RED VELVET, proposed a new type of event "Knee Kicken".

* No need for a worry of injury.

* In the popular special programs for On Lunar New Year, and Old Bon Festival "Idol Athlete Games", many injuries occurred and "basketball" and "futsal" were cancelled.

* The competition events adopted instead are "aerobics" and "bowling".

* At the preliminary recording of the 15th, two people were injured in "aerobics" as well..
