Have you noticed that one side of your body feels different from the other?
Perhaps one hip feels tighter. One shoulder seems more restricted. Balance feels easier on one leg, or one side feels stronger during exercise.
Although the body is often described as symmetrical, human movement is rarely perfectly symmetrical.
The more useful question isn’t necessarily “How do I make both sides the same?”
It’s “Why are they different, and how are those differences affecting the way I move?”
The body isn’t perfectly symmetrical.
The body has a basic left-right symmetry, but the two sides don’t always function identically.
Movement preferences develop over time. One leg may be favoured when standing, the same shoulder used to carry a bag, one leg crossed more often, or one direction found easier to turn towards.
Sport, work, previous injuries and everyday habits can all contribute to differences between the two sides.
Ageing can also change how the body moves. Joint stiffness, reduced strength, changes in balance or conditions such as knee degeneration may lead to greater reliance on one side.
Even anatomy isn’t perfectly symmetrical. Some degree of difference is completely normal.
The important question is whether the difference is simply a variation or whether it’s affecting movement adversely.
Stronger doesn’t always mean better. It can be tempting to assume that the stronger side is doing a better job.
But strength is only one part of movement.
Mobility, stability, coordination, balance and control matter too.
A stronger right leg, for example, may not be working more effectively. It may be taking over because the left side is painful, stiff or less able to contribute.
This is one reason the pilates method isn’t simply about strengthening individual muscles. The focus is how the whole body works together.
What happens when one side starts compensating?
The body is remarkably good at finding ways to maintain its movement capability.
If one area isn’t contributing effectively, another area may take over.
You might notice:
The movement may still look functional.
Over time, however, repeated compensation can become the body’s preferred way of moving. This may be especially noticeable after an injury or when living with ongoing joint changes, such as knee degeneration.
That’s why an experienced pilates teacher isn’t only looking at whether you can perform an exercise.
The focus is also how you perform it.
Pilates creates an opportunity to slow movement down and develop awareness.
Rather than simply completing a set number of repetitions, attention can be given to what is happening throughout the movement.
Can weight be distributed evenly? Can the pelvis stay aligned while the legs move? Does one shoulder move differently from the other? Can rotation happen comfortably in both directions? Does one side need to work harder to stabilise?
These observations provide useful information.
An exercise can then be adapted to the individual rather than assuming that everyone should perform it in exactly the same way.
The aim isn’t to force the body into perfect symmetry.
Every body has its own history, structure and movement patterns.
Instead, the aim is to develop greater awareness, control and efficiency of movement.
That might mean strengthening one side more than the other, stretching one side more than the other, standing on one leg more than the other for balance.
Sometimes the most useful step in your journey is simply recognising a movement habit that has developed over time.
During an exercise, your teacher may notice things that aren’t immediately obvious.
Perhaps the pelvis shifts when one leg moves. Weight may move onto one foot. One shoulder may consistently take over.
These aren’t necessarily “mistakes”.
They’re information.
They help reveal how the body is organising movement and whether an exercise needs to be changed, slowed down or approached differently.
This is one of the strengths of the pilates method: the exercise can be adapted to the person rather than expecting the person to fit the exercise.
Should you be concerned if one side feels different?
Not necessarily.
Some asymmetry is normal.
But if a difference is new, becoming more pronounced, associated with pain, weakness, numbness or a significant change in function, it’s worth having it assessed.
For everyday movement, noticing differences between the two sides can simply be an opportunity to become more aware of the body.
Next time you’re in class, notice:
Which side feels easier? Which side feels more stable? Which side do you naturally rely on?
You may discover that your body has been communicating something you’ve never noticed before.
The pilates perspective?
Perfect symmetry isn’t the goal.
The aim is to understand how the body moves and support greater awareness, control and confidence, whatever its history, age or physical changes.
