Is my HRM working right?
I just recently bought a Sportsline Duo 660 HRM that comes with a chest strap. I finally got it set right with my body measurements, etc. But when I did my 30 minute P90X3 workout today(CVX). After the cool-down the clock was at 35min 32sec it read 920 calories. I was like, eh.. Okay I'm a big guy I can see that. Well then…
