Health information
The book and this site share general information about bike setup, stretching, strength and balance. They are not medical advice and do not diagnose or treat any condition. Results differ from person to person, and nothing here is a promise that you will be free of pain. Check with your doctor before you start any new exercise, especially if you have a heart condition, high blood pressure, a joint replacement, osteoporosis, diabetes or an injury. Stop if you feel sharp pain, dizziness or numbness that doesn't go away. Bike work involves tools and moving parts, so tighten parts to the numbers printed on them and ask a bike shop if you are unsure.
