“The Great Spadoni,” aka Paul Krause from Germany, was one of the great masters of lifting, balancing and juggling heavy weights, a discipline known as jongleurs de force.
One of his best known feats is pictured at the right:
To begin, he was driven upon the stage in a full-sized dog cart. He then dismounted, removed the wheels — which were then set spinning on pivots fixed to the points of the shafts — lifted the dog cart in his arms and finally balanced the whole affair on his chin.
The balance aspect alone is certainly impressive (to say the least!), but the amount of whole-body strength involved in getting the cart into position in the first place and the level of neck strength necessary to keep it aloft, may be even more so.
