Lie on an exercise bench with your lower back pressed against the bench. Place your hands underneath your glutes. Hold your legs straight out with the knees straight and point your toes. This is the starting position. Slowly, pull your knees towards your chest until your glutes start coming off the bench. Exhale during this movement. Slowly return to the starting position. Inhale during this movement. Repeat for the recommended number of repetitions.
