Eek at the condemnation of Madonna's arms! That's how I get when I start to exercise proper! When I was a more athletic youth, I had body fat measured and the reading it came up with was that I was underweight. Which was funny, because I weighed 9.5 stone at 5ft 4 at the time . When I do exercise, I metabolise fat well and create muscle easy. I certainly was NOT aneroxic. You dont see many sprinters or pentathletes who are....
The problem I have nowadays is getting the motivation to exercise in the first place.......
