Sit on a bench or chair and anchor a resistance band to a sturdy object behind you. Loop the other end around one ankle. With your torso upright and core engaged, bend your working knee to curl your heel toward your seat against the band’s resistance. Slowly return to the starting position with control while maintaining tension on the hamstrings throughout the movement. Complete all reps on one side before switching.
