157 is about right. Everyone seems to equate "big" with healthy. Not necessarily. I'm 6'1" + and weigh 162. When I was a semi-competitve cyclist I was 145 and could ride for 12 hours in hilly terrain without a break.
The biggest key to keeping up the exercise it to find an activity that you like to do. That makes it super easy to find time for it. Karl obviously loves to be on his bike. That trip across the bridge for lunch, I bet, is a joy for him.
Congratulations again Karl on the new lifestyle.
I hate to admit it, but Nike's old slogan "Just do it." is the best advice going.
