I was recently reading about how one barrier to physical activity may be that people do not consider their own environment safe enough to allow them to walk, cycle or take other forms of outdoor exercise.
I found this bit of information especially timely because I had wanted to run outside last night, but I dragged my feet doing other things, and it got dark, so nixed the jog and popped in a workout DVD. I do feel safe in my neighborhood, but I don't typically like running while it's dark anywhere. Let me clarify that I don't think running at night is a bad idea for everyone because some people run only at night, but for me, I feel safer running when it's light out.
All this got me to thinking about you guys—have you ever skipped exercise because you don't feel safe?
