Inversion of ankle with towel

Move the foot and ankle in the required direction without collapsing the arch or compensating at the knee. Complete the range with moderate, controllable tension. Keep the same range from repetition to repetition instead of speeding up as you fatigue. Breathe continuously and end the set before technique starts to break down.

Choose a resistance that lets you preserve technique from start to finish. You should feel most of the work in feet and ankles; if you feel sharp pain, joint pinching or a clear loss of control, reduce the load or range and stop if symptoms persist.
