Featuring a 10-level adjustable damper control, this air-resistance system allows you to customize the intensity to match your fitness level. The internal drive mechanism enables alternating arm movements, simulating a double pull skiing technique for a dynamic and effective workout. Built for durability, it includes ergonomic handles, a sturdy steel frame, and lightweight, high-strength drive cords for smooth and efficient performance. The LCD screen tracks your distance, speed, pace, calories, and wattage, helping you monitor progress and stay motivated. Important Notice: Ensure the unit is securely mounted to solid material, such as wall studs. For other wall types (metal, concrete, etc.), consult a building professional to prevent improper installation and potential injury.
