This lunge variation really works your butt and thighs:
- Begin by placing the top of your left foot on a sturdy chair, keeping your right leg straight.
- Bend your right knee, engage your left glute, and lower your pelvis toward the ground. Your right foot should be out far enough so that when you lower your hips, your knee stays directly over your ankle.
- Straighten your right leg and rise back up to the starting position. This is one rep.
- Complete two sets of 10 reps on each leg.
