How many star jumps?
You will count comfortable star jumps during a short interval. Keeping the movement controlled can be harder than increasing the count, so stop before tiredness changes your landing.
- Move
- Starter
- About 10 minutes
Grown-up needed: yes for checking the space and supervising movement
This page adds a grown-up and a clear nonslip floor to what the film lists, so follow the page.
What you need
- A clear nonslip floor
- A timer
- A grown-up
The rule
Arms and legs right out each time.
How to do it
- Ask a grown-up to check that the space suits gentle jumping.
- Stand comfortably with room around your arms.
- Set a timer for up to thirty seconds.
- Make comfortable jumps opening and closing arms and legs.
- Stop early if the movement feels uncomfortable.
- Rest and record your own count without comparing it with the film.
Why it works
Moving muscles use energy, and the body adjusts circulation and breathing to support that work. Your heart may beat faster during exercise to move blood carrying oxygen and nutrients. The exact response depends on the person and the effort, so a short jumping count does not measure fitness or health. Controlled landings also involve muscles slowing the body’s downward movement. Resting afterwards lets you observe the change without treating a faster heartbeat as a score to maximise.
Make it harder
- Repeat only after a comfortable rest.
- Compare a slower controlled pace with your first pace.
- Explain why a higher count does not necessarily mean better control.
Ask Taz
- Why can my breathing change when I move?
- Why do muscles help slow a landing?
- Why is a jump count not a health score?
For grown-ups
Use this only when the child is comfortable with ordinary jumping, and let them stop whenever they choose. Clear furniture, pets and loose items from the space. A non-jumping movement can be a separate adaptation without claiming it follows this exact rule. Ask at dinner: “What changed when you focused on control rather than count?”

Questions parents ask
Does the child need to reach the film’s target?
No. The film shows an example, not a required performance. Begin with a short comfortable attempt and stop whenever needed. The useful result is a description of what happened, and the stated time estimates preparation and discussion as well as the activity.
Can we adapt the movement?
Yes. Choose a comfortable version with a grown-up, or discuss the film instead of doing the action. Say clearly when the adaptation changes the stated challenge rule. Avoid making the activity faster, longer or less stable simply to make it harder.
Do we need to share a video?
No. Talking about the attempt at home is enough. Follow the privacy line above for any optional sharing.
