When I was old enough to think about trying out for a middle school team she decided to teach me her tips for success . She said I should do a little bounce at the end of every stride . Just pop up , effectively translating a good deal of my forward motion into useless vertical motion . I was young and still assumed my mom was right about everything so I completely changed how I ran . I ' m 23 and still haven ' t unlearned it and now get shin splints anytime I decide to run for exercise . Thanks Mom .
