Exercise Equipment: The hamstring curl band is the perfect waist and abdominal exercise equipment to allow you to practice better sit-up form by placing your feet on the floor and maximizing activation of your core abdominal and hip flexors. Ergonomic Design: The high-density soft foam covering handle is comfortable and non-slip while avoiding ankle injuries. Crunches with double-row support bars strengthen your heels for a more efficient and balanced workout to help you get in perfect shape. Stable and Comfortable: A really sturdy sit-up aid! The center bar of the hamstring curl band is made of steel for maximum stability and control. Thicker, curved, non-slip, cushioned high-density foam padding provides comfortable foot or ankle support, and thickened nylon webbing ensures long-time use. Adjustable Straps: The hamstring curler is easy to use and allows you to adjust the straps for a better fit or comfort. Just adjust the strap when use, place this device under the door, close the door and insert your foot or leg so you can quickly enjoy your sit-up training. Easy to Carry & Store: When not in use, the leg training straps can be rolled up and stored in backpacks, suitcases, and do not take up much space. Easy to carry to dorms, offices, hotels and other places. So you can train even while traveling.
