There's no faking it on this machine. The Genesis Hamstring is a genuine muscle builder; plant one foot, slip the other into the heavy-duty cage to start building stability and strength. The burn isn't just in the hamstring - this machine pulls in glute muscles through the superior, consistent resistance of Freemotion cable. Twist the leg to hit inner and outer thigh muscles, with a bonus burn in the core. This machine fits everyone, with zero adjustment.
