moonstruck sorry, though it looks cool and shows agility that really does not take much strength.. and regarding Lou, reports of him working with Michael actually stem back years before this is it! In the 90's it was mentioned as well..
Michael was agile, fast, resilient, a lot of stamina (most of his life anyway)... But lets not try to say he was physically strong when it comes to having the power to move heavy weight/muscular strength.. The other athletic attributes take strength and conditioning which he had though!
