I would guess lack of oxygen to the brain from the strenuous lift and then the celebration threw him overboard...and lights out! I've come close to passing out after a hard lift, but luckily never have. I also don't celebrate after lifts, not that their is anything wrong with celebrating.
Same kind of thing that can happen to you if you have heart trouble. Luckily that hasnt happened to me. Good to see he wasnt seriously hurt. Hopefully his heart is healthy.
Don't see any humor or anything funny in that video, damn the guy got hurt after doing to him a very heavy deadlift. There were many times I felt like passing out, seeing those black spots is not funny but you know you pushed yourself to your limits. Just glad the guy was not seriously hurt.
yeah he could have gotten hurt bad but he didnt he got a few stitches in the chin big deal so yeah i think its funny. and he shouldnt have been lifting like that so if ur gonna have terrible form and video tape yourself, expect people to laugh.
