Asymmetry, Unilateral Work, and the Limits of Bilateral Thinking in Strength Training

Human beings are asymmetrical. That is normal. There is no bilateral movement where both limbs produce exactly the same force. There is no athlete whose dominant and non-dominant sides are truly identical. Accepting that changes how training should be designed. Dr. Juris’s guideline for the lower body is practical: if one leg is more than 15 percent stronger than the other, address it. In the upper body, differences of 20 percent are common and not always concerning. The issue is not asymmetry itself. The issue is large, unmanaged asymmetry that creates compensation under load. Again, unstable-surface training reveals the problem. On a BOSU ball, the stronger leg tends to push harder. The surface distorts. The body responds to instability with compensation, and the exercise gets labeled balance training. In reality, it may just be reinforcing the imbalance. Unilateral work addresses this more directly. Split squats, single-leg deadlifts, and single-arm presses train the body the way it actually functions. One side takes the demand. One side controls the load. Weakness has fewer places to hide. For coaches and operators, that means unilateral training is not a trend. It is often a more honest way to assess and improve function.
