One of the best things about these monitors is that they give real-time data. That means you can see the changes in your body while you're working out, not after. This is a big help because you don’t have to guess anymore—you can just look at your data and adjust your workout on the spot. This data is usually shown on a smartphone app or a connected watch. You’ll see percentages like “SmO2 65%” or “Total Hemoglobin: 14 g/dL.” These numbers tell you how much oxygen is in your muscles and how much blood is flowing there. Many apps show it in graphs and color zones so it’s easy to understand even if you’re a beginner.
