The "Train.Red Main Sensor" Data Field allows the Fyer sensor to display SmO2 inside of native Garmin Activities and to be recorded to the device's .fit file and uploaded to Garmin Connect.

The official Garmin app for the Train.Red muscle oxygen sensors, the new metric for performance. To move, your muscles need energy. The most efficient way to get this energy requires oxygen. We measure the oxygen saturation in your muscle to help you improve.

What does Train.Red do for me:
Whether you’re an athlete, coach, scientist, physio, or anyone involved in sport, Train.Red has something to offer you. Simply because your muscles play a key role in human movement.  We track your muscle oxygenation, more specifically, the hemoglobin concentration changes. 
The Train.Red sensors measure:
-	SmO2, Muscle Oxygen Saturation (%)
-	O2Hb, Oxyhemoglobin (mM)
-	Hhb, Deoxyhemoglobin (mM)
-	Thb, Total hemoglobin (mM)
-	HbDiff, the Hemoglobin Difference (mM)
The "Train.Red Main Sensor" Data Field allows the Fyer sensor to display SmO2 inside of native Garmin Activities and to be recorded to the device's .fit file and uploaded to Garmin Connect. Want full functionality? Download our Train.Red official app on your smartphone.

Our app displays the oxygen saturation in your muscle live and use the other metrics to provide you with actionable insights in real-time. Our AI and advanced analysis options translate this data into 5 different muscle states showing you if your muscle is recovering, or approaching its limits. If this data sounds like coming home, perfect. We allow exporting your data to .csv or .fit files for an in-depth analysis of all your data.  Every single training session is stored and can be analyzed or exported afterward. 

How do I use Train.Red?
The Train.Red sensor is a light-based wearable that you wear directly on your skin. You’re free to place the sensor anywhere on your body, but know that this is a hyperlocal metric that will only tell you something about the exact location you place the sensor.  We recommend wearing the sensor on a primary involved locomotor muscle, a place on your body that is active during the activity you’re performing. e.g. on your thigh during cycling, or squats, the middle part of your upper leg during running, or on your lower arm during climbing.
