Single Leg Hamstring Bridge

Start by lying on your back with your knees bent and on a bench or box, hip-width apart. Extend one leg straight out, keeping your foot off the box. Press through the heel of the foot that remains on the box and lift your hips toward the ceiling, squeezing your glutes and hamstrings at the top. Keep your core engaged to avoid arching your lower back. Slowly lower your hips back down to the floor with control, and repeat for the desired reps. After completing the set on one leg, switch to the other leg.
