Seiji Yamaoka

Seiji Yamaoka has been in the fitness industry for 30 years and started his Pilates and Yoga chain in 2008. Yamaoka believes that the practice of exercise someone’s life, a healthy lifestyle and bring a quality life to those who seriously embrace it. Formerly a professional swimmer, he graduated with an MBA in business from Kenichi Ohmae Graduate School. Yamaoka has more than 14 years of Pilates teaching experience, especially in the Kaizen Pilates method.

In 2011, he developed a Pilates and Yoga specialty store chain (the introduction of a franchise system), and he successfully developed more than 15 studios in Tokyo, Japan. He believes that anyone can bring the values and benefits of Pilates to everyone. Therefore, he created a study module for it that can be studied by people who have never even heard of Pilates before. With this module, 60% of the instructors in the Pilates studio he develops are non-fitness professionals.

Currently, Seiji Yamaoka wants to bring the benefits and value of Kaizen Pilates, which has been developed in Japan, to Indonesians. In 5 years he wants to build 50 Pilates studios in Indonesia to make everyone in Indonesia feel the benefits of Pilates more widely.
