Turn short sessions into real results. The Sunny Health and Fitness Foldable Smart Cardio Step Climber (Sf-S025025GY) uses bodyweight for low-impact cardio that works legs, glutes, and core. An extended 9.8"– 24.8" step range with a 21.5" stride lets you choose your reach while the start point stays fixed no preset resistance means your core handles the stabilizing. Three handlebar positions help you find a steady, ergonomic grip, and the triangular frame folds fast for easy storage. Connect via Bluetooth to the SunnyFit App for guided climbs, scenic routes, and progress tracking. The simple Lcd shows time, steps, step rate, and calories so you can stay focused on the climb.
