Ring Hamstring Curls are an effective exercise for targeting the hamstrings using gymnastics rings. To perform this exercise, start by lying on your back with your heels placed in the rings. Your body should be in a straight line from your shoulders to your feet. Engage your core and glutes, and then curl your heels towards your glutes by bending your knees. Keep your hips elevated throughout the movement to maintain tension on the hamstrings. Slowly return to the starting position and repeat. Focus on controlled movements to maximize muscle engagement.
