I joined because my swimming+aqua aerobics for two weeks was the price of membership per month so it makes financial sense.
I swim 3 times a week and do aqua once a week. I am also v.fat and unfit (although through swimming have pretty strong arms haha).
I thought about a step class? But I don't want to embarrass myself!
I know I need to do something cardio but what? I fancy using the bikes in the gym would that help?
