These days, gyms are happy to have your membership. We no longer are shunned or looked at strangely in gyms. We all had to get started somewhere. Shows like The Biggest Loser and Extreme Makeover have made it accepting to go for physical fitness and not know how to do some of the activities we signed up for (circuit training, aka bootcamp). Most of the people are willing to help each other and want to see you do good. You have to take a chance and chances are VERY goood you will find others in your class that are new or will be glad to offer help if you need it. I am so glad I did this for me and no one has made me feel inferior or dumb. Good Luck and go for it!
