Well sweating is one of those things you really have no control over, so it's not a deficiency. The only thing you can control is how you manage it, such as using towels and wiping down any equipment you used when you're done. (I have no patience for people who sweat all over the benches, etc in the free weight area and then move on without cleaning up. There are unlimited free towels available at my gym, so people have no excuse not to clean up their a$$ sweat.)
