If you’re a parent researching whether strength training is safe for your kid, you’re in good company. It’s honestly one of the most common questions we get from families, and it’s a totally fair one. The good news? The answer is clear, well-researched, and overwhelmingly positive.
Let’s walk through what the science actually says, bust the biggest myths, and show you what proper youth strength training looks like when it’s done right.
What the Research Says
Every major sports medicine and exercise science organization in the world supports supervised youth strength training. The National Strength and Conditioning Association (NSCA), the American Academy of Pediatrics (AAP), and the American College of Sports Medicine (ACSM) have all published position statements affirming that properly designed and supervised resistance training is safe and beneficial for children and adolescents.
The most persistent myth, that lifting weights will stunt a child’s growth, has been debunked over and over in peer-reviewed research. There is zero evidence that age-appropriate strength training damages growth plates or limits height development. In fact, the controlled forces placed on bones during resistance training actually promote healthy bone density and skeletal development. So no, your kid is not going to shrink.
Key findings from current research:
- Youth strength training has one of the lowest injury rates of any organized sport when properly supervised
- Resistance training improves bone mineral density during critical growth years
- Young athletes who strength train show reduced injury rates in their primary sport by up to 50%
- Strength training improves coordination, body awareness, and motor control in developing athletes
The research is not mixed or uncertain. The consensus is clear.
The Real Risk: NOT Training
Here is what most parents don’t realize: the athletes most at risk for injury are not the ones who strength train. They’re the ones who don’t.
When young athletes play their sport year-round without any structured physical development, the body absorbs enormous repetitive stress without the strength, stability, or durability to handle it. The result is a growing epidemic of overuse injuries. Stress fractures, tendinitis, ligament tears, and chronic joint pain in athletes who are sometimes as young as twelve or thirteen.
We wrote about this in our post on the missing piece in youth sports development. The analogy we use is a race car: sport skills are the driver, but physical development is the engine. Without that engine, even the most skilled driver will eventually push the car past what it can handle.
The athletes most at risk are not the ones who strength train. They are the ones who don’t.
When Can Kids Start?
There is no single magic age, but the general guidelines are well established. Children as young as seven or eight can begin bodyweight and movement-based training. Think squatting, lunging, pushing, pulling, and learning how to land and decelerate safely. Basically all the things kids should already be doing on a playground, just with a little more purpose.
By ages eleven through eighteen, athletes can progress into structured strength programs that include resistance training with external loads. This is the age range where we see the biggest window of opportunity for building a physical foundation that protects against injury and accelerates sport performance.
It’s not about age alone. What matters most is maturity, coaching quality, and progressive programming. A well-coached twelve-year-old training with proper supervision is far safer than an unsupervised teenager maxing out on a bench press they saw on social media.
Our youth performance program is designed specifically for athletes ages 11 to 18, meeting them exactly where they are developmentally and building from there.
What Proper Youth Strength Training Looks Like
Not all strength training is created equal. The difference between a safe, effective youth program and a risky one comes down to how it’s structured and who’s leading it. Here is what proper youth strength training should include:

How We Approach It at Take5 Athletics
At Take5 Athletics, every athlete starts with a Functional Movement Screen (FMS) evaluation. This gives us a baseline understanding of how your child moves: where they are strong, where they have limitations, and where there may be asymmetries or compensations that could lead to injury down the road.
From there, we build phase-based programming that progresses your athlete through structured training blocks. We test every six weeks to track measurable improvements and adjust the plan based on real data, not guesswork.
Our training is done in small groups of 3 to 10 athletes so every athlete gets the coaching attention they need, or in 1-on-1 sessions for athletes who want fully individualized programming. Either way, your child is never just another body in a large group going through generic workouts.
We train youth athletes from Happy Valley, Oregon City, Portland, Damascus, and surrounding areas across the Portland metro. Our facility in Clackamas, Oregon is centrally located and easy to get to from anywhere in the region.
