in upper body daya I can leave the gym basically dry. leg day though I’m drenched
both days I push to or close to failure
roughly same amount of time
is it just because legs haveuch more muscle mass?
I’m not an expert, but I’d say it’s because your legs are basically half your body. Not only that but most leg exercises require the use of other muscles. Like, if you’re squatting with weights you are using pretty much every major muscle group in your body.
I’ll add to this that legs and feet make for surprisingly good heat dumps when blood is pumping, so if you’re using them to generate the heat, the rest of the body has to do the radiating instead.
Leg’s are half your body (more or less). On top of that some exercises involve your back and core muscles, like squats. So you’re actually engaging a good chunk of muscles when working out legs.
