For our final exercise, a simple variation of squats that will help you to focus more on your glutes rather than your quads and hamstrings. By placing the weight BEHIND your body, the posterior muscles are engaged more efficiently. Your quads will still do a lot of the work, but it's your glutes that will really feel the burn.
Grasp the barbell behind your back. It should hang just beneath your butt, behind your legs. Point your toes outward, spread your feet shoulder width apart, and keep your upper body as straight as possible.

Drop slowly into the squat, lowering the weight until it nearly touches the back of your ankles/lower calves. You'll feel your upper body leaning slightly forward, but make sure that your back remains straight. Descend until your thighs are parallel to the floor, and clench your glutes and core as you stand back up.
Keep your shoulders back, your arms straight, your hips low, and your back straight throughout.
Repeat as desired.
