Position shoulders and upper back on a flat bench and hold barbell across hips just below the bone. Place feet flat on floor hip-width apart and lower your glutes until they almost touch the floor. Press your hips straight up, pausing at the top before slowly lowering to the start and repeating right away. Tip: Drive through your heels to make this glute-intensive. You can also change the position of your feet — closer, farther, toes straight, toes out — to change the emphasis on the glutes.
