Seo In-guk Workout Routine

Seo In-guk is a singer and actor known for his singing career but went global for acting in movies and TV shows. Seo In-guk is getting known more and more as he grows as an actor. Besides the acting part, Seo In-guk is also quite famous for his weight loss journey and being in a lean and ripped body shape. As we always know, K-pop before and even now focuses on making idols look leaner and skinner.

That’s what happened with Seo In-guk when he was trying to be an idol, and he had to lose a lot of weight in the K-pop industry. After that, when he got the movie No Breathing, Seo In-guk again lost weight from 76 kg to 65kg in a couple of months, where he went through rigorous training and diet. Oh, by the way, he is right around 6 ft, so 76 kg is not even an unhealthy weight for him.

However, as the Korean industry always focuses on boyish looks and lean personality, it always makes artists go to the next level to lose weight. Now, about his workout during that time, Seo In-guk was constantly training in the gym, focusing on different workouts like lots of cardio and some mixed weight training. So I’m guessing even though he doesn’t have to lose so much weight now, he still maintains the gym workout to stay in shape. So to get a body like him, I would suggest doing at least four to five days of workout routine and getting a good diet.
