A look at the Pasquali Brothers (there were actually three of them: Bibi, Harry, and Willie.). They were born in Italy, where their father and mother were both well known circus performers and the boys began their training as soon as they could walk. They took up the family business and made their debut in Russia in 1905 and eventually traveled all of the globe performing feats of acrobatics, equilibrilism, and hand-balancing.

Something else that should stand out is the quality of their physiques — talk about “functional muscle” — this is fairly typical development for those who regularly practice hand-balancing work.
