Heavy duty and fully adjustable, the BLK BOX 45 Degree Hyperextension is a vital but understated piece of training equipment. It can be used to strengthen lower back muscles for peak sporting performance, whilst also easing or preventing spinal issues. Dual foot rollers clamp feet in place comfortably, while allowing you to steer you into the perfect angle. Both thigh pads and ankle rollers are fully adjustable, with seven heights available on the feet pads, and nine on the thigh supports. Laser-cut steel offers stability and durability, while rubber grip handles allow the user to self-spot.
