Crunches performed with double-row support bars provide heel stability for a more effective and balanced workout to support core strength development.

Thick, contoured, non-slip, cushioned high-density foam padding offers comfortable foot or ankle support, while reinforced nylon webbing ensures durability for long-term use.

Simply adjust the strap, place the device under a door, close the door securely, and insert your foot or leg to begin your sit-up exercise routine. Easy to Carry & Store: When not in use, the leg training straps can be rolled up and stored in backpacks, suitcases, or small spaces. Lightweight and portable, it is convenient to carry to dorms, offices, hotels, or other locations, allowing you to maintain your fitness routine while traveling.
