Turn short sessions into real results. The Sunny Health & 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. | Sunny Health & Fitness | | Smart Foldable Cardio Stair Climber with SunnyFit App Trainer‑Led Workouts and Performance | Gray | Best Buy
