HOW: In a seated position, loop a band around the balls of your feet. Push one foot out to the side using no tension. With the opposite foot, pull the band back across creating tension in the band while the other foot is holding that resistance out to the side. Slowly, control your foot going back inwards.
FEEL: You should feel your lower leg muscles working.
COMPENSATION: Don’t move your knee, only have motion in your foot/ankle.
