As for how he started doing yoga, Le said: "I didn't start doing yoga until I practiced all the courses and equipment in a fitness center after retirement, because it was embarrassing for me to learn yoga whose participants are almost female."

Le began practicing yoga when he was 63 years old, and he fell in love with yoga half year later, though he felt pain at the beginning.
