Abstract: A contralateral hip and hamstring training device which mimics the body position and biomechanics of walking/running is provided. When using the training device, a user is positioned in a partially supported lunge with the front hip flexed just above 90 degrees and the back hip extended to at least neutral at the hip by use of an incline bench or seat pad with no seat back. This position allows users to engage the hip flexors of their back leg while the hamstring exercise is performed on the front leg creating true pelvic stabilization using the same counterforce mechanics required during walking/running. Because the user is able to adjust the amount of hip extension and muscle activation on the back leg in real time, the training device provides for adequate leverage for training the hamstrings in both Hip Extension and Knee Flexion simultaneously and through a full range of resistance levels.
