Hi Dawn, Sandra is right don't get hung up on how you look, I was certainly doing the classes at my heaviest (almost 19 stone). Even now at just under 16 stone I probably am the biggest there but I still get more of the moves right than some of the fitter people! Just go and have fun, its hard to forget how you feel about yourslef but if you throw yourself into the class you will soon just be singing along and shouting with everyone else! I know that attending these classes now will not only help my weight loss, its a great way to tone up, socialize and generally feel much better about myself. Let us know if you decide to go along!
