You may have already heard of slapping contests. This strange discipline involves putting two opponents face to face and letting them take turns hitting each other as hard as they can until one person gets knocked out or surrenders. These competitions are very popular in Russia.As expected, the Siberian Power Show just had to take up this colourful discipline. This gym dedicated to weight training and sport, and to testosterone in general, hosted an epic competition, which we’re not likely to forget.In 2019, Vasily Pelmen became the greatest slapper in the world after winning gold at the Male Slapping Championship. He not only won the right to boast at the gym, he also took home 30,000 Russian Ruble, or about £300. Not bad, right?If you were thinking of entering in the competition, think again. This sport isn't for the faint of hearts. This is nothing like the days you and your brother used to slap each other for fun. This is a little more serious.
