A little background here: Kirk trained and lifted in this meet "raw" , which he defines as "wearing just a belt". Kirk weighed 252 in this footage.
He squats 545, 675 and 745.
His last heavy squat workout was 2 weeks earlier, where he did 815x1. He was jumping 20lbs every other week in the squat.
Between those weeks, he would take 80% of the planned 20 lb jump and just perform a single. He felt like this kept himself "feeling" the weight without taxing him too much. For example, if he did 700x5, and 2 weeks later planned for 720x5, he would just single 575 the week after 700x5.
For the bench press, he goes, 225, 405, 445 and 485. He had a "very inflamed rotator cuff which was a nightmare". He benched 505 a month earlier.
On the deadlift, he does 495, 585, 675. The week before, pulled 785.
