i am on day 2 of my free week at curves. does anyone else here go to curves? i haven't exercised in MANY years, and i forced myself to go today...glad i did. felt pretty good when i was done. i'm just wondering if the 1/2 hour of circuits really helps tone and build muscle? also wondering if it will begin to feel too easy too quickly. debating on whether i should get a membership or not. i know i want to join a club, and i like that it's just for women. i also like how everything is laid out and there's no guess work. what are your experiences with curves? thanks for any input.
