If you’re into Asian pop music from South Korea, then Wonho will be a familiar name to you. But the same should be true if you follow celebrities that go through huge body transformations.

And that’s what Wonho did when he joined Monsta X and then dedicated a load of time to going to the gym and working on every part of his body.

The K-Pop idol and former Monsta X member took it so seriously that his band members often spoke about how he even heads to the gym when they are on a busy tour schedule.

So, I spent a couple of weeks researching interviews and his social media accounts to see how he achieved this.

Quick Summary

  • Bicycle kicks, lateral raises, side curls, leg extensions, hamstring curls, squats, cycling warm-ups, Arnold presses, and chest flys are an example of the workouts Wonho performs.
  • Wonho diet comprises red meat, vegetables, white rice, chicken, asparagus, fish, sweet pumpkins, and fruits.
  • Pre-workouts, and fat burners are the supplemnets Wonho takes.

Wonho Stats

  • Born: March 1, 1993
  • Height: 5’8”
  • Weight: 170 lbs

He was a star with Nu Boy and then Monsta X, where he gained most of his early fame. Then his body took over, and he became a huge solo star with millions of followers.

“I never thought life could get any better but I was wrong, so wrong.”

- Wonho Monsta X Lyrics

Wonho Workout Routine

This Wonho workout routine is heavily focused on the upper body, especially to get those well-defined abs.

All of the below exercises are three sets of 8-10 reps except for the ab workouts, which are three sets to failure.

Saturday/Sunday: Recovery

Your muscles will feel tight after such a workout week, and the best thing you can do is go for a few walks or a swim to keep them loose. Also, consider a foam roller to massage your muscles and help improve blood flow to get you ready for the next workout routine [1].

What’s Wonho’s Diet Plan Like?

Chicken breast and vegetable meal

Wonho’s diet plan focuses on getting plenty of vitamins and minerals through natural food, so in a nutshell, Wonho eats a healthy diet.

He also makes sure he drinks warm water with salty food, as he says this can help reduce water retention. I couldn’t confirm this theory, but it’s an interesting approach.

  • Breakfast:  Red meat, White rice, Vegetables
  • Snack:  Protein shakes with chicken and asparagus
  • Lunch:  Fish, White rice
  • Evening meal:  Red meat, Sweet pumpkin, Vegetables

What Supplements Does He Take?

In addition to the Wonho diet plan, I would suggest that you consider these supplements to complement your exercises.


A natural pre-workout supplement can give you a small boost in performance for your muscles. You won’t turn into Wonho overnight, but you’ll be able to do a few more reps or sets in each workout to get to your goal faster.

Fat Burner

Wonho obviously has a very low BMI. And balancing low fat reserves with bulking can be difficult. With a natural thermogenic fat burner for men, you can boost your metabolism to achieve a lower fat percentage like Wonho [2].

Are You Ready To Train Like Wonho?

Even if you can’t see yourself as the next Monsta X member, there’s every reason to aim high for your goals and see if you can get a ripped physique and abs like Wonho.

The above exercises won’t be easy, and you’ll have to take a careful look at your breakfast, lunch, and dinner to get the right nutrition to support them.

But if you stick with it and add a good fat burner into your diet plan, then your physique has the right conditions to change a lot quicker.

These supplements are not an excuse to eat junk food, but with a strict diet and rigorous exercise, you’ll get rid of that fat considerably faster.
