Dongheon, Yongseung, and Sim Jaeyoung chest workout

I heard that the three of them are same-age friends who became close after meeting back during Road to Kingdom.

Their bickering was really funny.

Yongseung suggested a chest workout that was at least somewhat manageable, so I started a "spicy" workout following Jaeyoung's routine.

Dongheon is proud to have appeared on his friend's YouTube channel, but

I honestly confessed that the workout itself was painful, haha.
