I got on my bike and started training in march (plus gym work) same time as I went on a diet. I have lost 1 1/12 stone but the clothes I am into now tell me I should be almost 1/2 a stone lighter and I am convinced it is the muscle/fat weight thing. I have never been so fit nor continuously done so much exercise and it feels good
Did I read right the idea that in rigourous excersise the weight gain of muscle can be around 4 kgs? if 1 kg=2.2lbs that 8.8 lbs, over 1/2 stone and that would match my theory of my own wieght loss.
A friend of mine is a runner and didn't get to do any training for quite a while, she then found she was lighter on the scales than she had been in ages, yet size wise she was a lot bigger.
Anyway, I would agree ithe weight is probably more quads, and possibly gluts than the calves.
