How to: Balance on 1 leg, perform a quarter single leg squat, as you come up hug the opposite knee into your chest. Stand tall with the balanced leg completely straight. Engage the glute & draw-in your navel. Hold for 3 sec. and repeat in a marching fashion for prescribed sets, tempo & reps.
Compensations: Watch for rolling the ankle outward, rushing the movement, not engaging your gluteal of the balanced leg.
