Once you master the reverse lunge, you can increase the exercise’s difficulty by standing on
a step, sturdy box, or short table that is approximately 6 to 10 inches (15-25 cm) high. The
same rules apply, but this variation will increase your hip range of motion and provide a
greater stretch to the working glute. Beware the following day. This exercise may impair
your ability to sit down without appearing like an old man or woman. In other words, the
stretch loading on the hips can produce serious glute soreness.
