When you do hamstring curls, you build the muscles on the back of your thighs. You can try these five types of leg curls:
1. Machine Hamstring Curl
Place your legs under the padded lever of a leg curl machine. Bend your knees to raise your legs, then lower them slowly.
2. Standing Hamstring Curl
To balance, stand erect and grab onto anything sturdy. Lift one leg behind you, bending your knee and bringing your heel to your buttocks. Lower it and repeat on other leg.
3. Swiss Ball Hamstring Curl
On your back, place your feet on a Swiss ball. Bring your hips up, bend your knees, and roll the ball towards you with your heels. Repeat with extended legs.
4. Dumbbell Hamstring Curl
Lay facedown on a bench with a dumbbell between your feet. Flex your knees to elevate the weight to your buttocks, then lower it without contacting the floor.
5. Single-Leg Hamstring Curl
Use a cable machine with ankle straps. Stand facing the machine, strap one ankle, and pull your leg behind you against the resistance, bending at the knee. Lower it and flip sides.
