I Tried the LE SSERAFIM Workout Every Day for a Month — Here's What Happened

Le Sserafim is a popular girl group from South Korea known for their athletic performances and toned physiques. A while ago, some of the members shared details about their workout routines. Seeing their defined abs and six-packs inspired me to give their workout a try. I wanted to see if following a similar routine could help me build a stronger core and work toward that lean, toned look myself.

I have to admit—I was genuinely surprised by how difficult it was. The first workout made me feel like I was training for some kind of special mission. Every exercise pushed me harder than I expected, and I was completely exhausted by the end.

Fortunately, it got easier over time. As my fitness improved, the workouts seemed to fly by, and I was able to keep up much better.

I stuck with the routine every day for an entire month. When I stepped on the scale afterward, though, I was surprised to see that I hadn't lost any weight. My weight stayed almost exactly the same at the end of the month.

At first, I was disappointed. I had assumed that such an intense workout would automatically lead to weight loss. But despite the lack of change on the scale, I don't regret doing it. It was a great workout that challenged my body, improved my endurance, and made me feel stronger. I'm glad I committed to it for the health benefits alone.

The experience also taught me an important lesson: exercise is only one part of the weight-loss equation. Nutrition, overall calorie intake, and consistency play just as important a role. Even a challenging workout won't necessarily result in weight loss if you're consuming enough calories to replace what you burn during exercise.

Looking back, I realized I had focused almost entirely on the workouts and paid very little attention to my diet. If your goal is to lose weight, combining regular exercise with a balanced diet and a sustainable calorie deficit is generally much more effective than relying on workouts alone.

Here's the Workout:

Jumping Jacks: 100

The jumping jacks can be tough on your knees, especially if you're older or have joint issues. If that's the case, you may want to modify the movement or choose a lower-impact alternative.

I also found that for any workout involving a lot of jumping, wearing a supportive sports bra is essential. It helps reduce movement, improves comfort, and allows you to focus on your workout without unnecessary discomfort.

It can be difficult to keep your breasts supported during high-impact exercise if you're not wearing the right sports bra. A well-fitting, supportive sports bra makes a huge difference in both comfort and confidence.

I highly recommend investing in a quality sports bra, even if it costs a little more. A good one can last for years, provide the support you need during workouts, and make exercising much more comfortable. For me, it's one of the best fitness investments you can make.

If you're running or doing workouts with lots of jumping, choose a high-impact sports bra. It's designed to provide maximum support and reduce movement during high-intensity exercise.

Burpees: 4 × 25

Doing burpees immediately after the jumping jacks is incredibly challenging because you're already out of breath.

Try not to space your workout out too much. Taking breaks is perfectly fine, but if you rest for too long, it can be difficult to get back into the routine. Personally, I take about a one-minute break between each set and around five minutes between each exercise. That gives me enough time to recover without completely losing my momentum. I doubt the members of Le Sserafim took breaks that long, though!

Jump Squats: 4 × 15

This section focuses on jump squats. Fortunately, the number of reps isn't overwhelming, so it becomes very manageable once you've adjusted to the routine. By this point, your legs will probably be feeling tired, but with practice you'll be able to complete this section without too much trouble.

Plank Crawl: One Full Song

For this part of the workout, I decided to push myself a little harder even though I was already exhausted.

The original routine used "Fearless" by Le Sserafim, which is about 3 minutes long. Instead, I used "Super Shy" by NewJeans, which is about 3 minutes and 20 seconds. Looking back, my song choice definitely shows how long ago I completed this challenge!

Russian Twists: 4 × 25

By this stage, my abs were definitely burning. Maintaining good form became much more important than trying to rush through the reps. Sometimes, I'll switch things up and do plank twists instead for a bit of variety. Both exercises challenge your core, so it's a nice way to keep the workout from feeling repetitive while still targeting your abs.

Plank Up and Down: 4 × 25

This exercise really challenged my shoulders and core. Even though I wanted to stop, I found that breaking each set into smaller goals made it easier to finish.

Leg Raises: 4 × 15

My lower abs were already fatigued by this point, so the leg raises felt much harder than they looked. Slowing down the movement helped me maintain proper form instead of relying on momentum.

What kept me going was thinking about the end goal. Every rep made me imagine building stronger, more defined abs, and that motivation helped me push through the burn. Even when I wanted to stop, reminding myself why I started made it easier to finish the set.

Crunches: 4 × 25

Thankfully, crunches were the final exercise. By this point, my core was completely exhausted, but it felt satisfying to finish the workout.

It also depends on which type of crunches you choose to do. I personally did full sit-ups because I find them easier than traditional crunches. If regular crunches are more comfortable for you, you can stick with those instead. The important thing is to maintain good form and keep your core engaged throughout the movement.

Final Thoughts

Overall, I enjoyed this challenge much more than I expected. While I didn't lose weight during the month, I became fitter, my endurance improved, and I proved to myself that I could stick with a demanding routine.

If your goal is simply to become more active and strengthen your core, I think this is a fun workout to try. However, if your primary goal is weight loss, don't expect the workouts alone to do all the work. Pairing exercise with good nutrition and a sustainable calorie deficit will have a much bigger impact than relying on exercise by itself.
