This thread has been a joy. I have "thunder thighs" from my 13 mile commute. But then I am a natural Mesomorph, my genes give me the heavy quads as surely as the biking. Next time we can factor that in. When I realized the long term problems I might have with body-building I went back to my original love - Cycling. My main interest has been in ultra rides. For that I would train my stomach, back and neck muscles, for which I do not need a gym. If I lived closer to the San Jose Velodrome I would be back pumping iron. As it is dropping that last 18 pounds is the best thing for me.
