Every year, June 21 is the International Day of Yoga, designated by the United Nations.

In India, the birthplace of yoga, a rather special yoga class took place this year.

The core of yoga is breathing, but can you do it underwater?

People are lined up, striking poses in the blue water.

At an Indian Navy submarine training base, submarine crew members demonstrated underwater yoga.

The event was held to mark the International Day of Yoga, with about 40 crew members performing various yoga poses beneath the surface.

Watching them balance while overcoming the resistance of the water looks like a performance.

The Indian Navy stated that the event was intended to highlight the breath control and concentration skills required for submarine duty.
