I'm trying to follow the tips in the 12week weight loss plan to increase activity. It says to try and encorporate activity into every day activities. Such as brisk walking, taking the stairs etc. The thing is, I get really hot when I do these things. I think you're supposed to get hot if you are being active enough. But then it seems really impractical to be sweaty during the day. I don't like arriving at work sweaty or being sweaty when I'm out shopping or whatever. It doesn't seem hygienic to do any exercise at all without being able to immediately shower and change your undergarments and clothes. Am I being too fussy or is thee a way around it? How does everyone else manage/feel about increasing activity throughout the day?
