How to do it

  1. 1
    Set up

    Same setup as the two-leg version, one shin behind the pad.

  2. 2
    The cue that matters

    One leg at a time exposes the weaker side - match the reps to the worse leg.

  3. 3
    Work it

    3 sets of 12-15, resting about 1 minute between them. Both sides, same number of reps.
