Check them out here:http://www.independentpowerlifting.com/http://remingtonsgym.com/The GHR is an essential tool for the development of speed and power for both dynamic field athletes or strength athletes by strengthening the posterior chain. The posterior chain plays a vital role in a persons ability to squat or dead lift heavy, or the ability of any field athlete to run, jump, stop and start. The GHR can also be used as an Ab machine or Reverse Hyper. Our GHR has the added feature of band pegs to strap our Jump Sretch bands to!
