Backpacks & Bodies: How to Carry It Right This School Year

By Khyl Orser, Strength & Conditioning Coach


Introduction: Back to School, Back to Back Pain?

It’s September, which means kids and teens are back in the classroom—and back to carrying heavy backpacks. While a backpack seems harmless, research shows that carrying too much weight or wearing it incorrectly can lead to back pain, shoulder discomfort, and posture problems. According to the American Academy of Pediatrics (AAP), children should carry no more than 10–15% of their body weight in their backpack. Yet many students regularly exceed that limit, creating unnecessary stress on their bodies.

Carrying too much load day after day can create unnecessary strain on a young body. It may show up as discomfort in the back, shoulders, or neck—or even as issues that seem unrelated elsewhere in the body. Kids are resilient and often won’t say much, but that doesn’t mean the stress isn’t there. The encouraging part is that with a few small adjustments, students can carry their books, laptops, and gear more comfortably, reducing strain and supporting healthier movement over time.


The Problem with Heavy Backpacks

Studies show that over 60% of children report back pain related to carrying their backpacks (Negrini & Carabalona, 2002). A poorly fitted or overloaded backpack can cause kids to lean forward, round their shoulders, or arch their backs unnaturally. Over time, this may lead to:

  • Muscle fatigue
  • Poor posture
  • Shoulder or neck pain
  • Lower back stress

For active kids and student-athletes, this can also carry over into sports performance and increase injury risk.


Signs Your Child’s Backpack Is Too Heavy

  • Complaints of back, neck, or shoulder pain
  • Red marks on the shoulders from straps
  • Leaning forward or changing posture while wearing it
  • Struggling to put on or take off the backpack

If you notice these, it’s time to make some adjustments.


Smart Backpack Tips for a Healthy School Year

1. Check the Weight

A simple rule of thumb: the backpack should weigh less than 15% of the child’s body weight. For example, a child who weighs 80 lbs shouldn’t carry more than 12 lbs in their pack. Weigh it at home with a scale to be sure.

2. Wear It Right

  • Use both shoulder straps (not just one).
  • Adjust straps so the backpack sits snugly against the back, not hanging low.
  • The bottom of the pack should sit just above the waistline.

3. Pack Smart

  • Place heavier items (like laptops or textbooks) closer to the back.
  • Use compartments to distribute weight evenly.
  • Remove unnecessary items—many kids carry more than they need.

4. Choose the Right Pack

  • Look for padded straps and back support.
  • A waist or chest strap helps spread the load.
  • A lightweight bag reduces starting weight.

5. Encourage Breaks

If possible, encourage kids to use lockers, desks, or cubbies to store books instead of carrying everything all day.


Building Stronger Kids Beyond the Backpack

Backpacks aren’t going away, but strong, resilient bodies handle them better. Adding strength and conditioning to a child’s routine can:

  • Strengthen postural muscles
  • Improve endurance
  • Build core stability
  • Reduce aches from daily carrying

Something as simple as body weight exercises (squats, planks, push-ups) or youth strength training under professional guidance can make a big difference.


Final Thoughts: Small Changes, Big Impact

Backpacks are part of everyday school life, but they don’t have to be a source of pain. By choosing the right pack, packing it smartly, and reinforcing good habits, we can help kids move well, stay comfortable, and stay focused on learning and play.

As parents, coaches, and educators, it’s our job to support healthy routines. Protecting young backs today builds stronger athletes and healthier adults tomorrow.
