Low bow, my dears! Summer is in full swing, but we still can’t calm down and stuff you with notes. Probably already tired of it? :) And yet, today we are waiting for another technical note about the abdominal roller exercise. After reading the article, you will become familiar with its advantages, as well as the technique of implementation. In addition, we will reveal its effectiveness for creating a steel press.
So, make yourself comfortable, I'm giving the third call.
Ab roller exercise. What, why and why?
Believe it or not, it is also possible to shape your figure at home. Of course, there is no need to talk about the pain of muscles, but creating a certain general elasticity and giving muscle tone is a completely feasible task. Various types of home sports equipment can help with this. We’ll talk about one such fitness device, the ab roller, next.
The first time I met this rolling machine was in a physics lesson when I was still a schoolboy. As usual, the curious Protasov, a student of the 7th grade, went where he shouldn’t have gone, namely, into the physical education teacher’s back room. After rummaging through various rubbish, I found a wheel with handles, which seemed very unusual to me. I had no idea how to use it, so I just rolled it around and then ran after it across the floor. It soon became clear that the principle of operation of the rolling wheel is somewhat different, and it is called an ab roller, designed to strengthen muscles abdominals. Our next meeting with the video took place in a different, more familiar environment, namely in the fitness room of a local club. Both of them were interesting, memorable, and therefore it was decided to dedicate a note to this fitness equipment.
Actually, let's move on to the theoretical and substantive part, let's go.
Note:
For better assimilation of the material, all further narration will be divided into subchapters.
Muscle atlas
The ab roller is an inexpensive fitness equipment that is designed to strengthen the core and abdominal muscles. Despite the simplicity of the exercise technique, rolling a roller causes a lot of difficulties due to the weakness of the entire abdominal region of the abdominal muscles, as well as the back areas. The rectus abdominis and obliques actually contract isometrically with slight flexion at the waist under resistance. In the absence of waist flexion, the rectus abdominis and external obliques act as pelvic and waist stabilizers during hip flexion.
The complete muscle ensemble is the following set of muscles:
- target region – iliopsoas muscle;
- synergists – tensor fascia lata, sartorius, pectineus, adductor longus/brevis, latissimus dorsi, teres major, major (sternal region)/ pectoralis minor, posterior deltoid, rhomboid;
- stabilizers – rectus abdominis, obliques, triceps, pectoralis major (clavicular region), wrist flexors;
- dynamic stabilizers – rectus femoris muscle;
- antagonist-stabilizers – erector spinae muscles.
IN picture version muscle atlas looks like that:
Advantages
By doing the ab roller exercise, you will get the following benefits:
- development of abdominal muscle strength;
- creating a strong muscle corset - strengthening the core muscles;
- immediate involvement in work large quantity(before 20 ) muscles;
- greater activity of the rectus and oblique abdominal muscles compared to crunches;
- increased endurance;
- improved posture;
- reduction of back pain, prevention of injuries;
- increasing working weights in squats;
- improved muscle coordination;
- increase muscle mass, increasing basal metabolic rate (improved ability to burn calories during periods of inactivity).
Execution technique
The abdominal roller exercise is not without its subtleties and nuances, and therefore it is important to know how to perform it correctly. To figure this out, let's go step by step through the technique of doing it.
Step #0.
Take the roller in your hands and take a position on the floor, standing on all fours. Place the roller on your outstretched arms, strictly under your shoulders, lock in this position. This is your starting position.
Step #1.
Inhaling, slowly begin to roll the roller forward in a straight line, pulling your body along with it and stretching it. Continue moving forward as far as you can without your body touching the floor. After a pause in the stretched position, pull yourself back to the starting position, exhaling to contract (closer). Repeat the specified number of times.
In the picture version, the exercise with a roller looks like this:
In motion like this...
Subtleties and secrets
To get the most out of the exercise, follow these tips:
- roll the roller back and forth slowly and under control;
- keep your abdominal muscles tense throughout the entire movement path;
- stay for 1-2 accounts in an extended position;
- perform the exercise with your knees on the mat;
- to develop strength abdominal muscles and create a strong encircling corset, include the exercise along with the bar in your abdominal training;
- As you progress, also use diagonal roller rolls;
- do not perform the exercise if you have pain in the lower back and hernias;
- recommended number of approaches - 2-3 , reps 8-12 .
Variations
In addition to the classic roller rental option (which, by the way, is a rather advanced and difficult version of the exercise) note the variations:
- on fitball;
- reverse roller ("penknife");
- rental of barbells with pancakes.
Actually, we’re done with the theoretical part, now let’s look at the practical calculations.
The best exercises for the upper/lower abs, what are they?
During an experiment at the University of Massachusetts Exercise Science and Physiology, electrical activity was measured in the muscles of the upper and lower abs while performing various exercises. It was found that renting a video in comparison with 5 the most popular abdominal exercises, showed the highest EMG values for two areas - 80% for the top and 85% for bottom, against 70% And 80% , from the nearest pursuer, raise your knees while hanging on the horizontal bar.
Conclusion – one of the best complex exercises on the press is a rolling roller.
Ab roller VS crunches. What's better?
When performing crunches while lying on your back (), the torso is lifted off the floor, the rectus abdominis muscle contracts and the distance between the ribs and hips decreases. When rolling a roller, the rectus abdominis muscle performs an isometric, static contraction throughout the entire range of motion. When the wheel approaches, p.m.f. contracts, reducing the distance between the ribs and hips.
Most effective exercises on the press are those in which during movement the use of third-party muscles (hip flexors) minimal. Thus, involving the hip flexors in abdominal exercises reduces their effectiveness. When performing back crunches, the hip flexors remain in place. (because the knees are bent and do not move). When performing the ab roller exercise, the angle at the hips increases and decreases, so the abs receive help from the flexors.
Conclusion. Crunch - more isolated exercise on the press, roller - more complex. They cannot be compared with each other, because... they solve slightly different problems, the first is targeted development of the midsection, the second is the development of strength and the creation of a muscular corset that encircles the waist. The most effective strategy for training your abs is to use crunches. (and it’s better on a fitball) and a video on one program day.
Ab roller VS plank. Who will win?
No one no one :) ... these exercises have the same “principle of action”, in which the abdominal muscles contract isometrically, which, in turn, means that the muscles work to keep the spine in static position. When a person stands/sits, his abdominal muscles work isometrically to maintain an even posture. Developing isometric strength is important for a person and helps keep the spine in the correct position for a longer time. In addition, isometrics are important when performing work with a barbell, such as squats.
Conclusion - to build not only the shape of the abs (a.k.a. cubes), but also to develop the strength of the abdominal muscles, use exercises of different “principles of action.”
This was the last information that I would like to convey, now let's summarize.
Afterword
Today we got acquainted with the abdominal roller exercise, which means that you are one step closer to building the body of your dreams.
So, let’s finish reading the theory and head to the gym for practice, good luck!
PS. And you are skating, how are you doing?

The main purpose of the roller press is the cladding of MDF, chipboard, fiberboard and other board materials. Such equipment is also suitable for processing pre-profiled sheets with plastics and films.
Most often, roller presses are used in medium and large-scale production. The unique installation is indispensable in the manufacture of countertops, kitchen furniture and office interior items. Roller presses are usually used in conjunction with softforming and postforming machines.
Features of roller presses
In roller presses, workpieces are fed using upper and lower rubberized rollers. Modern equipment allows you to adjust the feed speed using the control panel (on the front plane of the bed). Thanks to the ability to regulate the operation of the system, it is possible to eliminate the possibility of damage and slipping of workpieces.
To adjust the thickness of the roller press, a screw pair is provided (the handle is located at the end of the machine). You can control the accuracy of the measurement using the indicator scale. Please note that the upper pressing roller must be in the upper position when adjusting.
During pressing, the force is provided by pneumatic cylinders, which makes it possible to perform the cladding more efficiently. Upper heating elements are used to heat the facing material. This system allows for secondary activation of the binder, resulting in a stronger connection. The heating temperature of the heating element can be changed at any time using the control panel. When creating roller presses, special attention is paid to ensuring safe operation of such equipment. A reliable protective screen is installed at the front of the machine. In addition, emergency shutdown buttons are provided at the output.

An ab roller is called sports equipment having quite simple design. It consists of a handle divided into left and right sides by a wheel, which is located in the middle, making it as comfortable and convenient to hold with both hands. The simplicity of the device does not mean that it has low efficiency.
Exercises performed with a roller pump up the abdominal, back and triceps muscles well. This is only true when the execution technique is followed. Training with a roller is highly effective, and for most exercises you need to be a fairly experienced athlete.
Sports equipment must be such that it supports the body well and allows it to move backwards and forwards without jerking. A gymnastic rigid roller has a device that allows you to exercise on a tile or mat without making intermittent movements. The device, which has a double wheel, has a wide base and distributes the mass as evenly as possible.
It is recommended to choose a wheel so that it maintains its stability under the weight of the athlete while rolling. For beginners, I find it easiest to work with rollers that have two parallel wheels or one, but quite wide one. To achieve good stability, you must choose a rubberized wheel. It is stable on absolutely any surface. The device should have ergonomic handles made of foam.
This material allows you to firmly hold the wheel and maintain balance well. There are designs equipped not only with handles, but also with pedals. Similar types of rollers help to diversify the set of exercises performed using this sports equipment. The handles must fit snugly on your palms, and the pedals help support your feet without any slipping.
Ab roller exercises require good preparation. Without well-developed muscle mass, it is impossible to provide adequate support for body weight when doing rolling. The use of the roller forces the body to move, and the spine is stretched during the entire movement. This poses a challenge for the deep-lying spinal stabilizers and the rectus and transverse abdominal muscles.
This impact makes the roller an ideal device for pumping sculpted and strong abdominal muscles. The movement also uses the auxiliary muscles of the hips, shoulders, latissimus, and triceps. They are responsible for stabilizing the body from the shoulder girdle all the way down to the toes, which allows you to maintain balance when the wheel rolls under the body.
9 Ab Roller Exercises
You should work with the device from a simple plank, but with support on a roller wheel, and only then move on to more complex ones, that is, when you have complete confidence that you can move on to exercises that involve the knees, and only then to a full roll and other more complex variations. An absolute beginner can work with a fitball first.
The plank performed with the help of a wheel strengthens the stabilizing muscles and also helps to get a feel for how to properly hold the roller and balance.
Technique:
- get on all fours in front of the gymnastic roller;
- grasp the handle with both hands, palms pointing down;
- the torso is raised to a plank position, and then straightened in one line from the head to the very heels;
- the body is kept in constant tension and held in the accepted position for 30-60 seconds.
Do three to four repetitions.
This is the next most difficult exercise, which allows you to move to a new level of difficulty. At first, rolling from your knees is best done with a folded towel or flat pad underneath.
Performance:
- kneel down, grab the handles and stretch out your arms;
- to avoid arching the lower back, tense the abdominal muscles;
- roll forward slowly as much as possible;
It is best to extend your arms as far forward as possible so that your chest is slightly higher than the floor surface. If this is difficult to do, then lower them halfway. The number of repetitions ranges from five to ten times.
It is best to start doing the exercise with small ranges, increasing progress gradually. Each athlete chooses the optimal rental length for himself. You need to move until you are able to return back by using your abdominal muscles.
This is another option for beginners, allowing you to perfectly maintain both the fixed length of the video and the pace of the training. Using the wall as a focal point. It is recommended to roll rather slowly.
Execution:
- stand about a meter from the surface of the wall;
- roll from the knees so that the roller comes into contact with the wall;
- return to their original position.
Do from five to ten repetitions.
Performing a full roll with a roller is an exercise of increased difficulty, but with a wide stance it is much easier to do. When the exercise is mastered, the position is changed, narrowing the distance between the legs, until a full roll is completed.
Performance:
- legs are placed shoulder width apart, bending at the waist, and then grasping the handle of the roller lying on the floor;
- keep your back and arms straight and roll forward until your torso becomes horizontal to the floor surface, rest your feet on your fingers, similar to push-ups;
- the wheel is rolled back towards the legs and again bent at the waist to return to the starting position.
Do from five to six repetitions.
When rolling from your knees wide stance mastered, they move on to full rental, but with a narrow stand. The exercise allows you to effectively use the muscles of the whole body and involves the muscles of the shoulders, back, abs, and arms.
The next option after the frontal exercise is the oblique roll. The main emphasis in the exercise is on the oblique muscle groups of the abdomen.
Execution:
- get down on both knees and grab the handles;
- but, instead direct movement, begin to roll forward, and then turn at an acute angle (45 degrees), completing the exercise in this direction;
- return to the starting position, and then slowly roll at the selected angle to the right.
Do about five or ten repetitions.
This rental is a complex version of the frontal. The weight is held by the hand on the roller. The main advantage of this exercise is the creation of additional tension on the stabilizer muscles. Initially it is quite difficult, so you should not start with full version. It is better to practice rolling from your knees first.
Performance:
- kneel down or stand directly in front of the roller, depending on whether they are practicing or working;
- bend at the waist, and then grab the handle with one hand;
- slowly move forward, focusing on the muscle groups of the body;
- return to their original position.
Do from three to five repetitions. When rolling, make sure that the body does not tip to the side. To maintain balance, you can stick to the floor surface with your free hand.
On one leg
This is a more complicated option that requires great strength from stabilizer muscles. You should proceed to this exercise after mastering a full roll on two legs.
Execution:
- stand directly in front of the projectile;
- bend at the waist and grasp the handles of the wheel;
- keep your back straight, and extend your arms and roll them forward;
- return to the starting position, standing on one leg and bending at the waist again.
Do about five to ten repetitions.
This variation of rolling requires the use of a roller, which is equipped with special pedals for the feet, since rolling is carried out not with the hands, but with the lower limbs. This exercise uses the arms, shoulder girdle, oblique and abdominal muscles.
Performance:
- the feet are secured in special pedal devices and stand in a plank position, keeping them straight elbow joints hands under shoulders;
- roll the wheel using your legs so that both knees move towards chest, holding top part still;
- straightening knee joints until they return to the plank position.
This variation engages the stabilizing muscles and obliques.
Execution:
- the feet are fixed in the pedals and stand in a plank position, arms extended in front of the shoulder joints;
- the wheel is rolled with the feet and moved to the right elbow;
- return to plank position and roll to the left.
Perform eight to twelve repetitions.
This variation resembles a fold, but the legs are kept straight:
- the feet are also secured in the pedals and stand in a plank position, arms extended under the shoulder joints;
- engage the muscle groups of the body and slowly roll the roller wheel to the top, bend at the hips, lifting gluteal muscles up;
- roll the roller to its original position.
Do from eight to twelve repetitions.
The abdominal roller may seem quite simple to use, but it requires serious effort from the athlete, and, most importantly, well-developed muscle groups of the body, since they are activated during the roll.
If exercises are done incorrectly, the excessive stress placed on the back muscles and hip flexors increases the likelihood of injury. They are not recommended for those people who have problems with intervertebral hernia or lower back.
To comply correct technique to avoid injury when working with the roller, you should follow several rules:
- always check that the movement is carried out with the help of a wheel, and not due to the movement of a mat located on the floor;
- do not bend in the lower back and do not allow the body or knees to touch the floor surface;
- always keep your back, legs and arms straight;
- do the rental, regardless of the degree of difficulty, slowly, increasing progress gradually;
- reduce the range of motion if there is pain in the shoulder girdle;
- concentrate all your attention on the abdominal muscles.
A proper ab roller workout involves maintaining a slow speed. When the back begins to sag, it means that the ride is either done from the knees or the length is shortened. Keep your head in a neutral position and keep your chin slightly tucked in to help protect your neck and lower back.
It is recommended to perform exercises with a roller after a good warm-up, since they immediately put an intense load on the muscles of the whole body. At the end of the training, do a cool-down, that is, a good stretch. Beginners should use the wheel twice a week, and only then increase the number of training days with it to five times. This also applies to repetitions. You need to start with two or three, and then increase the pace.
