You can do this move unsupported or, to modify, sit back onto a chair or bench.
How to Do a Single-Leg Squat:
- Stand with your feet hip-distance apart and raise your right leg just off the floor, flexing your ankle to point your toe toward the ceiling.
- Bend your left knee and sit your hips back into a one-legged squat. Try to keep your knee behind your toes and your whole foot pushing firmly into the floor. Make sure to activate your core by gently pulling your abs toward your spine.
- Lower as far as is comfortable, or to sit onto a chair or bench.
- Hold for a beat, then press into your standing leg to return to the starting position. That's one rep.
- Do three sets of five to eight reps, then repeat on the other side.
