man...i'm only paying $7.50 a week, i suppose thats because i'm a student and as such got a massive discount.
i had the same fears/insecurities when i first started gymming but i quickly fitted in and figured out no one really cares how much you lift. nowdays i fit into the muscular but not bodybuilder category which is where i want to be.
when i was working up north i went to the gyms at camp pretty confident with my body and how mych i lift...anyway i enter and there are these massive guys pumping iron and it was like i went to the gym for the first time as i felt all skinny and weak....but as soon as you start working out you forget about all that and do your workout
