Walking is the #1 fitness activity in the world. TreadClimber by Star Trac builds on this everyday motion and makes it exponentially more effective. With its unique design, the front foot steps up as much as an 18 incline, but the treadle falls, so at push-off, users are stepping on flat ground - it's essentially like walking on sand. The TreadClimber also allows for a natural stride length, so there's no compromise for short or tall users. It brings a new challenge to walking without any comfort drawbacks - and not to mention, it brings proven results. We're talking a high-burn, low-impact workout that burns 2x the calories as walking the same speed on a flat treadmill. Patented design and movement pattern maximize caloric burn and motivate users to work harder, burning up to 2 times more calories than walking on a flat treadmill at the same speed User defined dual ramping decks provide an incline to flat step pattern, capturing all the benefits of a treadmill, elliptical and stepper
