Rogue Fitness, and independent fitness equipment sales company, recently produced this interesting documentary about traditional Basque sports (also known as rural sports) based on feats of strength and rooted in rural labor such as farm chores and quarrying. These sports include stone lifting, wood chopping, anvil lifting, tug-of-war, weight carrying, and stone dragging.
As well as explaining what Basque traditional sports are, through the direct testimonies of their most famous exponents, the film also reveals much about Basque culture in general and includes some beautiful cinematography of the Basque Country. Most of the focus of the film is given over to the harrijasotzaileak or stone lifters, with detailed explanations of how the stones themselves are cut, how the stone lifters approach their task, and so on.
