It could be a medical condition. Sweat glands are some of the last things to form in development. I know several people who never sweat, like Aaron appears to.
It deals more with the shape you are in (how active you've been), and diet. AB is very active and doesn't eat a lot of junk food. I think he is out of shape if that picture is from open practice. He needs to learn to balance cardio and strength training.
I bet nobody wants to guard Scola in practice. He is always looks overly sweaty and probably smells bad.
I think this notion that Brooks doesn't sweat is dumb, and frankly, embarrassing to all of ClutchFan members. Who created this dumb rumor?
Pretty clear that he is really out of shape in that video. He looks soft and heavy. But i am going to cut him a break because everyone needs some time off.
How much you sweat is not a true indication of how great of shape you are in. I hope I am just misunderstanding you.
