Global fitness brand Les Mills is teaming up with UNICEF to create a one-day exercise event, with money raised helping children and their families access safe water and better health care.

Together with its 19,000 gym partners and 130,000 instructors, Les Mills and UNICEF will coordinate Move the World on World Children’s Day (18 November).

Unsafe water can lead to weakness, malnourishment and a susceptibility to water-borne diseases, which are among the leading causes of death in children under five.

“Access to water is a fundamental right and a life saving intervention. When children have access to safe water, sanitation and hygiene, they have more than just life, they have a chance to be healthy, to gain an education, and to have a brighter future,” said Jonathan Veitch, deputy director of the national committee relations, private fundraising and partnerships division at UNICEF.

Dr Jackie Mills, Les Mills International creative director, added: “We are absolutely committed to making a difference to the lives of children around the world and we’re honored to be an official partner of UNICEF.”
