The Japanese 5-Minute Trick for Rock-Hard Abs (No Crunches Needed)

What if getting abs didn’t mean endless crunches, planks, or time spent sweating at the gym? For thousands of people in Japan—and now around the world—one simple five-minute stretch has changed everything. Invented by Dr. Toshiki Fukutsudzi, this method uses nothing more than a rolled towel to target deep core muscles and realign the spine.

Forget high-tech gear or extreme workouts. Here, all you need is a mat, a towel, and a few minutes each day. People who struggle with stubborn belly fat, poor posture, or low back pain say this Japanese hack feels almost like a shortcut.

How to do the Japanese towel method for a flatter belly?

Let’s get practical. Here’s exactly how you can try the Fukutsudzi technique at home:

Step Action What’s Happening
1 Lie flat on your back, knees straight Your spine relaxes against the floor
2 Place a rolled towel under your lower back, at the navel This creates a gentle arch and stretches the core
3 Stretch your legs out, let your big toes touch Aligns the pelvis and encourages deep muscle work
4 Raise your arms above your head, pinkies touching the floor Opens up the ribcage and lengthens your torso

Why does it work so well? The science behind the stretch

What’s unique here is how this method resets your posture while working the muscles you can’t see—those deep core stabilizers. Unlike traditional ab exercises, you don’t strain your neck or force movement. Instead, the gentle stretch encourages your abdominal muscles and lower back to engage naturally.

Regular practice helps flatten the stomach, improve digestion, and even relieve back pain. Some report feeling taller and lighter, with more energy in their daily lives. This method is especially useful for anyone who dislikes the gym or struggles with classic workouts.
