I practice WTF TaeKwon-Do and would like to keep track of heart rate during training sessions.
I have seen the advice about the effectiveness of fitness trackers, and I'm convinced about the effectiveness of heart rate monitoring. So my question is more specific about how practical or safe is to wear such trackers.
Wrist mounted HR devices don't seem appropriate, and probably won't be allowed by my instructor.
A chest mounted device, seems seems a good option: while in practice it's not expected to be hit on your plexus, and when sparring with contact we use chest protection vests.
To avoid the problem of having the chest strap move out of place, I found a t-shirt with included sensors and a mount for the sensor device, designed for running.
Is there any advice against using a chest based heart rate monitor?
