1. Enhance your at-home leg workout anytime, anywhere - The 3rd generation dumbbell foot attachment is lightweight and space-saving, making it perfect for home gyms, physical therapists, personal trainers, athletes, or people with an active lifestyle. It's a great alternative to bulky machines like leg curls, extension machines, and monkey feet. Its portable design makes it easy to perform weighted leg exercises such as leg curls, kick-backs, fire hydrants, and clam raises. 2. Build leg muscle tone and strength - This foot dumbbell attachment converts dumbbells into ankle weights, seamlessly incorporating weight training into your leg workout routine. It effectively works key muscle groups, including the glutes, hamstrings, quadriceps, and hip flexors. By applying weights to your feet, you can easily perform machine-equivalent movements and a variety of other movements. 3. Tibialis Anterior Trainer - This accessory can be used as a tibial bar or tibialis dorsi trainer to effectively work your calf muscles. It strengthens the tibialis anterior, knees, and ankles, improving vertical jumps and running speed while enhancing balance and potentially reducing post-exercise discomfort and the likelihood of ankle and foot injuries. Unlike traditional tibial bars, it stretches the foot 360 degrees, allowing the tibial muscle group to develop more flexibly. 4. Safe and Comfortable - Carefully crafted by professional rehabilitation trainers, this ankle strap features reinforced stitching and is made from the same material as your car's seat belts. It can securely hold up to 110 pounds of dumbbells for leg raises or weighted barbell hangs (or up to 55 pounds of dumbbells for leg curls or donkey kicks). The strap is easy to use and easily adjusts to your foot weight.
