I was on the treadmill doing an interval between running and walking for 35 minutes, then for the other 25 or so I was on the elliptical and bike machines. I was sweating like a mother ****er with my heart rate getting up to 180.
Wasn't sure how realistic my calorie burn might have been. It doesn't really matter in the end though. I eat the same range of calories everyday. It's just fun to have an idea of the calories burned with some degree of accuracy ya know?
I will say I was pretty amazed at how accurate the heart rate monitor was on the the Apple Watch. While I was holding onto the machines I had my heart rate tested and it was the same exact number as my watch. Tried a chest strap monitor as well. Same numbers. For my amateurish bodybuilding, Apple Watch will do just fine. I like being able to just focus on one device/ecosystem that syncs with all my crap vs "ok I'm at the gym. Gotta take off my watch and put on my chest strap and then yadda yadda yadda". Just get in the shower room, wipe off my watch, switch my band and done. Then check apple health and fitness pal for all my info. The convenience just can't be beat.
Still trying to decide if I'm gonna have a go to band for the gym and if so, which it'll be between my nylon and sport. The nylon is soooooo comfy
