearest auto repair shop. To work, you will need a rectangular piece weighing 3 kg, from which you need to forge a parallelepiped.

The next step is to place the handle.
To do this, on one side, in the center, we punch a through hole with a diameter of 25 to 30 mm. The sides of the workpiece are deformed. Having freed the hole, it is necessary to forge the side edges so that the object again takes the shape of an even parallelepiped, and the round hole becomes oval. In order for the attachment point to be most reliable, it must be given a cone shape, tapering from the side edges to the center (in the cross-section of the striker it resembles an hourglass). For this operation, you will need to forge a special calibration rod from cone-shaped steel. The cross-section of the caliber should be oval, and the length should be 180-200 mm. The lower part of the section should be a couple of millimeters narrower than the hole made in the striker, and the upper part is slightly larger than the handle that you are going to install. After forging, the gauge must be hardened and ground.

To properly calibrate the hole, drive the steel rod to a depth just below the center of the striker. When the caliber is deepened, the side faces will be deformed. They need to be straightened by removing the gauge and forging the ends of the workpiece. Next, drive the gauge into the hole again, and without removing it, forge the sides and bead the ends. When the workpiece has the shape of a regular parallelepiped, we repeat the calibration process on the other side of the hole.

When the striker has the correct shape and a reliable attachment point, you can proceed to the hardening stage. In order for the steel to become truly hard, it must be heated to 850 degrees Celsius until the workpiece takes on a bright red color. Once the required temperature is reached, immerse in cold water until cool.

Now that the steel is hardened, it is necessary to give it ductility so that it does not crack during operation. To do this, heat the product to 250-300 degrees and let it cool slowly. After cooling, we grind the metal surface and read how to attach a sledgehammer to a wooden handle.

Recommendations

Given the benefits of using a sledgehammer, the approach to training depends entirely on the athlete's goals. To develop explosive power, it is recommended to choose a heavy implement with a long handle, performing short sessions (9-15 repetitions). For moderate weights, a regime of 21 repetitions per round is suitable.

For endurance training and metcons, the range of repetitions can be from 10 to 50, depending on the combination with other exercises. If you do pure work with a sledgehammer without other movements, then the 10*10 option is also often used (that is, 100 repetitions in 10 series).

CrossFit complexes with a sledgehammer

The sledgehammer is rarely seen in professional and competitive settings. However, it is great for explosiveness training, metcons, and off-season training.

Examples of effective complexes.

Tabata

Performing 8 series of 20 seconds of work and 10 seconds of rest at maximum intensity.

Bundle for beginners

Series from:

• Right hand strokes – 4*15.
• Backhand strokes – 4*15.
• Overhand strikes with two hands – 4*15.

You can do all the movements one by one, or each one separately.

Power complex

• Hammer blows – 21.
• Swings with a kettlebell to the chest – 15.
• Pulling a tire - 20 meters (pulling it with the head of a sledgehammer).

The best chisels for rotary hammers

This category of equipment in the rating is used together with hammer drills. The chisel is inserted into the chuck of the power tool and makes blows from the “drunk bearing” in the gearbox. Using such equipment, you will be able to quickly make large holes in the masonry, dismantle partitions or remove the old layer of finishing.

Rating: 4.9

This is a rated German product produced at production facilities in China. The tooling is made from an 18mm hexagon with a spade-shaped spattered end. The cutting edge width is 25 mm and is optimal for both removing the outer layer and plunging into the material. The length of the chisel is 600 mm and it is designed for use in impact mode without rotation. The shank is made in the SDS-max configuration and is only compatible with large construction hammers.

According to our experts, the chisel should be in the ranking of the best due to its large length of 600 mm. This is one of the maximum indicators, which is suitable for punching ventilation channels and laying pipes in the walls of houses with a cross-section of 500 mm (Stalin buildings), in order to do all the work on one side and avoid overlapping holes. According to reviews, this is a durable chisel that will last a long time and does not need regular sharpening.

Advantages

• one of the largest chisels in the category;
• wide blade 25 mm;

How to choose a sledgehammer for CrossFit

This is a very non-standard exercise, because it is important not only to understand how to correctly hit a tire with a sledgehammer (which is important for all movements), but also to choose the right implement. With the wrong hammer, it will be impossible to maintain the correct technique, which ultimately can lead not only to a deterioration in efficiency, but also to an increased risk of injury.

The first thing to start with is understanding that you need a sports sledgehammer. Technical hammers (for example, railway hammers) are most often not suitable because they have offset balancing.

• When choosing a weight, it is recommended to start with 4 kg shells. This is optimal for athletes with low and average levels of physical fitness. To use a 16-kg sledgehammer and hit a tire technically correctly, you need very serious training and experience.

• The length of the handle should depend on the weight of the hammer, the height of the athlete and the training style. The absolute minimum is 30-35 cm; such models are not used for crossfit, but are sometimes used to work in series with one hand (Donkey Kongs).

Standard dimensions for a regular CrossFit hammer made of steel in centimeters:

It is also highly recommended to use models with non-slip handles made of rubber or other material. They increase the chances that the projectile will not fly out of your hands when hitting the wheel.

Types of crossfit hammers

• Rubber projectiles are mainly used by girls, as they allow you to combine standard sizes and light weight (which is unattainable for metal alloys).
• With adjustable weight - the head has a special hole for pouring metal balls. Allows you to adjust the weight, but has a drawback - the ball makes a lot of noise during operation.
• One-handed hammer - for performing exercises with one hand. Has a shorter handle length and weight.
• The standard sledgehammer is the most popular and widespread projectile.

The best sledgehammers weighing from 7 kg

This tool is used for blacksmithing or driving massive reinforcement. It is convenient to work on and feels like a small anvil on which you can tap something with a hammer. To use such a sledgehammer you need good physical training.

Sledgehammer 7000g Pavlovo 10965 – for forge

This is the best sledgehammer for working in a forge due to its weight of 7 kg and the presence of selective hardening of the striker. Its surface is covered with anti-corrosion paint, and the handle is completely wooden, which protects it from melting when in contact with hot objects.

The main part is made of steel St40-60. The handle is well dried and has a moisture content of no more than 12%. The hardness of the striking part is 48-52 HRC.

Pros:

• you can monitor the quality of the fit thanks to the open part in the striker;
• handle length 700 mm is optimal for strong impacts;
• polished handle with ergonomic cutouts, tapering at the end;
• The anti-corrosion coating BT-577 will preserve the metal for a long time.

Minuses:

• cost from 1350 rubles;
• no rubber pads;
• there are no stops to prevent slipping;
• very simple design.
