Me too. I've been cycling all my life. I am not all that fit overall, but I have gigantic hips and thighs which maintain their tone even when I don't ride. I always, always, always climb stairs two at a time. The muscle tone is such that it feels GOOD to pedal hard, better than not doing anything at all. So that's a goal to reach for. I should say the same to myself for working out my upper body. I am a super weakling above the hips.
