That guy is a clown and he has no credibility with me. He's uses the classic method of operation of taking credit for the athletes he "trains." Another guru who gains some fame then a few athletes thinks he has secret knowledge and flocks to him.
What really sealed the deal is the numerous times I catch him putting out garbage. He actually wrote it's technically an error for an Olympic lifter to rise up on their toes when pulling a weight in the snatch and clean. He obviously had no experience. An Olympic lifter explodes with speed upward and rise upward almost like a jump. To say he should be flat footed shows his lack of experience but not the lack of knowing when to keep his mouth shut.
