The first thing you need to know about this machine is that it isn’t really a glute/ham developer. It is a glute/ham/back developer.
The second thing you need to know about this machine is that it was designed by the inventor of the glute/ham/developer, Dr. Michael Yessis. To paraphrase an old action movie, he has forgotten more about physical conditioning that you and I will ever know. So, when the good doctor came to us with a design that is intended to be the most complete posterior chain developer on the market, we paid attention. And then we built it.
In creating the Yessis Glute/Ham/Back Machine, world-renowned biomechanist/kinesiologist and sport-specific training expert Dr. Michael Yessis applied several decades’ worth of expertise and insight. Features that separate this device from all others include:
According to Dr. Yessis, most athletes under train their posterior chain and core muscles and don’t even know what a GHD is. For those that do, many don’t know how to properly execute the exercise. The instructional DVD and manual that is supplied with the 7006 makes certain that athletes walk away from this machine not only sore, but with a fresh understanding of what it takes to increase running speed, acceleration and jumping ability – along with a much healthier lower back and a stronger core.
