Meet the Ropeflex APEX RX4400: an innovative fitness machine that combines rope pulling with the conditioning benefits of an incline treadmill to kick your butt. It has a modular design to serve both as an incline treadmill or rope climbing machine independently.
APEX is as safe as walking but pushes your body a whole lot harder. It has resistance from 40lbs to 250lbs. It has a commercial grade construction.
