This complements the Hip & Knee Solution in an outstanding way. We recognized the importance of joint-specific, controlled exercise for the hip. A leg press was not enough, and hip abduction does not target the largest human muscle, Gluteus maximus. But training the glutes in a safe way is very challenging. They are connected to the pelvis, and training with large forces can cause an uncontrollable tilt that endangers the lower back. We are very pleased with the results of this device. It is certainly one of the more remarkable devices in our lineup.
