My husband is an avid biker…or at least he would like to be an avid biker. He, like me, has let the pounds creep up on him. Anyway, he has a road bike and a mountain bike that are taking up space in the garage. We live in the hills on the outskirts of Las Vegas and the thought of either of us getting on a bike in these hills elicits fear of exploding cardiac tissue and overall mayhem.
