The block seems taller than he is, and he is a tall figure. It's about two times taller than it's width. Estimating 1.2m wide, 2.4m tall = 3.4 cubic meters. One cubic meter of limestone weighs 2.7 tons. That would be 9.3 tons in total. He lifts it on his shoulder like it was Atlas stone of merely 0.15 tons. By this feat, he can lift 62 times more than the strongest man, and he isn't even sweating in thick clothes. To compare, the lovely Panzerkampfwagen II weighs "only" 9 tons.
