Muscle Asymmetry And How To Fix It

In the context of beauty, aesthetics and performance, symmetry is one of the most important considerations in your goal to optimal fitness. However, due to the fact that people always tend to use one side of their body more, asymmetry occurs often. There are ways around it, so in this article we’ve decided to give you insight on how to fix any asymmetry in your body.

What Is Asymmetry?

By broad definition, asymmetry is the imbalance between two sides of the body. When it comes to measurements, symmetry is directly tied to beauty in anthropometry (the science that deals with the measures and proportions of the body).

This is due to the fact that there are ratios and measurements that can be used to describe an aesthetically pleasing body figure. Nevertheless, asymmetry is NOT just about looks, as muscular asymmetry can be further classified into two subcategories:

  1. Visual asymmetry
  2. Functional asymmetry

The first one, visual asymmetry, is basically the imbalance in the sizes of the two sides of the body (i.e one of your arms is bigger/more defined). On the other hand, functional asymmetry is the imbalance in the physical properties of both sides (i.e one of your arms is stronger)

Oftentimes, one leads to the other but that is not valid a hundred percent of the time, as in some cases, the smaller arm can be the stronger side.

Placing The Goals

Placing The Goals

In the context of developing an aesthetically pleasing physique that performs well and isn’t at a risk of injury, there are a couple of goals to set down:

  1. Achieving functional symmetry

Functional symmetry is achieved when both sides of the body are working in synergy and have the same strength output, strength endurance, mobility and flexibility

  1. Achieving visual symmetry

Visual symmetry is achieved when the ratios and measurements of the lengths and shapes of the muscles, are identical

The Approach

If your asymmetry wasn’t a product of a harsh injury, such as a torn muscle, there are things you can do to even out the size and strength of both sides.

Here are our best tips to help you bring up your weaker sides!

  1. Exercise form


On many exercises, we tend to use the stronger side of the body more, which results in a crooked range of motion and uneven tension. When doing any exercise, try and make sure that both sides are on the same plane and that you do not use any inertial movements (cheating).

Try and apply constant tension on the muscles that are working, through a moderately paced range of motion.

  1. Prioritize!

Whether you are trying to bring up asymmetrical sides of your body, or just bring up generally lacking muscle groups, prioritizing those parts of your body is one of your best bets. To prioritize a muscle group, increase the total training volume (number of sets and reps), but also increase the weight and time under tension, as well as the frequency of training.

An important note here is that you should be doing this for the asymmetrical muscle group, ON BOTH sides – Don’t just increase the output on one side!

  1. Exclude certain exercises

In many cases, individuals have overdeveloped muscle groups that prevent them from properly targeting certain lacking muscle groups. For instance, if your triceps are too developed, they would absorb most of the tension during pushing exercises, robbing you of solid chest and shoulder work.

In that case, bringing tricep work down to a minimum would be a good idea, along with including isolated exercises for the lacking muscle group.

Balance Is The Goal


Whether you are a professional athlete or a regular gym trainee, optimal symmetry should be one of your first checkpoints on your way to good fitness. This is especially valid for competitive athletes, as achieving such balance would allow you to focus on what the specific sport requires, rather than focusing on bringing up weaknesses.


By nature, the human body is NOT perfectly symmetrical, so even if you take a picture of half of your body/face and flip it horizontally to make it into a full body picture… It wouldn’t look natural!

In that context, you shouldn’t really aim to achieve perfection, rather than a fairly decent visual and functional balance. Use the right exercise technique and constant tension, while building your routine around your weaker body parts, to prioritize them.
