A mini stepper is a compact fitness device designed for low-impact cardiovascular workouts, simulating stair climbing. It typically features two independent pedals that move up and down, often with hydraulic resistance for smooth operation. Many models include an LCD monitor to track workout data such as steps, time, calories burned, and repetitions per minute. Some versions also come with detachable resistance bands for an upper body workout, targeting arms, shoulders, back, and chest muscles. The pedals are usually designed with anti-slip features and cushioning to enhance safety and protect joints like the knees and ankles.
