Umberto Pelizzari is an Italian freediver, widely considered among the best of all time. He’s the only one to have established world records in all freediving disciplines that existed at that time – Constant Weight, Variable Weight, and No Limits.
He became famous for his rivalry with another top freediver, Pipin Ferreras, originally a close training friend. In No-Limits, Pelizzari and Ferreras pushed each other deeper and deeper and became the focus of the 2001 IMAX production Ocean Men.
During his career, he achieved depths of 82m in Constant Weight, 131m in Variable, and 150m in No Limits. His best performance in static is 8’, and 19’56” (during medical tests) after breathing pure oxygen.
He’s also done work teaching, has worked on television shows, created the Apnea Academy, and authored the widely used Manual of Freediving.
More people have walked on the moon than have been to some of the places Jill Heinerth has explored right here on Earth.
