Stair Stepper Machines: 5 Fast Facts

Fact #1. For 70 years between 1929 and 1999, the National Sporting Goods Association Trade Show attracted innovators, inventors, success stories, and scam artists from around the country. They went to meet, network, promote, and profit in the sports market. It was there in 1985 that three engineers from Oklahoma introduced the first stair stepper machine.
Fact #2. The original stair stepper worked more like a treadmill than the stair climbers of today. Instead of rotating a flat belt around two rollers, it rotated an entire set of stairs. The inventors came to the trade show with studies about the benefits of stair climbing, and their product exploded in popularity.
Fact #3. Most stair climbers are either spring-loaded or piston-operated. When you step down on a spring-loaded model, your body weight combines with the pressure you exert downward. This stretches a string coiled beneath the step under either foot. These springs provide a small amount of recoil to get your leg positioned for the following step on that side. Piston-operated machines work much the same way. Your weight and exertion push air out of a metal tube through a small opening. The air pressure creates the resistance and the recoil.
Fact #4. A few of the newer stair climbers on the market incorporate wheels into the traditional design. The resistance in these comes from an internal adjustable belt. It's akin to what you might find in some rowing machines and recumbent bikes. The rolling motion reduces impact and mimics the movement of an elliptical machine.
Fact #5. Some stair stepper machines offer additional workout options to complete the experience. They usually target one or more of the upper body's muscle groups. This is because the stair climber itself already does such a good job working the muscles in your lower half.
