The feature of the "Dr. Stretch" service is the original technology "Core Balance Stretch" devised by former Major League Baseball trainer "Motonori Yamaguchi". One-on-one stretching by a trainer approaches muscles that cannot be stretched by one person, and fundamentally eliminates discomfort such as "shoulders and hips". In a store like a soccer stadium with stadium seats or grass, you can get a feeling of exhilaration like after sports just by taking a stretch while lying down.
