Backpack posture — Bone & Muscle Mountains · Body Quest
Your backpack is heavy today. Make the choices that look after your back. Ergonomists design school bags with padded straps and waist belts to spread the load.
Your task
Make the best choices.
- A common guide: a backpack shouldn't weigh more than about 10–15% of your body weight — but we don't weigh anyone here.
- A fictional journey, not medical advice. If you feel unwell, talk to a trusted adult or a health professional (Portugal: SNS 24 — 808 24 24 24; emergency: 112).
- Every body is different and every body is valid. Nothing about you or your health is collected.
Score
- Body knowledge — You understood how this part of the body works.
- Healthy habits — You chose habits that help your body.
- Safe & ask for help — You stayed safe and knew when to ask a trusted adult.
