What counts as &#x27;a lot&#x27;? Is the cyclist doing any other exercising or just cycling? Did they have proper form? Were they predisposed genetically to poor knees or hips? Did they have proper rest between sessions? Were they ignoring over training warning signs?<p>I&#x27;m asking these questions because I have been seeing more and more comments along the lines of exercising wears the body out and it breaks, so do not exercise. Exercising with proper form and rest should not do this. In fact the body should be getting stronger. One of the big things I see, particularly with runners and cyclists is very little thought to proper form. Running and cycling appear easy so I think people often do not think about form or technique.
