Exercise Anywhere Anytime: The leg exerciser suits office workers, the elderly, and rehab users. Use it under your desk, on a home chair, or by the sofa while watching TV. Its low-impact workout is gentle on joints. It relaxes leg muscles, boosts blood circulation, burns calories, improves heart health, strengthens muscles, and aids leg recovery. It's a convenient way to stay active throughout the day. 3 Workout Modes: This leg exerciser offers 3 modes. In non-electric mode, pedal manually without a power cable. Auto mode provides 15 preset programs (P1-P15), running for 30 minutes with automatic speed and direction selection. Switch programs with the Auto button. In HR (manual) mode, set your own direction (forward or reverse), workout time from 130 minutes, and speed levels from 115 via the machines panel or remote control.
