Oiwa Toshiki


Starting from the injury he suffered and forcing him to give up on his favorite sport, Oiwa Toshiki tried to heal his injury with medical care and hospital but no one was able to find out the cause and solution to what he was experiencing. Until finally, after 7- 8 years, he discovered Pilates and he was very impressed with the changes that occurred in his body after trying Pilates and now he is currently a Pilates trainer.

Here in Indonesia Oiwa Toshiki wants to spread the value and benefits of Pilates more widely. He took a Pilates course without having tried it first. Therefore, he also wanted to convey this at Japan Conditioning Academy, anyone with any background can become a Pilates instructor.
