On Sunday night, I decided it was time I began training my body for when the temperatures drop and I can start riding again. Mountain biking, road biking, whatever, I gotta get out and ride. So I put on some angry, aggressive music and cranked out three sets apiece of push-ups and sit-ups. I could hardly move for four days. How the hell am I supposed to survive an hour on a bike if I can’t even do some sit-ups? Things are not looking good.
