A **mini stepper** is a small, portable exercise machine that mimics stair climbing to offer a low-impact cardiovascular workout. It typically features two foot pedals that move up and down, allowing users to step in place. Some models come with resistance bands for upper body exercises. Mini steppers are popular for home gyms because they are space-efficient, easy to store, and provide an effective way to strengthen leg muscles, burn calories, and improve overall fitness in a compact design.
