Walking is the #1 fitness activity in the world. The dynamic TreadClimber5 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 degree incline, but the treadle falls, so at push-off, users are stepping on flat ground, similar to walking on sand. The TreadClimber5 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. Usage rates for cheap fitness equipment is laughable at best. Gimmicky stationary bikes and light-weight ellipticals seen on infomercial and leading sporting good stores, do nothing more than waste your time and money. People that are serious about their fitness are willing to invest the amount necessary to buy equipment tha
