Designed to mimic walking up a staircase, one reviewer calls it their “stairway to fitness heaven,” noting that it’s a surprisingly intense workout: “After just a few minutes, my legs were burning like I had climbed Mount Everest. But the best part? I didn’t even have to leave my house or put on real pants. Take that, gym membership!”

With an adjustable stride from 5 to 15 inches, the stepper targets different body parts — from your calves, thighs and hips to even your tush and stomach.

While walking pads have boomed in popularity, this small stair stepper helps you move, but also goes a little further. The machine has an LCD screen that displays calories burned, step count, time elapsed and more. Yet, unlike other home fitness equipment, this gadget can easily stow away out of sight, whether in a closet or under a desk. And at 16 pounds, you can take it just about anywhere.

The stair stepper is also only 16 inches tall at its maximum height and comes with two resistance bands that latch onto its base for additional full-body conditioning. It can hold up to 300 pounds, with adjustable foot pedals that can hold up to a men’s shoe size 12. The brand also describes it as a particularly quiet machine, so it won’t disrupt others around you while you step.
