I'm fair complected and in okay shape and I sweat a lot, like dripping sweat. The only time I actually accumulate puddles is when I go to hot yoga, but when I run I sweat through my tshirt and shorts...the whole thing. There are usually only a couple of dry spots. I think I used to sweat the same amount when I weighed 40 lbs more though. I always thought it was genetic, but who knows.
I do sweat. Not a whole lot, but certain areas of my body are much worse than others when I work out. But the no sweating thing, I understand because my mom never ever sweats. She's fair skinned, and a healthy weight. She can get very light headed when outside working in the heat. It's something my grandpa (her dad) has too. But luckily I take after my dad.
it makes sense, your body has to learn to become more efficient at cooling down. I hate 2 sweat too. The more i work out the more I start to sweat. That's just the way it is.
