Leg Curl Variations (KNOW THE DIFFERENCE!) If you point your toes inward on the leg curl, you'll target the semitendinosus and semimembranosus. If you point your toes outward, you'll target the biceps femoris long head and short head. If you point your toes up, you'll work the hamstring muscles evenly. If you lean forward, you'll work the hamstrings in a stretched position, which is superior for growth. Size & Shred Training program 👉🏻 deltabolic.com | Andrew Kwong
