Exercise in Children and Young People

Children and young people aged 5 to 18 should average at least 60 minutes of moderate to vigorous activity a day across the week, and the under-5s have their own targets by age.

Activity in childhood supports healthy growth, strong bones and muscles, movement skills, mental health, and concentration and learning. Activity peaks around school entry and declines through adolescence, boys are more active than girls at all ages, and activity levels may track into adult life. This page covers the UK Chief Medical Officers (CMO) guidance from birth to 18, how it compares with World Health Organization (WHO) guidance, and the practical points for clinicians.
