The Discovery of
DYNAMIC-TENSION

"Well, sir, I was standing there in front of a lion's cage, and the old gentleman was lying down asleep, and all of a sudden he gets up and gives a stretch.  Well, he stretched himself all over - you know how they do, first one leg and then another - and the muscles ran around like rabbits under a rug.  I says to myself, 'Does this old gentleman have any barbells, any exercisers?  No, sir.  Then what's he been doing?'  And it came to me.  I said to myself, 'He's been pitting one muscle against another!'

"In less than twelve months by this method of exercising, I doubled my weight, and I became so strong that I beat up the guy who had given me the beating."
