I remember the last time I was around 55 kg which was after one of my comps and I struggled with my fitness. I remember how hard body weight exercises felt and I could barely run without almost keeling over. I am much fitter now and I know my 55 kg has more muscle than previously.
The other thing I noticed on the weekend was that my friends were complaining how they were cold and I was walking around in jeans and a singlet. I'm usually a bit of a frog and have been known to wear a jacket when I go out in summer but I seem to be running a little bit warmer than normal. I was wondering if my metabolism has increased and I'm therefore generating a bit more heat than I used to.
There are times when I think I would like to see what my body composition is just to see how much muscle, if any, I've gained but then I think, meh, why bother.
