Globally, nearly 450 million children are living in areas of extreme water vulnerability. But through Les Mills’ partnership with UNICEF, we all have the opportunity to put our energy to good use and help change children’s lives.

It’s hard for us to imagine a world where we’d have to walk hours on end to fill up our water bottles, even then not knowing if it was safe to drink. Sadly, that’s the reality for 1.42 billion people globally, 450 million of them children. Living in areas of high or extremely high water vulnerability, it is the children who suffer most. Water-borne diseases are among the leading causes of death in children under five. Many children miss out on play and education as they spend their days traveling long distances just to get water. There’s no rest day. It’s seven days a week, 52 weeks a year.

In recent years the United Nations Children's Fund (UNICEF) has been working to improve water, sanitation and basic hygiene in these areas of vulnerability. When communities have access to safe water, it creates opportunities for education, health care, protection, and nutrition too.

As part of the ongoing effort to fund this aid work, Les Mills has partnered with UNICEF to raise awareness and money to help create a world where every child survives and thrives.

The work started back in 2017 when Phillip Mills, Les Mills founder and CEO, and Rachael Newsham, Les Mills Program Director, travelled with UNICEF to a refugee camp in South Sudan. Seeing the scale of the problem first-hand and meeting the resourceful and resilient people there was an extremely powerful experience for both, reinforcing their desire to make a difference.

“These people are living under incredibly difficult conditions, but trying to create as normal an environment as possible for their kids to grow up in.” says Phillip, “It’s heart-rending.”

“They have nothing, they’re in fear for their lives … and they urgently need help in the form of clean water, food and medical care.”

In 2019 and 2020, Workout for Water raised almost US$600,000, which was used by UNICEF to upgrade the water supply of the remote Yelam Gej and Lega villages in Ethiopia. This new solar-powered system now provides water for one healthcare center, two schools, and 280 households. It’s also connected more small villages to have better access to water without having to walk and queue for hours.

With access to clean, safe, and sustainable water, the children of these communities can grow up healthy, strong, and safe from waterborne diseases. They also have more time to spend on study and playtime now that they don't need to walk for hours each day to collect water.

In 2024, Les Mills and UNICEF are bringing back Workout For Water and the funds raised will support UNICEF’s full spread of life-changing Health, Education, Nutrition, WASH (Water, Sanitation, and Hygiene), and Protection programs.

It is one of the key drivers of deaths among children under 5 from preventable diseases.'
