People practice yoga moves in a pool at a gym in Hangzhou, East China's Zhejiang province, on July 15, 2012. It is the first water yoga program in the city. Water yoga is safer than traditional yoga as the buoyancy and hydrostatic pressure of the water keep a person from pulling a muscle and getting injured, said a yoga coach.
