"Dear Modiji, Happy International Yoga Day. I am writing this postcard while swimming in the pool. Fit India -- Shivaprakash, Mangaluru," read the handwritten note that drew attention at the event.

This pool workout is led by Sue Gisser, creator of H2yOga. Pool yoga allows you challenge your balance without falling and will also work to tighten your core. What a way to end the Summer!

To commemorate International Yoga Day, a group of 40 swimmers did yogasanas in Mangaluru City Corporation’s Mangala swimming pool on June 21 morning.
