What is the Left-Right Balance & Symmetry Test?
Most people are stronger or more mobile on one side. This test uses your camera to measure it. Choose single-leg balance (hold time and sway for each leg), squat symmetry (left and right knee angles and sideways hip shift), overhead reach (how high each arm goes) or push-up symmetry (left and right elbow bend).
You get a clear left-vs-right result with the percentage difference, a plain-English verdict and exercises to correct the weaker side. Small differences are normal; larger ones are worth working on.
