Russians brutally slap one another during a show of strength in Moscow.
The bizarre and painful competition took place as part of the Sarychev Power Expo held in the Russian capital, April 29.
Contestants appear increasingly apprehensive as their faces bruise and redden, and their features swell.
Crowds surrounding the spectacle wince, moan and clap as they exchange blows.
Sarychev Power Expo aims to promote power sports, patriotism and the strongest men in Russia.
