One of the easiest and most effective ways to assess the body is by observing how a person moves on one leg. Most people develop a dominant side, and over time, that side often takes on a greater share of the workload. As a result, the non-dominant side may struggle with single-leg activities and compensate in various ways, often contributing less to the overall movement strategy.

A common compensation pattern occurs when the body cannot distribute the load evenly between both sides. In these cases, the pelvis will often shift toward the dominant side while the knee on the non-dominant side remains slightly bent. These compensations occur together, creating a posture and movement pattern that allows the body to continue functioning despite the imbalance.

If you have a moment, try a simple test. Close your eyes and notice whether one knee feels slightly more bent than the other. If it is difficult to tell, perform a single-leg squat from either a standing or seated position. In many cases, the side with the bent knee will also have more difficulty controlling the movement. Another assessment I like to use is a single-leg hop. While hopping side to side on each leg, most people notice a clear difference between the two sides. Not only will one side often feel weaker, but it will also appear less coordinated and less confident during the task.

The challenge, regardless of which side is struggling, is that the issue is often not a lack of strength. More commonly, the problem lies in how the brain organizes and controls movement on that side. The muscles may be strong enough, but if the body does not effectively load or trust that side, it will continue to shift work elsewhere. As a result, compensations such as a pelvic shift or a bent knee persist despite efforts to strengthen the area.

This is why many people continue to experience chronic pain, recurring injuries, and movement limitations even after spending years stretching, strengthening, and exercising. The missing piece is often identifying why the body has chosen that compensation pattern in the first place. Once the root cause is addressed, the body can begin to distribute load more evenly, allowing movement to become more efficient and less stressful over time.

When we see a bent knee, a pelvic shift, or difficulty balancing on one leg, we are not simply looking at a joint or a muscle. We are observing the body’s strategy for movement. Understanding why that strategy developed is often the first step toward creating meaningful and lasting change.
