Momo Hirai: Diet Plan

Momo Hirai has a difficult time with diets; as I previously stated, she went through extreme dieting, which helped her lose 7 kg in a week, but it was not healthy. Momo talked about her experience in her V-Live broadcast, which you can read about in this Koreaboo article.

Momo described how she went a week without eating or drinking anything and went to the gym to lose seven kilograms in one week because it was a requirement for her job. Momo had only one ice cube, but she was already concerned that she would gain weight. Others thought she was going to die because she was so pale. However, once the day was over and Momo was relieved, she began eating excessively and gained 7 kg in one week.

So, no, it wasn’t healthy, and you shouldn’t try to follow that kind of diet plan in the future. However, she now follows a regular diet because, with the amount of training she does while dancing and other activities, she can easily consume three regular meals per day and not gain weight.

That concludes Momo Hirai’s diet plan.

Momo Hirai: Workout Routine

Momo is a k-pop idol, and as such, she must always stay fit and healthy in order for her career to continue. It’s something that every K-pop idol or actor must adhere to; in South Korea, you can’t be an idol if you’re bulky or chubby. Momo has taken extreme measures in her diet as well as a rigorous training routine to maintain her shape. So, let’s take a look at her workout routine to stay in shape.

Momo’s workout consists of the following:-


Momo, like any other member of a K-pop group, must be flawless when dancing in videos and live performances. It’s one of the most basic requirements of the skills required to become a K-pop idol, and it ensures that each singer has regular dance practice. Momo is not an exception; she attends regular dance practice sessions and trains for a couple of hours each week, which helps her maintain her weight and burn a significant amount of calories.

So you can also do a five-day dance workout and learn any dance style you want. If you don’t want to dance, you can do a cardio workout that burns at least 500 to 800 calories. Dancing is a more enjoyable way to burn calories and is less likely to bore you. It is, however, entirely up to you to choose which one you want to do.

Momo Hirai: Core Workout

Momo also does a lot of planks and plank twisters to keep her abs in shape, according to a few sources. Momo does nearly 50 twister and planks three times a day to keep her stomach flat and slim, according to the article. You can do that as well, but instead of just doing planks, you can do this routine once a day and be fine.
