Bah, nasty exercise. I know the feeling. I've been doing it so long, though, I've finally got it down to an art. However, I have a gym that has like *$#@*#$* Everything under the sun, so it makes it much easier. Not to mention the best hot cocoa ever afterwards. And a hot tub. Mmmm, hot tub.
My weakness was the food. I have to be a complete nazi about what I eat - Not calorie counting or anything, but like, 'HALF MA PLATE MUST BE VEGGIETABLES, LOTS OF FRUIT, ONE FOURTH MEAT, iiiiitty bitty bit of carbs.' because I spent the last seven years on and off bedrest which like, slaughtered my metabolism.
*holds up sign with an animated bed wandering around on a dark London night, killing digestive track prostitues left and right.* Very Jack the Ripper and all that.
