Question about Fitbit Charge 2
How reliable is the heart rate measurement when doing bodybuilding? Since it is not waterproof, is it a problem if you do cardio and sweat a lot?
I also do a lot of sport. No problem... I wouldn't go swimming with it, but it should easily stand up to a shower.
The heart rate measurement seems reliable to me, the Fitbit is waterproof enough that there is no problem with sweating...
