I used to think bodybuilding was an odd thing to do but not anymore. Look at Lilli Ewing - champion bodybuilder. If all young people (and older people for that matter) followed her example, this country would not have an obesity problem. It would also not have so many health issues. We would feel spectacularly well. It's not necessary to develop your body to the extent Lilli Ewing has - she does it because she is a professional trainer and a competitor (Like Arnold, the Governor of California) - but we can all benefit greatly by taking exercise more seriously. And the discipline that working out develops will help us tremendously as well. See for yourself - http://bodyspace.bodybuilding.com/LilliMarlene/
