Riding my bike up Left Hand Canyon this fall, a friend asked me about the connection between osteoporosis (frail bones) and cycling. Her question encouraged me to do a little research.

I thought I was safe from osteoporosis because I'm active. I bike and hike, run and do Pilates. But still I may be at risk for osteoporosis. The facts are sobering, and not just for women! Fit middle aged men who cycle 12 hours per week are at increased risk for developing osteoporosis. Bone loss when studied in such a group was about 10% greater than for a similar group of moderately active non-cyclists. One study even showed that cyclists have lower bone
density than couch potatoes. WOW...
