Movement: Maintaining stability in your off leg, raise the heel of your working leg behind you towards your butt. Focus on engaging your hamstrings to initiate the movement, and pause at the top of the movement to focus on the contraction. Return to the start position under control.
Repetitions: Perform all prescribed reps on one side, then on the other. This counts as one set.
Assists: Holding onto a railing or sturdy door can be used to make the exercise easier, especially if stability is a problem.
