I'm running and doing classes like spin, conditioning as well as boxing when
I can fit it in. I'm feeling a little bit fitter all the time but I seriously need to get my bmi down. I want to join the territorial army after being out of the regular army for ten years. Am I doing the right thing by doing all different classes (going to try sambo on Friday) or is there a conflict between any exercise that will build muscle and lowering my bmi?

I know a lot of people think bmi is rubbish and we should be judged on fitness, but it looks like this is just something I'm going to have to do. I hope to get what I want I won't have to just run, starve and run.

Thanks.
