Thanks!
Well, I live in South Carolina, so it isn't really an option to walk from place to place, but I can't say that there aren't parks in proximity to where I live where I can go walk.
I can't say that I am a couch-potato, I don't mind taking the stairs and stuff, but I guess I haven't had any kind of structure in my workouts so I tire of them easily. I've tried the gym thing, but I always lose interest in the atmosphere, so I'd rather do stuff at home. I can actually make it all the way through the Tae Bo tapes (not the advanced, the basic one), of course I'm letting out sighs of pain 3/4 of the way through, but I can do it!
I looked at the exercise.about.com briefly and it looks like there is a wealth of info on there. I'll check it out more while at work tonight, I gotta go to bed! Thanks again.
