I always had walls around "exercise." It took me back to those humiliating days in grade school when I was the clumsy kid, last chosen.
I didn't have issues on the playground though. I could play on the bars, chase boys and play hide and seek.
If I get out there and just play, be it dance, act, chase the dog, ride a bike or swing on the swings, I CAN move my body and burn calories. It's just a paradigm shift. In my mind exercise is bad, but play is fun, So I choose to laugh and play.
