Geez, I didn't know it was an either-or kind of thing. I've been struggling with getting exercise here in Houston because I do run outside, and it's just downright unbearable right now! If I had the discipline to run on a treadmill for a given period of time, I would probably be better off and more consistently exercising right now. As it is I run best when I'm chasing a spinning piece of plastic.

Regarding some topics mentioned above: I'm naturally thin and physically active, but I struggle a lot with flexibility. Lucky for me, few people look askance at you for not being able to sit cross-legged. I have great respect for those who struggle with their appearance and face societal judgement for it. I am lucky that my shortcomings aren't considered fair game for public disdain.
