Do-it-yourself bench press and abdominal exercise machine: drawings, how to make

Modern life, on the one hand, deprives a person of most natural physical activities; on the other hand, it throws bundles of psychological and emotional loads at him. Therefore, absolutely everyone needs to keep themselves in good, at least physical shape. To the credit of the current generation, we can say that now most people understand: a healthy mind in a healthy body. They also soon begin to understand: physical exercises, dumbbells and wrist expanders are not enough; you need to work more with weights on apparatus and machines, so at least a bench is required.

Not just spirit

A healthy body is also necessary for a developed mind. Physically undeveloped outstanding scientists, engineers, creative intelligentsia, top managers and businessmen are the exception rather than the rule. Leo Tolstoy at 60 was spinning the sun on a horizontal bar. Niels Bohr, the one in school textbooks, was a famous football player who played for the Danish national team. Things got funny with him: when Bohr was awarded the Nobel Prize in physics, of course, the Copenhagen Tagebladette published a note saying, it’s good, our forward was given a Nobel Prize for football. And a “nerd” in “physics” often turns out to be one in areas of activity that require mental effort.

The abdominal muscles are known to be more difficult to pump than others, because... their ends are not directly connected to the bones. At home, doing abdominal pumping without special equipment, it won’t take long before you get a hernia. Therefore, you need a bench for the press. Structurally, both apparatuses are most often combined into one, with the possibility of conversion for certain sets of exercises.

Sports benches are not technologically complex products. There are enough descriptions of them in RuNet, but more in the spirit of: choose the drawings, and then - this is how you have to saw, pound like this, screw like this. A person who cares about his physical development, as a rule, knows how to operate a tool. But how to choose a prototype so that your training benefits? How to modify it to suit your biomechanics and biometrics? Which sample is more suitable for certain groups of exercises?

This publication is devoted to the questions of how to make a bench for exercises in the preferred direction of physical development with your own hands, using a reasonably chosen model, and then, based on it, a home exercise machine. Those who intend to prove themselves in sports or bodybuilding by working out in it will not be ashamed to come to a well-equipped professional gym. In the meantime, the material is designed for beginner athletes and simply for people who understand: you can and should use the benefits of civilization, but letting them turn you into a twitchy “teapot” or a swollen kettle is wrong.

Note: the problem of home sports activities has recently become more and more acute in rural areas - “physics” is decreasing there, stress is increasing, and a well-equipped gym is sometimes far away.

Why do you need to make a stand yourself?

Why do you need to make a stand yourself, if you can find a decent stand that will be of high quality and practical in online stores or sports stores? First of all, a do-it-yourself barbell stand will cost three or even four times less than a store-bought one. All you need is to have all the tools and be able to use them.

Secondly, your own stand will suit all personal parameters. There will be nothing superfluous in it, and the design can suit any conditions of your own apartment.

What to choose from

A home bench press bench is most often included in a compact exercise machine or is itself a multifunctional sports equipment. Regular exercisers will probably end up with a simulator, so when choosing a prototype bench, you need to keep in mind what it will acquire later. The most common designs of sports simulators are 4-, 3-, and 2-support. “Support” in this case does not mean the number of points of contact with the floor (usually there are at least 4 of them, for stability), but the number of vertical force connections in the structure; it largely determines the capabilities of the projectile.

Types of home exercise equipment

4-support projectiles, pos. 1 in Fig., are intended for developed athletes who operate with large, over 100 kg, weights. The racks for the barbell are located in them at the level of the shoulders of the person lying down, which greatly reduces the risk of injury: a barbell collapsing with the bar on the chest is very serious. 4-support exercise machines are heavy, cumbersome, and you can’t exercise with heavy weights in an apartment: falling on the floor, they give an instantaneous load of 5-8 of their weights, and the load-bearing capacity of the floors is 250 kg/sq. m.

For domestic conditions, 3-support exercise machines are intended, simple and with additional levers for weights, leg supports, athletic desks, etc., pos. 2 and 3. To ensure that the bar of the barbell in a 3-support machine also falls at shoulder level, their benches are made to “break”: it is dangerous to pick up the barbell with your hands behind your head. Therefore, in terms of dimensions, 3-support simulators are generally no smaller than 4-support ones, excluding those in which the barbell is taken from the approach, see below. The permissible working weight in 3-support equipment is usually 100-120 kg, including the trainee’s body weight.

A 2-support exercise machine is actually a bench for the press. For different groups of exercises, horizontal and inclined benches are needed, pos. 4 and 5: on a horizontal bench the abs swing, and on an inclined bench the lumbar muscles are also well loaded. A more complex structurally universal bench, pos. 6, serves in both capacities.

Note: You can also do initial sets of hyperextension exercises on an incline bench, see below.

The most advanced type of sports benches is a transforming bench with a breakable board, the inclination of the parts of which is individually adjustable, pos. 7. The transforming bench can be supplemented with a stand for a block with a load, a desk, pos. 8 and other devices. It makes sense to do one for yourself right away if you have the necessary working skills: then adding a barbell rack to the bench, we get a complete analogue of a 4-support exercise machine, only with less weight, pos. 9.

Erroneous design of a transformable sports bench
Note: a common mistake when making transformable sports benches yourself is to make them according to a power circuit, as in Fig. on right. When performing exercises, significant forces arise, tending to “spread the bench of the legs,” and the welds turn out to be unreliable. In order for a projectile of this type to become durable, its supporting beams must be connected with a longitudinal beam, or two, from the same pipe.

Layout

So, the decision has been made - the barbell rack will be homemade. Before starting work, you need to think through everything carefully. For greater accuracy, it is best to make a drawing. The barbell stand must be proportional. Load-bearing structures must support the entire weight; for this, everything must be calculated and plotted on the drawing. In addition, the drawing will help you avoid buying too much. Since materials are usually bought by eye with a reserve, and this is all money. What is important for a homemade stand is low price. So it is better to first draw up a plan in which the future stand should be described.

Special benches

A special type of sports equipment is benches for hyperextensive exercises. Their goal is to achieve leanness and flexibility without gaining excessive muscle mass. In fact, hyperextension can be done on a large ball, or just on a mat, but the best results are obtained on a special bench.

Hyperextension benches

Benches for hyperextension, due to anatomical and physiological differences, are available for men and women, see fig. A strong Amazon can do hyperextension exercises on a men’s bench, but ladies whose goal is to get rid of riding breeches, have a slender posture and a flat stomach only need a women’s bench for hyperextension, on the left side of the trail. rice. To start getting yourself in order without risking your reproductive health, it’s still better to sit on an inclined bench with a curved board, or do press exercises with a weight, also sitting on a special bench, on the right.

Special benches for sports exercises

Note: drawings of a hyperextension bench with height adjustment are given in Fig. Materials – profile pipe 40x25x2, 35x15x1.5 and round 25x1.5; desk made of plywood 12-14 mm. For desk lining, see below.

Bench drawings for hyperextension exercises

hanging bench

One of the best exercise machines for the abs and abdomen, which is quite easy to do with your own hands, is a hanging bench for an existing vertical ladder.

To make it you will need:

a board with a length of 100 cm depending on the height of the athlete and a width of at least 40 cm for maximum comfort;
fastening element - bolts, nuts;
timber for fastening to the wall bars.

The board is made with a base of metal pipes that cling to the step. Hand holders are installed above the stairs. A detailed set of materials and drawing can be seen in the figure.

Materials and assembly diagram of the hanging bench

About sizes

Here in Fig. The dimensions of 3-support exercise machines for people of average height are given. On the left is a fully functional one with a removable desk, hand and foot levers. The main materials are corrugated pipe 60x40x2 and round pipe 30x2; stop for lifting the board – pipe 20x2. The board is 16 mm plywood with sheathing, as described below.

Dimensions of home exercise equipment for people of average height

On the right is a simple compact one. The height of the bench above the floor is selected individually, measuring from the heel firmly planted on the floor to the inner bend of the knee joint. Basic materials as in the previous case; The adjustable rear leg allows you to transform the apparatus for seated exercises. But remember: the barbell from this simulator should only be lifted from the approach!

Alternative options

Variations of the front squat with the barbell secured on the chest using crossed arms and straps can be used at the initial stage or for those involved in bodybuilding or powerlifting. If the goal is to master the technically correct body position for weightlifting, the athlete must seriously address forearm stretching and shoulder and hand mobility.

Forearm stretching exercises are included in each complex with a front squat, and are performed at the beginning of the workout for 10-15 minutes. Usually this stage is not very popular for beginners without good stretching and mobility, but it is necessary in the process of physical development of the future athlete.

Various benches

The simplest, but also remarkably durable sports bench, the “Hippolytovka”, can be made according to the drawing in Fig. flooring – durable board from 40 mm. Those who took the young fighter course in the army are well acquainted with it; at least in past times. The “spirits” of the townspeople soon began to look at the Ippolitovka with amazement and apprehension: how many different exercises, it turns out, can be done on it! And it fits perfectly into the 4-support simulator.

Sports shop frame

On the trail. rice. – inclined bench for the press. Due to its compactness and usefulness, it won’t hurt to have a separate one if there is enough space in your home. Due to the absence of right angles, the material is weaker - 40x40 corrugated pipe. Foot rests – 10 mm rod with threaded ends, rubberized to the required size. The rubber couplings are removable: the lower stop is adjustable, and the top one can be removed if you need to do exercises in which it interferes.

Drawings of an incline bench for the press

Next in Fig. – compact power bench with racks for barbells. Exercises on it are done mainly while sitting. You can also pump up your abs by deeply arching your back. In this case, the foot rests will be the transverse beam A, and then it needs to be covered with something soft or put on a rubber coupling. The materials are 40x40 corrugated pipe, and the rod holders are made of steel strip with a thickness of 6 mm.

Compact weight bench

The next example is an athletic bench for strong guys who can confidently handle a barbell of weight equal to their own, the so-called. Scott's desk. The materials, respectively, are corrugated pipe 60x60x2.5 and 50x50x2. The neck holders are made of the same strip as in the previous one. case; seat and table made of plywood from 20 mm.

Several simulators

How to tightly connect a hippolyte bench with a barbell rack, turning it into a fairly compact 4-support exercise machine, is shown on the left in Fig. There on the right are the dimensions and design of the transforming bench for the same frame. The main material here and there is 40x60 corrugated pipe. Let's talk about the rack clamps with rod holders below.

Home exercise machine and transforming bench for it

On the trail. rice. – drawings with a bill of material for a simple 3-support stationary non-adjustable exercise machine with a horizontal bench. It is more suitable for private households with a sufficient usable area. The highlight of this design is the connection of the far leg of the bench with its supporting beam with a link at 45 degrees. Thanks to the optimal distribution of operational loads, it was possible to make a projectile on which you can do exercises with weights of more than 100 kg, from a 50x50 corrugated pipe.

Simple three-legged home exercise machine

Finally, further in Fig. – drawings and specifications of elements for a full-functional home exercise machine with a transforming bench for bench press and abs. Notice the node highlighted in red. This is the simplest and most reliable way to fix barbell racks for use at home. The locking pins (with a diameter of 12 mm or more) will, of course, wear out little by little, but they will never jam or bite.

More about the barbell

As already mentioned, a barbell that is not supported by weight can cause severe injuries, even death. And in such cases it is unrealistic to direct its neck into the holders. But it’s realistic to provide 2 pieces of chain, securely fastened to the rod racks. At the other ends of the chains there are carbines, they are thrown onto the bar. The length of the chain safety links is taken such that, holding the barbell with fully extended arms, the chains sag, but the bar of the released bar does not reach the chest. To prevent the carabiners from slipping on the bar, it is enough to tape them with tape. Suddenly the barbell collapses, the tape, of course, won’t hold up, both carabiners will move to one end of the bar, but the result will be fear and, possibly, a broken floor.

About wooden athletic benches

You cannot train with barbells on wooden sports equipment; their design will not hold up. But in situations that arise as a result of the awkwardness of the trainee, wood “radiates” through the body much less sensitively than metal. Therefore, it is preferable for beginners and minors to use wooden benches for bench press and abs. In addition, wooden sports benches and exercise equipment can be built at the dacha or in a country house from leftover building materials.

Drawings of an inclined wooden bench for the press

The design of an inclined wooden bench for the press and the specifications for it are shown in Fig., and on the next. rice. – drawings of a wooden exercise machine with an inclined bench and a lever for leg exercises with a load. In order for the tree to support operational loads, a block system for hanging loads is used: they hang on the descending branches of cable A. Cross beams B are rubber-coated steel.

DIY ab roller

Homemade ab roller
The simplest version of a sports equipment for working out the abdominal muscles. You can do it in two ways, the first will require:

2 wheels of the same size;
steel tube with thread 40 cm long.

The diameter of the pipe must exactly match the hole in the center of the wheel. The wheel for such a simulator must have a diameter of at least 10 cm, but no more than 20 cm, so that it is convenient to exercise.

Assembling the structure is quite simple: the pipe is cut, its edges are rubbed so that there is no sharpness, and a wheel is put on the center.

Threaded tube is an interesting material that is not always easy to find. However, anyone can contact the factory where the fasteners are made, or a private company to apply threads to a simple round bar. All that remains is to find a company that works with retail clients.

To keep the wheel in place, it is put on in the center and secured on both sides with suitable nuts. Gymnastic pads are put on the ends of the apparatus, like on hand dumbbells or exercise bars.

About covering boards and seats

The boards and seats of industrial sports equipment are covered with leatherette or plastic for a similar purpose on an elastic lining. Such covering is durable, but does not prevent the reabsorption of sweat, which is in no way beneficial; This is why modern sports uniforms are made in 2 layers, with a mesh that immediately removes sweat directly from the skin.

In gyms, this lack of cladding does not have a noticeable effect, because... the gym is equipped with supply and exhaust ventilation (PVV) and air conditioning. At the very least, it must be equipped in accordance with sanitary standards. It is not always possible to exercise at a comfortable temperature at home, and it is simply technically impossible to arrange PVV in many city apartments. Therefore, it is advisable to cover homemade athletic benches in the form of such a “pie”, following from the base outward:

Microporous rubber with a thickness of 12 mm;
Furniture foam rubber with density 45 (grade 45) with a thickness of 8 mm;
Sintepon with a thickness of 7 mm;
Denim or material like the old-style flannelette soldier's blanket.

The rubber damper is glued to the base with Moment glue or hot glue from a glue gun. The remaining layers of sheathing are folded to the underside and pinned with a furniture stapler. The disadvantage of such cladding is that it needs to be changed once a year, at the end of spring; the rubber layer remains. The soft layers will not harden, perhaps within 3-4 years, but according to sanitary and hygienic requirements, the service life of the textile lining should be reduced to a year.

Buy or make it yourself

Playing sports has a positive effect on human health, but it is not always possible to go to the gym and pump up muscles. So, to solve this problem, thanks to the fairly compact size of the bench press machine, you can install it at home.

The question immediately arises of whether to buy or make a simulator with your own hands.

To answer this question, consider the advantages and disadvantages of one and the other option for purchasing a bench.

Option for purchasing a bench	Advantages	Flaws
Buying a bench press	A wide range of simulators and their configurations.	·High cost of goods. ·Inadequate quality.
Making a bench with your own hands	·You can make a bench at your own discretion, taking into account all the features and wishes of its owner, and, most importantly, with high quality. ·To make a bench, you can use less expensive, but still high-quality materials. · Even taking into account the funds spent on purchasing materials for making the bench, the cost of the product will be significantly less than the store price.	Waste of time

Based on the above, it becomes clear that the option of making a bench press with your own hands is still the leader, but taking into account the fact that not everyone has the opportunity and skills, it will still be easier to buy a machine. It all depends on the financial capabilities and preferences of the owner.
