Top 100 contestants in Korea like pro mma fighters, olympic medalist, fitness influencers, bodybuilders, pro rugby players, real cop, real army and etc compete in simple games like run away with a ball and carry sandbags to a station for weight ins. Many flaws in the game, how can you put man vs women in a mud fight?? Are these only kind of games that the producers can think of? Low class. Are they're not embarrased to invite such a high level profile of contestant to compete such a simple games like this.?? Survivor or ninja warrior are way better, with just normal people competing. No need to invite high profile people in search for the top "physical" form crap. Very disappointed.
