BtoB Sungjae’s Been Working Out And You Need To See What He Looks Like Now

BtoB’s Yook Sungjae has been working out and the results are drool-worthy.

Sungjae posted photos of his progress on Instagram that show impressive growth in his arms.

He even threw a coy pass at fellow group member Eunkwang, who also hit the gym hard for his musical.

Looks like we’ve got another BtoB member who’s been hitting the gym as hard as the rest of them.
