As part of our workout Metabolic Effect post with Steve he recommended doing squats as part of a combination of moves (including a pull-up) and here he breaks it down for us:
Stand with your feet shoulder width apart and toes pointing straight forwards.
Keep the back straight as you initiate movement at your hips.
Push your buttocks out behind you and bend your knees, starting with shallow squats and increase gradually.
Return to the starting position.
