Overview
Sunny Health & Fitness's compact stair stepper, a folding cardio machine with adjustable step depth, tilt adjustable footplates and an LCD that tracks time, steps, step rate and calories.
Unlike a stepper with fixed hydraulic resistance, this model lets your own pace and step depth set the effort, with 9.8 to 24.8 inches of vertical travel per step. It pairs with the SunnyFit app for guided climbs and metrics, though that layer needs a phone or tablet.
- 9.8 to 24.8 inch vertical step travel
- 330 lb frame weight capacity
- Tilt adjustable footplates
- Folds flat when not in use
Who it's for
Fits people wanting a compact, low impact cardio machine for a small apartment or home gym, rated up to 330 lbs. Not for anyone wanting fixed resistance levels or full coaching features without pairing a phone to the app.
Pros and cons

Performance notes
Step height ranges from 9.8 to 24.8 inches with a 21.5 inch stride, and because there's no preset resistance, workout intensity comes from how deep and fast you step rather than a dial. Tilt adjustable footplates shift emphasis toward calves, quads or glutes, and four handlebar positions accommodate different heights.
