I’ve been using Strava to record weight training, workout, yoga, etc., using a Polar HRM. My weight is set in my profile. I do see the HR during the activity. The activity record shows a average and max HR, as well as a HR profile vs time, but no calories. I’ve used the Polar HRM through the summer on bike rides with no issues (calories shown - but getting data from Wahoo Element).

I did search community for other posts regarding this. Saw similar question from 5 or 6 months ago that said bug was fixed. I do have the latest version of the app on my iPhone as far as I can tell. Thanks!
