To get instruction from Coach Berger, take a video on your phone of your typical approach, release and result.  Take one video from behind.  Then move to about 45 degrees of the bowling arm side.  Then move to 90 degrees from you bowling arm side.  You will only be allowed to submit one file, so make sure you do all of that in one video.
 
Give Coach Berger a few days to analyze you video, then go to the members tab on the Bowling Over 50 Youtube page.  Coach Berger will post his instruction video on your bowling game on the members only page.  You will first have to become a member of the highest level.  As long as you are a member, you can continue to submit videos for analyzation, but you can stop at any time.
