My cousin’s child is 10 years old. He asked me: “Can my kid do push-ups? Will it affect their height?”
I asked him: “Why do you think it would?”
He said: “I read online that strength training stunts kids’ growth.”
This is one of the most widespread fitness myths.
As a fitness professional and father of two, today I’m sharing some scientific facts about youth exercise—for parents who care about their children’s health.
1. Strength Training Won’t Stunt Your Child’s Growth
This is parents’ #1 concern.
The truth: appropriate strength training won’t affect height development.
This myth comes from confusing “strength training” with “weightlifting.” High-intensity pressure in weightlifting (especially behind-the-neck presses) can potentially damage growth plates.
But bodyweight-focused resistance training (push-ups, squats, rows, etc.), with proper form, is safe for growth plates.
The American Academy of Pediatrics (AAP) clearly states: strength training is safe for children 8 years and older with proper supervision.
Key points: supervision, proper form, appropriate intensity.
2. When Should Kids Start Exercising?
Answer: The earlier the better, but in age-appropriate forms.
Motor development windows:
- Ages 2-5: Fundamental movement skills—running, jumping, throwing, catching
- Ages 6-8: Begin introducing structured physical activities
- Ages 8-12: Can start learning movement skills and basic strength concepts
- Age 12+: Can begin more systematic strength training
But an important point: children under 12 don’t need “formal” strength training. Playing, climbing trees, swimming, chasing each other—these are the best exercises for this age.
3. The Best Way to Make Kids Hate Exercise
Many parents unknowingly make children hate exercise through these methods:
Forcing: “You must run 30 minutes every day” Comparing: “Look at Xiao Ming, he runs so actively” Punishment association: “You can only exercise after finishing homework” Over-focusing on results: “What place did you get in running today?”
All of these turn exercise into a “task” or “punishment.”
Kids are naturally active. If your child hates exercise, usually the adults’ approach is the problem.
4. How to Make Kids Love Exercise
1. Turn Exercise into Play A 5-year-old doesn’t need “to go running.” They need “let’s play tag” or “let’s race to that tree.”
2. Let Them Choose Give options, not commands. “Do you want to play basketball or ride your bike?” This gives them autonomy.
3. Focus on Process, Not Results “You looked so happy while running” is much better than “What place did you get?”
4. Be a Role Model If kids always see parents sitting and not moving, why would they want to move?
5. Control Your Reactions When kids get hurt or perform poorly during exercise, your reaction gets remembered. Next time they’ll fear your reaction and start hating exercise.
5. Youth Exercise Safety Essentials
Supervision Is Key Before age 12, all strength training should be under adult supervision.
Focus on Form, Not Weight The goal of children’s strength training is learning movement patterns, not lifting weights. Bodyweight training is primary.
Mind Recovery Teens recover faster than adults, but that doesn’t mean they don’t need rest. Ensure they get enough sleep.
Avoid Over-Specialization Don’t let kids train only one sport. Diverse movement experiences reduce injury risk and promote well-rounded development.
6. Screen Time and Exercise
This is the headache for many parents.
Research shows:
- Children with more than 2 hours of daily screen time have significantly lower activity levels than peers
- But reducing screen time alone doesn’t increase exercise—you need to provide alternative activities
The solution isn’t “no screens,” it’s “what’s more fun than screens outside”.
Take kids to the park, play with neighborhood children, join sports clubs—make exercise more appealing than screens.
7. What If Your Child Says “I Don’t Want to Exercise”?
This confuses many parents.
First, accept the feeling. Forcing only makes it worse.
Then, explore the reasons:
- Is the exercise too hard or too easy?
- Have they been teased or had a bad experience?
- Is it just because electronic devices are more fun?
Find solutions based on the cause:
- Too hard → Lower difficulty, let them experience success
- Bad experiences → Find lower-pressure forms of exercise
- Screens more fun → Make exercise “game-like” too
Finally, remember: kids don’t need to become athletes, but they need to move.
The goal isn’t raising elite athletes—it’s raising lifelong movers.
The Bottom Line
Keys to youth exercise:
- Strength training won’t affect height—provided form is correct and there’s adult supervision
- Earlier is better—but in age-appropriate forms
- Don’t turn exercise into a task—make it a game
- Focus on process—not results, not rankings
- Be a role model—kids imitate you
End goal: not making kids the best athletes, but ensuring that in 20 years, 40 years, 60 years—they’re still willing to move.
