Hey Molly - if I could give one piece of advice to anyone it would be honestly don't worry about people looking at you in the gym ... Everyone is just too absorbed in what they're doing that they don't care about anyone else at all. They will have no clue as to when you got on a certain machine, how long you've been on it, what level you're doing it on, how fast you're going etc. I really, really recommend going, especially if it's just the embarrassment that's holding you back.
Today's been quite a good day so far! Have been well behaved on the food front and will *probably* hit the gym again later. And only a couple of days until until I can swim every day of the week in our lovely hotel pool in Turkey ... YEAH!!
