One-Leg Bodyweight Box Calf Raise

Stand on a box (or stair step) with the balls of your feet on the box and your heels hanging off. Place your hands on a sturdy object or wall for support. Bend the knee of your non-working leg 45 to 90 degrees to lift it out of the way. From here, raise the heel of your planted leg by flexing your calf, elevating as high as you can. Hold the top for a one-count, then slowly lower down into a full stretch so that the heel of the working leg goes below the level of the box. Continue the pattern with a deliberate, controlled motion and deep stretches on every rep.
