2018 Idol Star Athletics Bowling Archery Rhythmic Gymnastics Foot Volleyball Championships

The show features male and female K-pop entertainers, which competes in various sports competitions. To shorten the competition, every competition (except 60 m individual sprints and 4x100 relay) had only four teams involved in a single knockout. Men's footvolley made its debut to competition, replacing Male Team Aerobics.

Footvolley is the only 4-on-4 competition where teams are composed of members from different idol groups, and non-idol coaches provide instructions for two teams from the same bracket, so they have less likelihood of facing each other. Teams can bounce once before having to attack or defend, and touch between two teammates before hitting to the other side. Coaches can review twice, where all umpires and line judges (five members in total) will discuss the ruling, majority voting wins. First to 15 wins the round, best of three rounds wins.

Archery reverts to full 10-shot format for all rounds. To avoid confusion, however, the elected ace member from each team takes the final four shots, while the other two take three each.

Ten-pin bowling was filmed on a separate location on a separate date. The scoring has also been simplified. A strike is 30 points, a spare, depending on the first attempt, is from 10–19 points. Consecutive strikes and spares do not add together, and no bonus frames after a strike on the 10th frame, so the perfect score remains at 300 points.
