Prince William said 'Namaste' to a new type of stretching before taking part in a charity polo match on Sunday (May 29), engaging in a number of yoga moves that definitely turned heads. The third-in-line to the throne laughed as he warmed up for the game.

Under the watchful eye of a professional, the prince struck a number of poses with his teammates wearing a blue shirt and his white polo jeans. He also ditched his shoes, revealing his dark socks.

Among the stretches William tried out was cat-cow pose, which stretches the spine and prepares the body for activity, as well as some general quad and hamstring stretches to prepare for the match.

It’s not known what prior experience William has with yoga, although Kate is a huge fan of the activity after taking part in pre-natal yoga session before Prince George's birth.

Although Prince Harry was nowhere to be seen during the warm-up session, the 31-year-old joined his brother to play the polo match. However, he seemed to be suffering from some back trouble and was seen getting some deep heat treatment sprayed onto his lower back. It didn't seem to hold him back, however, and the Invictus Games patron gave it his all as he did battle on the polo pitch.

The brothers are taking part in several matches this summer to raise money various charities they support, including Sentebale, the charity Harry set up in 2006 in memory of his late mother Princess Diana, which aims to help children and vulnerable young people in the African counry of Lesotho.

The brothers have been playing in charity polo matches since 2007, and have so far raised an incredible $18 million for charity.
