I watched the video again a couple times and checked out his site. The bar he is using is a curved bar, it’s not a straight bar, and doesn’t flex or bend at all, which I would expect to see at such high weight. He doesn’t appear to strain nearly as much as other power lifters do at such high weight. Also there are 8 plates per side, which is 765, not 1000. I’m not at all trying to be dick or argumentative, I’m just skeptical of what I saw.
