Polar has a program for this. Orange theory and a few others. Game changer for Wodify. Being able to see current athlete heartrates live on coachboard would give the coach ability to assist certain athletes.

Tracking Calories burnt off during workout. I know that is not easy but would be very useful to use the information in other fitness apps. Thanks!
