Resolve Minor Ailments for People Over 50 with 5-Minute Daily Workouts: 'Healthy and Flexible Muscle Training for Staying Youthful: Body Maintenance Starting in Your 50s'

Ultimate Life Inc., which operates the 'GronG' protein brand, will release the book 'Healthy and Flexible Muscle Training for Staying Youthful: Body Maintenance Starting in Your 50s' by its employee, trainer and acupuncturist Shuhei Maeda, on June 19, 2026, via KADOKAWA Corporation. The 50s is a period when physical decline is often felt, partly due to decreased muscle mass. To help even exercise novices stay consistent, this book presents carefully selected 'flexible muscle training' exercises that can be done in just 5 minutes a day without special equipment. It also features exercises tailored to common complaints among those in their 50s, such as 'back pain' and 'difficulty with stairs,' proposing muscle training as a form of 'body maintenance'.
