Get your wife to haul you twenty miles out of town every morning with a pack sack full of rocks to lug home. Running up the stairs in a skyscraper is good too. Carrying the pack sack full of rocks makes it better. Finish your day by running down the stairs. That'll turn your legs to jelly. For upper body, nothing in the world beats a pick and shovel.

When John L. Sullivan was heavyweight champion of the world he went to Nome, Alaska to see what the gold rush was all about. While there he agreed to an exhibition fight with one of the locals, a big Swede that could dig a trench like a backhoe. The Swede beat him up so badly that it was more than a year before he fought again.
