the LA the last thing that I would want you to do Andrew is to copy Usain Bolt sprinting stride because Usain Bolt is 6'5 215 pounds he's a little bit more Dynamic than you he's probably got slightly longer Achilles tendons than you he's probably got tight smaller joints than you he's probably a lot more elastic than you are he's probably a little bit more coordinated than you are so why would I want you to try to copy that
