Strengthen Ankle, Knee & Hip Stability With Unilateral Coaching
Holding a steady 10-to-30-second single-leg stance depends on gluteus medius strength, foot-ankle proprioception, and hip alignment.

Frequently Asked Questions
Why is single-leg balance considered a biomarker for longevity?
A landmark study published in the British Journal of Sports Medicine (BJSM 2022) found that inability to hold a 10-second single-leg stance in mid-life was associated with an 84% higher risk of all-cause mortality over a decade.
What is the proper testing protocol?
Stand barefoot on a firm, flat floor with hands on your hips. Lift one foot off the ground without allowing it to touch the standing leg. Stop the timer if the raised foot touches down, the standing foot moves, or hands leave hips.
What degree of asymmetry between legs is normal?
A difference of less than 15% between your left and right sides is normal. Asymmetries exceeding 20% often suggest gluteus medius weakness or previous ankle ligament laxity.
