I just got a whoop 5 and also have a Garmin watch and bike head unit. When I swim or bike or lift, the whoop calories are much higher than Garmin. If it matters, I do wear a hr strap on the bike but not in the pool or when lifting.

I know neither is going to be 100% accurate but I am finding whoop 20-30% higher than Garmin. I would have thought the difference would be closer.

How accurate is the Whoop 5?
