Hang in there jetskiguy, and don't let them intimidate you! I used to feel the same way when I first started out. Now those muscleheads are used to seeing me in there and I've even gotten a few comments recently telling me how strong I am for a girl, LOL!

Now I think I get most of the stares when I'm in the cardio room as I do a hard 30 minutes on the elliptical and then go over to the treadmill and run another 3 miles at a decent clip! I'm usually drenched in sweat - much more than anyone else in there!
