You can do any of these 10 moves in your living room, without weights.

1. The Perfect Squat

Go low: Drive butt back (as though sitting on a chair), keeping thighs parallel to floor and knees over toes.

Get grounded: Position feet shoulder-width apart and slightly turned out with your weight on heels. You should be able to wiggle toes.

Open up: Place hands behind head. Lift chest, and draw shoulders back and down.

Stay in line: Keep a neutral spine without arching your back; engage your stomach.
