Lie face down on a mat with your legs extended. Bend your knees and reach back with your hands to grasp your ankles or heels. Use a gentle pull with your hands to assist your hamstrings as you curl your heels toward your glutes, then slowly lower your legs back to the starting position with control. Focus on engaging the hamstrings throughout the movement while keeping your hips and core stable.
