Start by securing a thick resistance band low behind you.
Place your foot on a step and squat down in half-kneeling.
Place the band around your ankle as low as possible and move further away from the insertion to take the slack off the band.
This is your starting position.
Then bend your ankle further by moving your weight forwards and pushing your knee over the toes.
Keep your heel on the surface.
Then slightly relax without returning all the way back to the starting position and repeat.
