those weights seem VERY light, was he doing it in circuit form?
i saw a vid of him doing something like 450lb squat for 20 reps
it was 405 for 20 he did in that set you saw and he was doing a drop set on the night he passed away, something like 505x8, 405x8, 315x8, 225x8 and 155x8 then immediately flipped a tire and loaded a heavy stone.
