What is the "Le Sserafim" workout?

So, what's the Le Sserafim workout all about? The Kpop group explained it perfectly in a TikTok video: "It was a workout we did when we were preparing for the group. It was like our training workout. It was very strenuous. It was 100 jumping jacks as a warm-up, and then 100 burpees, and then three sets of four different plank exercises with 25 reps and stuff. It was very intense. And we did that like, for two hours, twice a day. But, it helped us build stamina for our choreo."

The full list of exercises in this routine includes:

  • 100 jumping jacks
  • 100 burpees
  • 2 sets of 10 jump squats
  • plank crawls (for the duration of the song)
  • 2 sets of 10 plank up and downs
  • 2 sets of 10 plank twists
  • 3 sets of 25 crunches

This routine may not be for the faint of heart, but it's chock-full of benefits. "The Le Sserafim workout is effective for weight loss, strength, and stamina due to its comprehensive structure.
