Highlights:

He ran the 100-yard dash in 10.9 seconds, shot-putted 56 feet, triple jumped more than 50 feet, and won the high jump in the Big Eight track and field championships three straight years ... After his basketball career, volleyball became Chamberlain's new passion: being a talented hobby volleyballer during his Lakers days, he became a board member of the newly founded International Volleyball Association in 1974, and then its president one year later. As a testament to his importance, the IVA All-Star game was televised only because Chamberlain also played in it: he rose to the challenge and was named the game's MVP. He played occasional matches for the IVA Seattle Smashers before the league folded in 1979. Chamberlain promoted the sport so effectively that he was named to the Volleyball Hall of Fame: he became one of the few athletes who were enshrined in different sports.

The man was 7'1" and ran a sub-11 100 meters.

There's also this from Arnold:

I would go watch him play when he was on the Lakers and we would work out together at Gold’s Gym. He was the only basketball player in those days I saw working out with weights. He did triceps extensions with 180 pounds, which blew us all away. He was so strong. Our relationship extended into making ‘Conan the Destroyer,’ where we worked out every day on set.
