Heavy duty and fully adjustable, the BLK BOX 45° Hyper Extension 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 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.

Using the BLK BOX 45° Hyper Extension offers the user to complete a hinge variation exercise in order to get adequate hip flexion and extension. Using this piece of equipment will strengthen the athletes posterior chain and can be used as an assistance movement to improve the squat and deadlift totals.

Manufactured from start to finish at BLK BOX HQ, the BLK BOX 45° Hyper Extension incorporates the use of locally sourced laser-cut mild steel. This laser-cut steel offers stability and durability for the user throughout the entire duration of their workout. All steel is laser-cut on-site, before being welded, powder coated and assembled. A large number of parts are welded using robotic welding, while some parts require the detailed touch of our in-house welding team.

The high-density foam used on the 45° Hyper Extension offers the athlete a firm and stable cushioning throughout their exercise. High density foam padding features a highly durable vinyl leather cover, and offers a comfortable, firm and secure experience for the user. It can be easily wiped down and cleaned when necessary. 

The BLK BOX 45° Hyper Extension is coated in our signature textured anti-scratch powdercoat finish. It enters our internal industrial paint line, going through various stages of washing, drying, and painting before coming out freshly baked.

The 45° Hyper Extension also features rubber grip handles which allow the user to self-spot.
