Hooverball is a medicine ball game invented by President Herbert Hoover’s personal physician to help keep then-President Hoover fit. In general, the game is played on a volleyball-type court of grass or sand and involves throwing a heavily weighted medicine ball over the net. Officially, in Hooverball, the medicine ball weighs about 6 lb (2.7 kg) and is thrown over an 8 ft (2.4 m) volleyball-type net. The game is scored like tennis. The ball is caught and then thrown back. The weight of the medicine ball can make the sport to be quite physically demanding.
