Medicine Balls

Medicine balls are the classic strength and conditioning tools of boxers, but have been adopted by a variety of martial artists and other athletes. Traditionally made of leather shell with a heavy "soft" padding on the inside, today you will also find synthetic fabric shells, as well as various "hard" rubber designs. For the classic medicine ball exercises, nothing beats the feel of a well conditioned and worn leather med ball.

"In bare knuckle fighting, the number of rounds was never consequential. The time length of the fight was the important thing because under London Prize Ring Rules, a round ended when a man was knocked, fell or was thrown to the ground. Some rounds lasted many minutes, others only a second or two."
