The Sunny Health & Fitness Manual Treadmill is a non-motorized treadmill with two belt-driven flywheels that spin only when you walk or run. A fixed 14% incline adds resistance, and the foldable frame lets it tuck into a closet or corner. It suits walkers and joggers who want an indoor cardio option without power cords or motor maintenance, and it costs far less than a motorized treadmill. The trade-offs are real: no motor means no preset speeds, and the fixed incline is steep for easy flat walking.
