Exercise: Lack of Exercise As A Medical Condition?

According to physiologist Michael Joyner, M.D., “physical inactivity is the root cause of many of the common problems that we have.” These problems include obesity, diabetes, joint damage, and high blood pressure. If lack of exercise (deconditioning) was treated as a medical condition, then perhaps more patients and doctors would see exercise as a treatment that should be considered first for many medical complaints.
