I enjoyed this article and took away from it some ideas that are helpful to me:
Exercise at any size because movement feels good.
Don't worry about how it looks or what other people think.
Do the exercise you like to feel good and have fun.
If competition with exercise makes you feel worse or stressed out, take it out, exercise doesn't have to be competitive.
