A traditional Reverse Hyper uses a loaded pendulum and pulls the back into spinal decompression. Bodyweight or banded Reverse Hypers such as on the Freak Athlete Hyper do not pull the back through spinal decompression. The focus and tension is on the top portion of the movement when the body is extended. This movement brings a ton of blood flow in to help strengthen the posterior chain with minimal risk of injury. With the GHD Attachment, you can train through a full range of motion if you are 6' 6" or shorter.
