Yes, that anxiety is normal but please, please, don't let it stop you from going to fitness classes!
I started trying classes when I was 300+ pounds - and yes, I was invariably the heaviest person in the room, no matter what class it was - and sometimes I still am. I pushed past that anxiety, knowing that by not going, I was only hurting myself. Going to classes is a way of finding exercises that you enjoy, avoiding boredom by mixing up your routine, getting an extra push in your workout from being led by the instructor, and yes, even meeting new people! I have tried all kinds of classes - some I liked and still attend, some I didn't like and never went back - and continue to try new ones. Just this past weekend I braved my fear of being too inflexible and went to my first ever yoga class. And I loved it!
So please, please, do yourself a favor and let go of those fears. Exercise doesn't need to be drudgery, you can actually have fun and enjoy yourself while you do it!
Good luck - you can do it!
