The size of a muscle depends primarily on its activity. Muscle develops in response to stress, and if your profession is more active on one side of the body, then the muscles on that side may become slightly larger. For example, a blacksmith who holds a hammer in one hand all the time, or athletes - fencers or tennis players.

With the wrong exercise technique, one part of the body will also receive a lot of stress, which will lead to uneven muscle development.

When the pectoral and spinal muscles appear inharmoniously developed or after an injury, when the limb is immobilized for a long time and the muscles in it have atrophied.

In all the above cases, correction of the less developed muscle is required.

How to train with different muscle sizes

First of all, the load during training should be equal on the left and right side of the body. The number of repetitions for the right and left sides must be equal.

If you lift or crooked, an uneven load will be provided. It is necessary to strictly adhere to the technique of performing all exercises and to control yourself with the help of a mirror.

Some people make the mistake of noticing uneven muscle development and taking on more weight on the less developed side of the body. You can't do that.

In this case, the technique of the exercise is violated and the wrong skills develop, which can lead to a banal injury. In addition, there is no point in overloading one side: the weaker muscle will not lift a heavier load, and the stronger muscle will not work enough. Here it is important to follow the correct technique in training and to load the muscles in the same way, then they will begin to develop proportionally.

If the deviations in the proportions of the muscles are very strong, you can use additional for the lagging muscle group. That is, after the end of the exercises for a certain muscle group, an additional approach should be performed on the lagging side.

There is no need to overload the muscles with unnecessary approaches, one extra will be enough, otherwise you risk, they will not recover properly, and the next workout the overloaded side of the body will work even worse.

Use dumbbells or exercise machines to add muscle tension to only one side of your body. For example, take dumbbells in both hands (for balance and proper exercise), but press with only one hand.

Special exercises for one side can be chosen for each muscle group, but it is worth resorting to them only with a pronounced imbalance. Recovering atrophied muscles after an injury also requires additional approaches and exercises, in other cases you need to train evenly and regularly, loading the muscles equally.

By using the right ones and exercising consistently, you can achieve harmonious muscle development and symmetry.

The baby's first movements are due to the musculoskeletal sensation with which the baby, long before birth, determines its place in space. In the first year of life, the musculoskeletal sensation gives the child a powerful stimulus for development. Thanks to it, the baby learns to make conscious movements (raises his head, reaches for a toy, rolls over, sits, gets up, etc.). And the main characteristic of the muscular skeleton of newborns is the tone.

The tone is different

Together we will try to understand what is muscle tone what is considered normal. Even in sleep, our muscles do not relax completely and remain tense. This minimal tension, which continues in a state of relaxation and rest, is called muscle tone. The smaller the child, the higher the tone - this is due to the fact that in the beginning the surrounding space is limited by the uterus and the child does not need to perform targeted actions. In the embryonic position (with tightly pressed limbs and chin to the body), the fetal muscles are in strong tension, otherwise the child would simply not fit in the uterus. After birth (during the first six to eight months), muscle tone gradually weakens. Ideally, the muscle tone of a two-year-old should be approximately the same as that of an adult. But virtually all modern babies have problems with tone. Poor ecology, complications during pregnancy, stress and a number of other unfavorable factors provoke a violation of tone in newborns. There are several of the most common disorders of muscle tone.

  • Increased tone (hypertension).

    The child looks tense and shrunken. Even in sleep, the baby does not relax: his legs are bent at the knees and tucked up to his stomach, his arms are crossed over his chest and his fists are clenched (often in the shape of a "fig"). With hypertension, the baby holds his head well from birth due to the strong tone of the occipital muscles (but this is not good).
  • Decreased tone (hypotension).

    With decreased tone, the child is usually lethargic, moves small legs and arms and cannot hold his head for long. Sometimes the child's legs and arms are extended at the knee and elbow joints by more than 180 degrees. If you put the child on his stomach, he does not fold his arms under his chest, but dissolves them to the sides. The child looks lame and sprawled.
  • Asymmetry of muscle tone.

    With asymmetry on one side of the body, the tone is higher than on the other. In this case, the child's head and pelvis are facing the tense muscles, and the body is bent in an arc. When the child is placed on his stomach, he always falls to one side (where the tone is enhanced). In addition, asymmetry is easily detected by the uneven distribution of the gluteal and femoral folds.
  • Uneven tone (dystonia).

    In dystonia, signs of hyper- and hypotension are combined. In this case, the child has some muscles too relaxed, while others are too tense.

Diagnosis of muscle tone

Usually, immediately after birth, the doctor, based on visual diagnostic tests, detects disorders of the tone and motor activity of the newborn. In addition, all infants have so-called "residual" (isotonic) reflexes, which can also be used to determine disorders of muscle tone. In principle, you can check for yourself how the child is coping with the tone. Here are some basic tests that can determine abnormalities in the development of muscle tone and postural reflexes in the newborn.

  • Breeding the thighs.

    Place the child on his back and carefully try to straighten the legs and spread them apart. But do not use force and make sure that the child is not injured. You should usually feel moderate resistance. If the newborn's legs, without resistance, are fully extended and easily separated in different directions, this is evidence of reduced tone. If the resistance is too strong and at the same time the child's legs are crossed, this is a sign of hypertension.
  • Sitting on his hands.

    Place the baby on its back on a hard, flat surface (such as a changing table), grasp the wrists, and gently pull toward you as if sitting down. You should usually feel moderate resistance when stretching your elbows. If the child's arms are outstretched without resistance and in a sitting position the stomach is strongly protruding forward, the back is rounded and the head is tilted back or lowered, these are signs of decreased tone. If you can not remove the baby's arms from the breast and straighten them, on the contrary, it shows hypertension.
  • Step reflex and support reflex

    Take the baby vertically under the arms, place him on the changing table and tilt him slightly forward, forcing him to take a step. Usually the child should be leaning on a full leg with outstretched toes. And when he leans forward, the child imitates walking and does not cross his legs. This reflex gradually disappears and practically disappears within 1.5 months. If the child is over 1.5 months old, this reflex continues, this is evidence of hypertension. Also, increased tone is indicated by folded toes, crossing the legs when walking or supporting only the front of the foot. If instead of standing, the newborn squats, steps on strongly bent legs or refuses to walk at all, these are signs of decreased tone.
  • Symmetrical reflex.

    Place the baby on his back, stick your palm under the nape of his neck and tilt the baby's head slightly towards the chest. He should bend his arms and straighten his legs.
  • Asymmetric reflex.

    Place the child on his back and slowly, effortlessly, turn his head to the left shoulder. The child will take the so-called swordsman position: he will stretch his arm forward, straighten his left leg and bend his right leg. Then turn the child's face to the right and he should repeat this position only in the opposite direction: he will stretch his right arm forward, straighten his right leg and bend his left.
  • Tonic reflex.

    Place the baby on his back on a hard surface - in this position the tone of the newborn's extensor increases, he tries to straighten his limbs and seems to open. Then turn the child on his stomach and he will "close", will pull the bent arms and legs under him (the tone of the flexors increases on the stomach).
    Usually symmetrical, asymmetrical and tonic reflexes are moderately expressed and gradually disappear within 2-2.5 months. If the newborn does not have these reflexes or are too weak, it shows reduced tone and if these reflexes last up to three months, it is a sign of hypertension.
  • Moreau and Babinski reflexes.

    Observe the child carefully. In case of excitement, he should throw his hands aside (Moro reflex), and when the soles are irritated (tickling), the child reflexively begins to unfold the toes. Usually, Moreau and Babinski's reflexes should pass by the end of the 4th month.

If the muscle tone and related reflexes do not change according to the age of the baby, this is a very dangerous signal. Don't rely on the infamous "maybe" and expect the muscle tone problems to go away on their own. Impaired tone and the development of reflexes often leads to a delay in motor development. And with a strong deviation from the norm, we are talking about the possible formation of diseases of the nervous system, ranging from seizures to cerebral palsy (cerebral palsy). Fortunately, if the doctor diagnoses a birth defect (or in the first three months), the threat of developing serious diseases can be prevented with the help of massage, because in the first year of life the nervous system has a huge potential for recovery.

Causes of muscle irregularities 

  1. Congenital or acquired disease  . In this case, due to metabolic disorders or deformities in certain parts of the body, muscle disproportion occurs. That is, nutrients are not delivered to those parts of the body where it is needed, and there the muscles begin to "dry out". For example, diseases of the spine (scoliosis, kyphosis) - deform the spine, as a result of which the proportion of the body (muscles) changes.
  2. Physiological characteristics of right-handers and left-handers  . Because of these characteristics, the right uses the right arm or leg more often, and the left uses the left arm or leg (left side of the body) more often. That is why right-handers on the right side of the body will have a little more muscle than on the left side, and vice versa for left-handers. Hence the difference in muscle size. After all, each of us noticed that it is much easier for the leftist to lift some weight with his left hand, and for the right hand - with the right ...
  3. Characteristics of a profession or sport  . In this case, people who constantly load the same part of the body, as a result, get a difference in the volume of muscles in one or the ionic part of the body (muscle group). For example, a left-handed blacksmith who constantly holds (works) a hammer in his left hand will train the muscles on the left side much more significantly than in the right. The same is the case with tennis players or fencers. As you have already understood, this reason is very much related to the physiological characteristics of left-handers and right-handers (the second reason).
  4. Improper exercise technique  . The most unpleasant is when due to carelessness and inexperience the athlete neglects the technique of performing the exercises. Because when he does something wrong for a long period of time, he will gradually get an unpleasant result. At least there is a difference in muscle volume, and at most there is an injury.
  5. As a result of injuries  . None of us is protected from injury, as even a very careful and experienced athlete (employee) can get it. Thus, any injury leads either to impaired blood circulation (this reason is very much related to the first), or to a temporary restriction in movement or immobilization of the part of the body where the injury occurred. Thus, if the blood circulation is disturbed in one of the parts of the body, then the muscles will not develop evenly, as much less nutrients will flow to the damaged area through the blood. After all, one of the main conditions for muscle growth is good nutrition (oxygen and nutrients).

But, even if the injury leads to restriction of movement or immobilization of any part of the body, then in this place the muscles will begin to "dry out" (decrease) due to lack of training. After all, our body is the most greedy of all I know, because it always strives for balance and does not spend unnecessary resources to maintain systems that it does not need. In this case, it is an unused part of the body (muscle group). For example, a broken arm will significantly weaken it ...

How to be the one with the most noticeable difference in muscle volume

Of course, it is unpleasant to have a disproportionate body, but do not despair - everything can be corrected if you follow my recommendations, but first, let's analyze the main mistake that many athletes make on the way to a proportional body.

As you already know, the question is what to do if one pectoral muscle is bigger than the other? It can happen to any of us. But the worst thing is that many believe that if you give the lagging muscle an even greater load (weight), it will increase and therefore the proportion of muscles on both sides will appear. But everything is not as simple as it seems, because this method in most cases only leads to injury and overtraining (regression), because in fact most often everything happens as follows:

  1. The weak muscle (lagging) has already received a good load from your working weight, but if you load it even more, the exercise technique will disappear completely, which means that part of the load will not be taken by the target muscles, but by auxiliary muscles, tendons. and the stronger side of - for the curve of the exercise. Which can lead to injury.
  2. Due to the heavy loads on the weak muscles, more catabolic (stress) hormones will be released, which have a very harmful effect on muscle growth (destroy them).
  3. However, the weak muscle, due to the heavy weight on it, may not have time to recover before the next workout. Therefore, with each lesson, if this continues for weeks or months, your overtraining is guaranteed.

By the way, when it comes to injuries, thanks to them, many athletes have completed their sports careers. After succumbing to the temptation to do everything faster, they were forced to regret this decision for a long time ... Do not repeat this mistake: "The slower you go, the farther you will be."

It is necessary to follow the correct technique of exercise,  because if this is not done, then, as I said, part of the load will go not to the target muscles, but to the auxiliary muscles and the stronger side. This leads to muscle imbalance, as the load on them comes in different ways. That's why ordinary mirrors, which should be in the gym, help  to avoid such an incorrect exercise. Your teammates or a coach who, watching from the sidelines, will invite you can also help you work out the right technique. After all, everything is clearly visible from the side and the advice said in time will quickly correct the wrong exercise technique. But if you leave everything as it is, then later it will be difficult to correct what was missed, because the wrong skills (technique) are acquired.

You can take an additional approach after the basic exercises, but this is only for those who have a very noticeable difference in body proportion.

In practice, it looks like this. After completing the exercise for the target muscle group, do another approach, but only for that half of the body where the muscle is smaller.

However, it is worth ignoring this rule and you, the lagging country, may, on the contrary, start regressing against the background of non-recovery. Because the muscles are lagging behind, they will not have time to recover until the next workout.

Those who want to work on lagging muscles must use different machines and dumbbells.

For example, to increase only one pectoral muscle, try doing a dumbbell press while lying on your back. To do this, you need to take two identical dumbbells and lie down with them on the bench. Then start doing the exercise (lifting dumbbells upwards), but with only one hand. And the second dumbbell remains in its original position to maintain the balance of the body, because if this is not done, then it will be difficult to perform exactly the bench. Therefore, both dumbbells must be used, although the exercise will be performed with only one.

The same can be done with one hand on the machine used to train the chest muscles. At home, if dumbbells or other devices are not at hand, then the pectoral muscle can be trained with push-ups from the floor of one arm.

But the biceps can be trained in two main ways  :

(a) by means of a special bench which ensures bending only at the elbow joint, by means of a dumbbell;

b) the arm can be bent without the help of a special bench. To do this, use your thigh (with an emphasis on it) to completely exclude the work of other muscles. And this exercise is done with a dumbbell.

You can also choose exercises to develop any muscle on one side of the body only. But these additional methods (additional approaches to lagging muscles) should be used only in extreme cases when the difference in disproportion is very visible.

Exercise should be regular, but not every day. You should not expect success when lessons are held sporadically or only once a week (very rarely). With this approach, nothing will change in your appearance, as only regular exercise can  help you achieve results. After all, if you exercise less than twice a week, then it will not benefit your body to grow muscle mass. Therefore, I will repeat once again that only regular training and with equal load on both halves of the body align the muscles. You will learn more about the optimal number of workouts per week from the article:.

People who exercise or work out when they affect only one (most) of the body are also advised to include physical exercise in their workouts. But these exercises must be performed technically correctly and regularly, as only this will lead you to a proportionate body ...

As for the sets of exercises for general physical training, they have not yet harmed anyone, but on the contrary have helped to achieve better results and victories.

You can additionally train the part of the body that has lost muscle mass after a long illness or injury. However, before doing this, it is imperative, be sure to consult your doctor ... If there are no contraindications, then in any case, for this you should use only light weights and 1-2 additional approaches (after the basic basis for exercises) on the lagging muscle. But remember that everything should be moderate and gradual, therefore, listen to your body. And do not deviate from the basic rule: load the muscles evenly and lift weights technically correctly. In the end, it is then that gradually everything on your body will align and develop further evenly.

Do not chase weights, but chase the correct exercise technique, because you have to lift weights not by pulling, extra muscles, tendons, joints and other tricks, but by directing the muscles. This is why many professionals who lift weights properly do better than those who lift maximum weights. After all, if the neuromuscular connection between the brain and the muscles is well developed, then the muscles can be killed with very light weights, reducing them even to 40-60% (or even less) of non-working weights. were raised because of the technology, but because of other tricks.

And who understands this, begins to study the technique of the exercises and with horror notices that lifting a lot of weights, isn't it, not so easy. That is why it is necessary to monitor how you work from the first trainings and to pay maximum attention to it.

Of course, everything is understood with experience, but try to learn not from your mistakes, but from others ...

This technique has long been used by American athletes. Even based on this, you are already beginning to understand why they were the first to fly to the moon. Therefore, their training is not focused on maximum weights, but on the correct technique of execution in order to better work the target muscles (which need to develop). And as a result of this training you will not have imbalances in your body, that is, the muscles will develop harmoniously (proportionally).

A slight difference in the size of the muscles on one side and on the other is a completely normal thing that should not be feared. In addition, this difference is inherent in every person, the difference is only in size. But to correct a large imbalance or avoid it, it is necessary to train regularly, following the correct technique of exercise. I hope that now you will not have a question: What if one pectoral muscle is larger than the other, as well as other muscles located symmetrically to each other?

Do sports, eat right and get well - good luck!

Disproportionate development of symmetrical muscles is a common problem. In professional sports, this phenomenon is called muscle imbalance, which means asymmetric strength or volume of muscle mass on one side of the body in proportion to the other. Slight muscle asymmetry is characteristic of every person and within certain limits this is normal. But it happens that the sizes are strikingly different and this can be seen even with the naked eye. To eliminate such asymmetry, the reasons for it must first be understood.

Causes of muscle asymmetry

Mild muscle asymmetry is common in all people. In right-handers, the muscles on the right side of the body are most often more pronounced, as they perform most of the actions, and in left-handers - vice versa. This imbalance is subtle, but can be traced if measured. A significant difference in size occurs under the following conditions:

  1. With the peculiarities of the profession. If a person has to work with one arm much more than the other, then the muscles on the active side of the body become larger. This often happens among representatives of working professions - blacksmiths, carpenters, builders or professional badminton players, fencers.
  2. In the absence of competent exercise technique during training  . This is a biomechanical reason - if the training program is not built correctly, then one arm will be loaded more than the other.
  3. In various diseases and injuries . Muscle asymmetry often occurs in scoliosis due to curvature of the spine, when the muscles of the back or chest muscles may appear unevenly developed. In addition, the cause may be a neuromuscular imbalance due to the predisposition of certain muscle groups.
  4. If you have arms or legs of different lengths  . If a person's legs are of different lengths (and this happens quite often), then the body leans slightly towards the longer leg to compensate for the load. In this case, the left and right sides of the body develop unevenly.

The overall asymmetry is also different. It is most often present between the lower leg and arms, the biceps and triceps, the heads of the delta and the triceps.

How to deal with muscle asymmetry?

Muscle imbalance is most often detected immediately after starting a workout. It can be prevented or eliminated by reviewing the training program and taking into account some recommendations:

  1. Apply one-sided exercises  . It is advisable to add exercises on one side of the body to the approved program - this will make it possible to control the speed and technique of their implementation. If possible, you should turn off the simulators and include weight training in the program.
  2. Increase the number of repetitions  . It is necessary to maintain a balance of repetitions in accordance with the weak side of the body. The approach must start with a lagging hand and continue until it fails. The result of this approach will allow the lagging part of the body to develop and tighten.
  3. Observe the technique  . The competent form of exercise, taking into account the anatomical features of the athlete, will help to correct the asymmetry. It is imperative to warm up the muscles before starting the workout and cool down at the end of the session.
  4. Strengthen internal muscles and ligaments . To do this, it is recommended to include exercises for rotation with a dumbbell to strengthen the rotator cuff, side bends with a barbell on the shoulders, a barbell.
  5. Increase the strength of the weak side . When performing any exercise, it is required to increase the load on the weak muscles. If there is a strong imbalance, it is worth using additional approaches for the lagging arm or increase the number of repetitions for individual exercises.

So, hands of different sizes are an urgent problem for many bodybuilders. Every athlete, without exception, at a certain stage of muscle development and building, notices that a certain muscle group on one side of the body is obviously larger than on the other. If the imbalance is insignificant, this is perfectly normal, because all people have slightly different muscle sizes on the right and left sides of the body. In order to eliminate the noticeable asymmetry, it is necessary to adjust the training program.

The hands are the busiest part of the body, because it is with their help that a huge amount of work is done. As a result, the limbs are constantly overloaded, tired, broken and injured. Quite often the hands can hurt from the shoulder to the elbow.

If a person regularly lifts weights, then it is completely understandable why the muscles of the upper limbs hurt, because they do not have time to recover. The pain syndrome spreads from the forearm to the elbow. In addition, medicine knows the problems of the upper arms, which can cause discomfort not only in the joints of the shoulder, but also above. The patient cannot even move his elbow.
