Lie on your back with your feet flat on the ground, heels just below your butt. Grip the middle of the resistance band, with your hands about shoulder-width apart, and place it over your hips.
While pressing the resistance band into the ground on each side, push your hips up toward the ceiling, squeezing your butt at the top of the move.
Hold for one to three seconds before returning to the starting position for one complete rep.
