Stand next to a counter and hold on with one hand. Move your weight onto your operated leg and lift the other foot a little off the floor. Keep the knee of the standing leg soft, not locked. Hold for the time shown, then rest. As it gets easier, hold on with your fingertips only.
If an exercise hurts more than you expect, stop and contact your clinician.
