His beard did most the lifting for him. I know mine has to add atleast 10%.
But idk, with the time period I would say some between a west side barbell type routine and some odd strongman type lifts (tires, yokes, ECT) is probable. it's allot easier to see how some of the more modern lifters do it. I've really been influenced by Dan green, the lilybridges, and Russian training styles.
