I think that you are right Barb, especially given that I know that I can go the distance and do manage every time that I go out. I guess mind over matter....if I don't mind the first mile and a half, it don't matter! ; ) Either that or stick with the "Just Do It!" Both work I suppose....long as the workout is happening. I am also with you Barb....once it's finished I always feel a great sense of satisfaction and think....'Now why was that first bit so hard? I got this!'
I'm not a runner or jogger, but have to wonder if it's a psychological thing. The reason I say that is because on days when I don't really feel like exercising, I feel horrible while I'm changing my clothes, getting the dvd set up, etc, but as soon as I get started I have to ask myself what the big deal was and I end up enjoying the workout and am glad I did it. Kind of like cleaning house - it's a horrible job, but once it's started/finished, there's so much satisfaction.
Just a thought. Merry Christmas.
