You should quit going to Curves and join a real gym. Somehow, Cutler, Warren, etc are still weak enough to use those machines at the gyms they go to.
The leg extension machine in my gym was built in the 1960's, it's got a stack of plates taller than you in high heels you dumb mother fucker.
The only reason I'm going to allow you to continue posting here is because you've got a great avatar, so be thankful for that!
