One hundred competitors (89 official fighters, 5 Assist Trophies, and 6 requested fighters), all known for their well-developed physical attributes and physique, go head-to-head against each other in various individual and team challenges, or 'quests' of strength, balance, agility, endurance, strong willpower, and strategy. The competition is formatted like a tournament. Following each quest, participants are eliminated until only one remains to win the prize money of ₩300 million. Every participant has a plaster cast of their torso on set; if they are eliminated after a quest, they have to destroy the cast with a sledgehammer.
The show has often been compared to Squid Game, a 2021 South Korean survival drama television series, for their language and competition-elimination format similarities.
