Abstract: Embodiments of the present disclosure are directed to a computer system of an exercise machine for maximizing muscle recruitment through capability based concentric and eccentric training.

Abstract: The exercise machine in the present disclosure utilizes novel machine mechanics that accommodate and adjust to the spines shifting axis of rotation. Through the use of a multiple, articulating axes a back exercise machine or device that promotes pure and isolated spinal flexion and extension with no need for mechanical anatomical restraint to succeed has been created. Using these mechanics when users attempt to extend their trunk, the device adjusts to the natural shifting axis of rotation of the spine thereby dis-involving the contribution of the hip extensor muscles. In other works, the exercise back machine of the present disclosure is designed to accommodate the complex biomechanics of the spine and to facilitate targeted strengthening of the spinal erectors and deep intrinsic spinal muscles.

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.
