I bought this along with my Hyper Z since it is more specific to stretching lower back than the strap This is as well designed + bilt as the mach of the highest standard The quick release is very convenient and easy to install. The only slight criticism I have of this set up is that the Weight Posts do not fit flush over the pendulum bar after installing the quick release. This results in the posts being slightly off center however this is insignificant to the function since the strap or the Hyperroller both have enough leeway so that when exercising any off center position of the weights is compensated for by that movement .

This piece has mixed reviews from our members. Some find it pushes them forward on the up-swing, even after adjustment, while others love it. Like anything it is expected that not everyone will enjoy, but overall, very satisfied with this addition to our reverse hyper.

To all the people giving this a bad review do some research! It is not meant for your legs to be parallel to the floor at any point in the movement. Louie Simmons is the inventor of this machine and he is the godfather of modern day powerlifting! He has videos on the internet about proper form! It works exactly the way it should and isolates the erectors! It's a five star item know what you are talking about!

As in my Z Hyper review, I bought this thinking the strap that comes with it would be uncomfortable on the back of the legs but it's not. However I would buy the roller again because it looks like the strap will work better for big plates and the roller for little plates. Plus I think the roller is more comfortable for my wife, Happy Wife... Rogue!!!
