A school-aged child should be getting around 60 minutes of physical activity every day.
Unless you walk, cycle or scoot to school, it can be difficult to fit that amount of exercise into a regular week day, particularly when the weather is as horrible as it has been over the last couple of weeks.
The good news is that the 60 minutes do not need to be completed in one continuous chunks, and they can be indoors.
Instead of doing the same physical activity over and over, children will find exercise much more fun if you set up a series of physical games around the house, and limit the time on one game to just five minutes, much like a circuit training session in a gym. You can set a timer to sound when it's time to switch activities, or put on some music and change at the end of each song.
It's important to start with some gentle warm up exercise, which you repeat at the end to cool down. In between you can select any mixture from the menu of exercise options below. Make your circuit-time add up to around 20-30 minutes.
1. Jump rope.
2. Count how many jumping jacks you can do before you have to stop.
