The VersaClimber SM Sport Model, available here with adjustable resistance, acts like two cardio machines in one: a lower body stepper and upper body climber. This design creates a unique arm and leg pushing/pulling action that keeps the arms above the heart and over your head: optimal for good circulation and long-lasting cardio results. The SM model is also available with (optional) bluetooth compatibility and voice feedback, so it’s like having your own personal trainer guiding you along.
