A Muscle Oxygen Monitor is a small device that helps you understand how much oxygen your muscles are using during exercise. It’s like a fitness tracker but much smarter for athletes, fitness lovers, and even doctors. Whether you're running, lifting weights, or cycling, this tool gives you live feedback on your muscle performance. When you move your body, your muscles need oxygen to work properly. This monitor shows you if your muscles are getting enough oxygen. If not, you may feel tired early. By using this device, you can adjust your workout, train smarter, and avoid injuries.
