Greco-Roman wrestling has featured in the Olympics since 1896 and is billed by the IOC as “arguably the oldest competitive sport in the world”.

In this type of wrestling, the competitors use only their arms and upper bodies to attack, and can only hold those same parts of their opponents.

But even with that description in mind, the sport certainly leads to a few somewhat unusual action shots.
