If building and strengthening the lower back and core is the question, the answer is the Hyper Back Extension. Combining the efficiency and effectiveness of bridges, Supermans, pelvic tilts and more ground-based, back-focused exercises, the Hyper Back Extension works the erector spinae, a group of small muscles that connect to the pelvis, vertebrae and ribs and which runs the length of the spine. Back extensions also work the muscles in your core, butt, hips and shoulders. All of which is designed to strengthen the lower back and core muscles which aid in the management of back pain, offer support to the spine and improve posture. A productive and safe workout on the Hyper Back Extension begins with the correct alignment of the height-adjustable thigh pads. For best results, users should ensure the top of their hips meets the top of the thigh pads. The pad digging into the stomach is the first indicator that the user is positioned incorrectly. The Hyper-Back Extension features a 45? angle, which is ideal for beginners and intermediate users of the machine. Assist handle, which maximize lower back and abdominal workouts are also included. They're also great as users get initially accustomed to the machine, they can hold the assist handles for support. However, once accustomed to the movement, the assist handles should be used less frequently. Want to work the neck extensors, a small but key muscle situated at the back of the neck that aids in neck mobility? Place the hands at the back of the neck when doing the hyper-extensions. To add some difficulty and additional resistance to the exercise, hold a weight plate, dumbbell or kettlebell while doing it. Please note this is the Hyper Back Extension only. Weight bars, weight plates, dumbbells and all other accessories are available separately. While assembly is required for the Hyper Back Extension, no power tools are needed to put this unit together. Nine different height adjustments are available depending on user comfort, preference and ability. The convenient footprint of 32" x 49" means the Hyper Back Extension can fit nearly anywhere. Y-shaped base is sturdy, secure and won't wobble. Easy to clean needing just a warm, damp cloth and some mild soap.
