♬ CRAZY -Japanese ver.- – LE SSERAFIM

Before debuting with LE SSERAFIM, the members followed a rigorous fitness schedule. Their daily routine includes:

  • Jumping jacks (x100)
  • Burpees (x100)
  • Jump squats (x100)
  • Planking – twists, plank-to-shoulder taps (each 20 times)
  • Sit-ups (x75)

After completing these exercises, they would practice their choreography for hours and even repeat the workout post-dinner. It’s no wonder the LE SSERAFIM members have such sculpted bodies!

Among them, Kazuha (Nakayama Kazuha) stands out for her striking muscle definition, particularly her abs, which have even earned admiration from male idols.

She recently shared her workout routine which turns out to only consist of 10 simple exercises!

LE SSERAFIM Kazuha Abs Workout Routine

Shoulder Stretch

Before jumping into her abs workout, Kazuha starts with a simple shoulder stretch. She kneels on a yoga mat, places her hands flat on the floor, and reaches her right arm across her body to the left side.

As she presses her right shoulder towards the ground, she lets her head gently rest on the mat. She then switches sides and repeats the stretch. It’s a great way to ease into your routine and get your body ready for what’s ahead!

Body Stretch

After a good shoulder stretch, Kazuha moves into a modified body stretch. She supports herself with her left hand, bends her right arm beside her ear, and lifts her whole body upwards, stretching as far as possible.

This move works both the abs and back muscles, giving them a deep, energising stretch. Each side is held for 30 seconds, helping to activate and elongate the muscles for a more effective workout.

Back Muscle Relaxation

To work on her back muscles, Kazuha uses a yoga block. She places the block behind her back, gently lifts her hips, and rolls her spine over the block. This soothing move helps to release any built-up tension and loosen up the muscles, leaving her back feeling refreshed and ready for more.

Sideway Sit-ups

Her workout routine doesn’t skip the classic sit-up, a tried-and-true move for sculpting those abs. Lying on a yoga mat, Kazuha performs the sit-up with a twist—her legs are bent to the side and pressed flat against the floor.

This simple variation helps engage the abdominal muscles more deeply, providing a more targeted, effective workout for her core.

Sitting Crunches with Leg Raise

Kazuha’s next move combines a crunch with a leg raise. With her hands supporting her at a 90-degree angle, she keeps her hips grounded as she lifts her legs towards her abdomen.

She holds the position for 30 seconds, really feeling the burn in her core as she targets those lower abs for a stronger, more defined look.

Abdominal Training

Kazuha moves into an intense abdominal workout, lying flat on the mat and lifting her legs straight up. Using her core strength, she lifts her upper body off the ground and reaches for her legs.

This move really engages the abdominal muscles, helping to define and strengthen her core for that toned, sculpted look.

Leg Raise

Next, Kazuha targets her abs with a simple yet effective move. Lying on her back, she lifts her left leg straight up and touches it with her right hand, then switches sides.

Each side is held for 30 seconds, giving her abs a great stretch while also engaging the muscles for a deeper workout.

Bicycle Crunches

Kazuha kicks it up a notch with an advanced version of the bicycle crunch. With her hands supporting her upper body, she extends one leg at a time, holding each position for two seconds before switching sides.

This variation really challenges the core and helps tone both the abs and obliques for a more defined midsection.

Plank Twist

For the next move, Kazuha takes her plank to the next level by adding a twist.

In a standard plank position, she rotates her lower body, engaging her abdominal muscles even further. This added movement not only strengthens the core but also targets the obliques, giving her abs that extra definition.

Side Plank

The final workout in Kazuha’s routine is the side plank, one of the toughest exercises in her workout. Holding the side plank position, she lifts her bottom leg and touches her raised knee with the opposite elbow.

This move challenges her balance, strengthens the obliques, and works the entire core, making it the perfect finisher for a killer ab workout.
