Wall Squats 

Starting Position 
Stand facing away from a wall, with your back against the wall. Plant your feet 12" in front of your body with a shoulder width stance, toes pointing forward. This exercise can be used with or without dumbbells. 

Action 
Leaning against the wall, lower your body until your knees are flexed at a 90 degree angle. Hold this position for two seconds. Your weight should be on your heels, not your toes, and your knees should not cross the plane of your toes. Except to check your knee position, keep your head in a neutral position, looking straight ahead. Extend your legs to elevate your body back to the starting position. 

Special Instructions 
Don't lock your knees when you extend your legs back to the starting position.
