Taking the plunge...

I felt the same way but everyone is so different that we always end up with a good mix of people in the group classes. In zumba class, there's skinny people who can't dance and bigger people who can. There's also some bigger people who are more fit and can do the whole routine and some skinny people who can't. Same in the pump classes. I'm super weak so I workout with just the bar sometimes and I'm not embarassed. What would really be embarassing is if I would let that keep me from the classes and from bettering myself. I love the classes now and have made so many friends in the few months I've been going. Also, think of it like this. If you were a skinny minny super athlete or something and saw a newbie walk in, I'm sure you wouldn't judge. You'd think, good for her!
