I also use that grip and never had a problem...He was very shaky...and way to slow on the way down...its always that 1 rep max were someone gets hurt....
Doesn't look like he had a pull either...also he turned his left wrist forward that why he lost his grip...he was trying to lock out beyond the center of his shoulder....Big Mistake....
he also didnt have on a new bench shirt...it looked an old inzer suit could be wrong on that 1..
The spotters dont look like they trained with him either..they look like kids that walked off the street....
Ive never competed with someone that didn't have a clue spotting me either...you are allowed to have your own guys there....
