having to fit in time to shower is a huge excuse for me! I have really long thick hair that takes me an hour to dry & style. The last thing I want to do is get it all sweaty and stuck to me so I have to wash it again. you've given me a way out of my excuse (thank u?)!

Also it is true to say that "It's not clear that exercise has much impact on weight loss". Excercise gives you muscles and muscles are heavy. anyway you can be fit and still be 'fat'. even if your not losing any weight you are definatly still improving on your overall health. Thats what the focus should be on. If you doubt me on this, go check out the real reason the BMI scale was invented - Nothing to do with what it is used for today. astrology not biology.
