Why do we need exercise?
We need exercise because moving makes our muscles, heart and bones strong.

Pip’s answer
- We need exercise because moving makes our muscles, heart and bones strong.
- When you run, your heart beats fast and gets better at pumping blood.
- Muscles get stronger each time you use them, like when you climb stairs or swim.
- Ooh, moving your body even helps you feel happy and sleep well at night!

For grown-ups
Physical activity strengthens the heart, lungs, muscles and bones, and helps with balance and coordination. It also improves mood, sleep and concentration. Health guidelines suggest children aged 5 to 17 get at least 60 minutes of moderate to vigorous activity daily.
Ask your child: What's your favorite way to move your body?
