To join or not to join

The question of joining a gym has followed me around for years it seems. Why can't I commit? Am I afraid I'll throw money away? I know that if I sign up, I'll use it -- I have to. Even though I don't like the elements outside, I still get out and run anyway. But in the winter, my efforts to stay in shape always seem so worthless. I hope, very soon, that I will put my mind at rest a join a gym ... or not. Those details are coming soon ...
