What Age Should Kids Start Lifting Weights? A High School Strength Coach Explains

"Is my kid too young to lift?"

I hear this from parents almost every week. I've been coaching for over 14 years, and right now I train hundreds of high school athletes every season across football, lacrosse, volleyball, basketball, and more. I also work with 8th graders getting ready to make the jump to high school sports.

So here's my honest answer, from someone who's in the weight room with young athletes every day.

First, let's kill the biggest myth

Lifting weights does not stunt growth.

This myth has been around for decades, and it keeps a lot of kids out of the weight room when they'd benefit from being there. Major pediatric and sports medicine organizations support strength training for kids, often starting around age 7 or 8, as long as it's properly supervised and the child is mature enough to follow instructions.

Think about it this way: kids already put huge forces through their bodies every day. Sprinting, jumping, landing from a rebound, and getting tackled all load the body far more than a well-coached goblet squat.

What actually causes injuries

In my experience, kids don't get hurt because they're young. They get hurt because of:

• Bad form that nobody corrects
• Too much weight, too soon, usually to keep up with friends or impress someone
• No supervision, like a kid copying a workout from social media in their garage

The weights aren't the problem. The coaching is.

So what's the right age?

The better question isn't "how old?" It's "are they ready to be coached?"

A kid is usually ready when they can:

• Listen to and follow instructions
• Focus for a full session without horseplay
• Accept being told to use a lighter weight
• Understand that form comes before load

Some 11-year-olds are ready. Some 15-year-olds aren't. Maturity matters more than the number on the birth certificate.

How I train young athletes

When I work with middle schoolers, the goal isn't to make them as strong as possible as fast as possible. It's to build a foundation they'll use for the rest of their athletic career.

1. Movement first. We start with bodyweight: squatting, hinging, pushing, pulling, jumping, and landing correctly.
2. Technique before load. Weight only goes up when every rep looks the same as the first one.
3. Slow, smart progression. Small jumps, week after week. No ego lifting.
4. Coaching on every rep. Kids never just "go lift." Someone is always watching and correcting.

Why 8th grade is the sweet spot

Here's what I see every year: freshmen who already know how to squat, hinge, and land correctly are ahead from day one.

They're more confident in the weight room. They pick up new lifts faster. They get hurt less. And when high school training ramps up, they're ready for it instead of spending their first season learning the basics.

The kids who start from zero as freshmen aren't doomed, but they're playing catch-up. If your athlete is in 7th or 8th grade and wants to compete in high school, now is the time to build that foundation.

The bottom line

• Lifting doesn't stunt growth.
• Kids can start strength training when they're mature enough to be coached, often around 7 or 8.
• Bad coaching is the real risk, not age.
• 7th and 8th grade is the ideal time to get ready for high school sports.

If you're a parent with an athlete in this age range and you have questions, reach out. I'm always happy to talk about where your kid is and what they need.
