Start Position:
  1. Wrap the resistance band around an object that is not going to move such as a pole, fence, tree or something similar and create a loop. The resistance band should be close to the floor.
  2. Lie face-down with the band looped around one of your heels. Move far enough away from the anchor point so that the resistance band has tension with your leg straight.
  3. As you bend, maintain your knee in line with your foot.
End Position:
  1. Lying face-down with the band looped around one of your ankles and your leg bent
Action:
  1. Bend your leg at the knee moving your heel as close to your buttock as possible.
  2. Then, straighten your leg back to the start position and repeat.
  3. Once you have completed your set on one side, repeat on the other side.
Modification Options:
  1. Vary the strength or length of the resistance band used to increase/ decrease the difficulty of the exercise or shorten the loop being used to increase the difficulty.
