The CLM sensor allows me to train in a very targeted way. As a long-distance triathlete, it is very important for me to stay in the right training zones. With the sensor, every training session is a hit because I can achieve exactly the target for that training session.

I also find using the sensor practically very easy, exactly the same as heart rate monitors as we already know them, the CLM sensor uses a chest strap and you can quickly see the data collected in the app.

Heart rate, fluid loss and real-time lactate are all measured so I can see immediately after training how much fluid I have lost (and thus need to drink extra if necessary).

During training, for example, I can perfectly stay just below my tipping point by keeping an eye on my lactate level, allowing me to train this tipping point and move up with it.
