Personal Trainer

Agreeing with everyone here also!
If you're uncomfortable in the first visit you wont be comfortable for the next one and eventually you wont want to go.
Three sessions a week is a bit much too - if you do one or two it will keep you on track and you can just repeat what one of the training sessions on your day off.

Use this site as motivation or find a group of frineds on facebook to annoy you into going to the gym.

Agreeing with the meal plan thing too - you need to get the option to peek at it before signing - what if it all tastes gross! You're not going to stick with something awful! Also what insaine person designs a meal plan without allowing a slice of cake on your birthday or pudding on Christmas!

Run away.. use the motivation of getting as far away as possible to spur you on with running!
