In one sentence, describe what the following article is about: The hamstring curl machine will have stacked weights on one side, a flat bench for your body, and a padded cylinder for you to move with your legs. Laying on your stomach, the padded cylinder behind you should go on top of your legs. The pad should hit just a few inches below your calf muscles. You can adjust it using the lever until it is in the right spot for your height. Tighten your core muscles to help you keep your torso flat on the bench. Ensure your legs are fully stretched in the starting position, and grab the handles in front of your shoulders to steady yourself. As you breathe out, curl your legs up as far as possible without lifting your upper legs off of the bench. Hold for a second once you reach the fully contracted position. If it is too easy or too hard, you can stop and adjust the weight using the stack next to you. As you breathe in, bring your legs slowly back down to your starting position. Repeat for recommended amount of repetitions.
Summary: Find the machine. Adjust the lever. Keep your torso flat. Exhale and curl. Inhale and release.
