I'm 35 years old. I have a three year old daughter. I have just been told by my doc (in a very nice way) that I could stand to lose 20 lbs. OK, 20 - 30 lbs. I'm under the 200lb mark, but I'm also short (5'3). I never really thought of myself as an Athena cyclist. I have always just biked as alternate transportation.
Any tips on how to transition to biking for fitness/weight loss?
