Using a Muscle Oxygen Monitor brings many benefits, whether you’re a pro athlete or just starting your fitness journey. The best part is that it gives you real-time feedback, so you can train smarter, not harder. When you overtrain, your body gets tired and can’t recover. Muscle oxygen levels show when your body is getting tired. You can stop early and save yourself from injury. After hard workouts, the monitor can show how fast your muscle oxygen levels return to normal. This tells you how well your body is recovering.
