Barbell Squat with Heels Raised Guide
 1.Place  a barbell on your upper back with an overhand grip. Squeeze your  shoulder blades together and tighten your abdominals to maintain core  stability. Stand with your feet shoulder-width apart and place heels on a  pair of five-pound weight plates resting on the ground.
2.Bend  your knees and sit into a squat by lowering your hips. At the bottom of  the position, your knees should be about 90 degrees with thighs  parallel to the floor. Maintain an upright posture. Pause for a second  at the bottom and then explode upward to the starting position pushing  through your heels
