Circuit Three: Wall Sit
- Stand with your back against a wall, placing your feet about two feet out in front of you. Feet should be hip-width distance apart.
- Bending your knees, slide your back down the wall until your knees are at 90-degree angles. Your knee joints should be over your ankle joints, so you may need to inch your feet further from the wall to create proper alignment. Don't let your knees fall in toward each other or sway outward.
- Hold for 30 seconds.
