Working out at the gym is sometimes not where we "look" our best. And we sometimes can use that extra push to do that one more rep, one more step, one more crunch. I try to give someone that little smile or word of encouragement. "Wow, you really were working hard there!!" or "boy, I wish I could be as smooth as you are"
Or maybe in the locker room..."Great shoes!" Something like that...every time I go. The first time I set foot in a gym at the age of 57, I was scared to death!! Totally a fish out of water. I remember one women who just smiled at me and said "keep going, it will get better."
I say that everyday.
