”FTISLAND” Lee HONG-KI, rowing machine at the gym before the concert? …“Just a little pull before going to the concert”

Lee HONG-KI of the group FTISLAND has released a photo of himself before the concert. On the 30th, Lee HONG-KI posted on his Instagram
I posted a video in Stories with the caption, ``Take a moment before going to the concert.''
The video released shows him rowing on a rowing machine wearing a T-shirt and denim pants.
It looks a little humorous to see Lee HONG-KI gritting his teeth and pulling back.
On the other hand, "FTISLAND" to which Lee HONG-KI belongs will be held for two days on December 30th and 31st.
"2023 FTISLAND CONCERT 'FTSODE'" will be held at COEX Auditorium in Gangnam-gu, Seoul.
