Sumo squat: Similar action as above, but stand with your feet wide apart.
Plié (Inner Thigh) Squat: Stand with your feet wide apart, toes pointing out (away from each other). Perform bending action as regular squat.
One Leg Squat: Same as regular squat, only using one leg.
Wall Squat: Stand with back to the wall, perform a regular squat into a sitting position and hold for 30-60 sec. as 1 rep.
Things to Remember1. If you can, go down until your butt is in line with your knees (knees at 90 degree angles). If you can't go down that low, go as low as you can.
2. Make sure your knees are BEHIND your toes.
3. Keeping the weight in your heels, slowly push your body back to starting position.
