Exercise for ages 4-5
By the time your child is 4-5 years old they have developed their motor skills enough to control the basics. At this stage they are working on further improving balance and increasing their physical skill set.
Though an hour is the minimum required amount of physical activity in this age group up to 2 hours of exercise is beneficial. The exercise should be split between an hour of structured activity that you plan and an hour of unstructured activity that the child is able to decide on.
