Les Mills takes on Workout for Water

New Zealand gym Les Mills is taking on Workout for Water - a challenge that helps raise funds for East African kids living in poverty.

On Saturday, one of the world's biggest fitness classes will take place in an effort to help children who need to walk up to 6km every day just to fetch water for their families.

Aziz Al-Sa'afin spoke to Dan, one of the programme directors at Les Mills.
