After setting over 60 world records over his career, Grigori Novak did what any great former weightlifter would do: he ran off to the circus to become a genuine performing strongman. Eventually, Novak’s two sons Arkady and Roman also joined the act, you can see them above doing a little kettlebell juggling during their act. Kettlebell juggling is pretty impressive on its own, but seeing several lifters doing it at once in tandem is amazing.
