You are correct on the Weights per side, however you left out adding the Olympic bar and Collars which are 45lb.s total equaling 625 lb.s . The video is ligit . Taysom has seriously strong legs.
Yeah, I did forget 45 for the bar, lol. Those are not comp collars though. Comp collars would add 11 more lbs. 12- 45’s, plus 45 lb. bar, plus 4- 10’s would be 625.
