in case any of you are worried about wooya bcs of this pic....

I think it's the SERRATUS ANTERIOR MUCSCLE and it is considered to be sexiest muscle on male

Some idol was known to have this muscle and it's due to the routine of working out.

These are baekhyun and xiumin of EXO who are also know to be having the serratus anterior muscle.

This prove that our seungwoo is doing good!! Eating healthy and is wroking out well.

Serratus anterior is one of the most forgotten or neglected muscle part. So the fact that wooya even able to develop this part of muscle means he's working out quite hard

as someone who work out, i know a bit about this. Well.. i'm not an expert but i don't think that wooya's showing rib cage indicated that he's not eating enough.

To workout and especially build some muscle, a decent amount of nutrition and protein is needed.

Therefore, no need to worry about it! I'm sure he's eating enough and healthy. As we know, wooya really likes to exercise so he must've known how important a decent healthy meal to develop his body and muscle

Btw, if any of you are nutrionist or someone who knows more info about this. Feel free to let other know more info abt this below or correct me if i tweet some mistakes on this thread!
