A book containing the wisdom gained from a 50-year-old man's 10-year journey of "intense" exercise has been published, drawing significant attention. The author, Kim Hee-jae, South Korea's only Edo Portal Method Movement instructor and influencer, shares his secrets to achieving physical abilities far surpassing those of a healthy 20-year-old.

Kim Hee-jae, a former senior executive at a German logistics company, was shocked by the sudden death of a close friend and decided to embark on a new life. He has since dedicated himself to finding ways to live and age healthily, retiring from his company in his mid-40s. For the past decade, he has consistently invested 5-6 hours a day, six days a week, in exercise.

Kim Hee-jae emphasizes the importance of mastering "letting go," "holding on," and "finding balance" in life. He encourages readers to constantly try new things, stating, "Just as you build muscle through exercise, build mental strength through challenges."

Kim Hee-jae's impressive physique and powerful workout videos, which shame those who make excuses like, "I'm in my 40s, I'm in my 50s," perfectly complement his "straight-talking" advice, captivating readers.

If you're hesitant to start exercising because it seems too difficult, encountering this book is a stroke of luck. This book is a must-read not only for those who have experienced a decline in physical activity and motivation in their 40s or have become lazy in their 50s, but also for those in their 20s and 30s who want to get healthy without "distracting thoughts."
