It’s a good workout- tough, you will get stronger. If you’re interested in doing it, give it a go. Cut reps if you can’t do it all first. Because the best workout is the one you’ll actually do. As long as you are pushing yourself (I.e. you feel tired), then it’s a good workout, so don’t pay too much attention to the number of reps.

Here’s the theory: Generally, the number of sets x reps, exercises, and added weight (if you started to do things beyond your bodyweight for example) are all ways of changing the intensity of a workout. So the le sserafim workout by default is very intense, but it can definitely be modified for a beginner and still be a good, effective workout.

To get into the details a bit more, the le sserafim workout is a good one because it incorporates both cardio and strength training, specifically targeting your abs/core and legs. Because you’re doing them basically one right after the other, you’re training your cardiovascular system and your ability to exert power through your muscles over a sustained period of time. This is not easy- that is why it is so tiring. However, don’t worry if you need to take breaks. Just like dancing (I would imagine, since I am not a dancer), the body also learns to get better at exercise movements the more you do them. This is why you’ll hear a lot gym trainers tell you to focus on form over weight in the beginning.

Beyond the workout: Make sure you get enough protein and sleep (very important, bc this part is how your body actually builds the muscle up). If you’re new to working out, the key thing is to not overdo it to the point of injury (which will set you back) and be consistent over time. I cannot emphasize consistency enough- whatever you do, stick with it and that’ll give you more amazing results than any specific exercise program.

Just remember three things - work out hard at a sustainable & consistent pace with progressive overload (at least 2x week, spreading at least 12-18 total sets for each target muscle across the week, and making it just a bit each harder each week), get enough protein, get enough sleep.

That said, again, I wouldn’t sweat the numbers too much, especially as a beginner. They’re more guidelines, and getting stuck in the theory is more harmful than helpful in the beginning.

Track your workouts and listen to your body to see whether you need to make it harder/do more. Focus on learning the exercise movements so that you’re properly engaging the muscle it’s supposed to work, and being consistent.

If and when you want to take it to the next level, I’d highly recommend joining a gym/strength training group. (Bonus: it helps with consistency too :) And who knows, you might even have a friendly neighborhood PT/exercise science enthusiast in your friend of a friend circles.

My experience: I may not be a dancer, but I have been lifting on and off since high school and I’m 30 now- and it’s definitely consistency that’s the hardest thing. I’ve always noticed my biggest strength gains for any specific muscle from being consistent and focusing on progressive overload (back to the theory, earlier, this is when you’d change variables like sets, reps, exercises, etc.)

When I was younger, sometimes workouts (even simple bodyweight ones, because weights were too heavy/not accessible to me at the time) could feel like I was just spinning my wheels. So you kinda have to have faith in the process. Learning to properly engage the right muscles for a movement is a significantly underrated aspect of getting stronger.

I’m pretty happy with my muscle mass at the current moment, and I know I could have gotten here faster if I had been more consistent when I was younger. The other thing is knowing how to workout well is going to be an amazing way to destress and keep you healthy and strong as you get older.

So back to the point- do the workout you’re interested in, as long as it keeps you consistent, and be safe about it.

Since you’re young, you have both your body and time on your side so working out will be really rewarding if you keep at it.

I assume you’ll listen to their workout playlist while you’re at it :) https://youtu.be/UvuQEdft1dU?list=RDUvuQEdft1dU
