Barrel lifting goes back a little farther than Dnosaur Training… The Japanese painter Hokusai is best-known as author of the woodblock print series Thirty-six Views of Mount Fuji and his most recognized print The Great Wave of Kanagawa. Among his many drawings was this one, “Sakadaru o sashiageru otoko” showing a man lifting a sake barrel overead with one arm. This drawing was completed sometime around the year 1810 but the one-arm press is certainly still a great exercise.
