A cast-iron weight with a handle attached to the top, resembling a cannonball with a handle, used for dynamic strength and conditioning exercises that combine cardiovascular and strength training.
From Russian 'girya' (гиря), literally meaning 'weight,' but the English term combines 'kettle' (referring to its shape) and 'bell.' Kettlebells originated in 18th century Russia as counterweights for measuring grain, then became training tools for strongmen and military personnel.
Kettlebells were so important to Russian strength culture that in the 1940s, every Russian village was required by law to have kettlebells available for citizens to train with - the Soviets believed kettlebell training created superior soldiers and workers!
