Physical 100‘s Kim Sik wowed fans after he pushed his body to the limits by holding up a large 50 kg (110 lbs) boulder over two hours competing against car dealer strongman Jo Jin-hyeong. The two competed in Quest 4’s Punishment of Atlas competition and Kim Sik almost made it to the finals. The skeleton coach graciously let his mentee and Olympic gold medalist Yun Sung-bin compete in The Punishment of Sisyphus because he thought the younger athlete had a better shot at winning the 300 million won prize.
Before getting eliminated near the end of the show, Kim Sik defeated his opponent in Quest 1’s one-on-one death match. He then joined Yun Sung-bin’s team for Quest 2’s Moving Sand competition they successfully won. After that, they allied Ma Sun-ho‘s team to get second place in Quest 3’s ship-dragging competition. Quest 4 was the end of the road for Kim Sik, but here’s everything viewers need to know about the fan-favorite.
