Neck Training for Youth Athletes
The population where the concussion evidence is strongest, the injury tolerance is lowest, and the margin for getting it wrong is smallest.
The strongest evidence linking neck strength to lower concussion odds comes from high school athletes — 6,704 of them, with 5% lower odds per additional pound of neck strength. So the population the evidence best applies to is exactly the population most parents are asking about. Youth neck training is appropriate from roughly the age a child is ready for organised sport, provided it is supervised, starts genuinely light, and progresses slowly: a young cervical spine tolerates substantially less force than an adult’s. Use a head harness with the smallest load increments you can find, train two to three times a week, and never let load rise faster than technique.
The evidence applies to this group specifically
Most sports-science findings are generated on adults and extrapolated down to children with a shrug. Neck training is the unusual case where the reverse is true.
The single best study linking neck strength to concussion risk was run on high school athletes. 6,704 of them, across 51 schools in 25 states, in boys’ and girls’ soccer, basketball and lacrosse. Certified athletic trainers measured neck strength before the season and counted concussions during it.
After adjusting for gender and sport, overall neck strength remained a significant predictor of concussion (p = 0.004). For every one pound increase in neck strength, odds of concussion decreased by 5 % (OR = 0.95, 95 % CI 0.92-0.98).

A 2019 Rutgers review in the Journal of Orthopaedic and Sports Physical Therapy looked across the literature and recommended cervical spine assessment at pre-participation physicals and neck-strengthening work in pre-season training — and specifically flagged that female athletes, who typically have less neck strength, experience higher concussion rates, more severe symptoms and longer recovery.

That finding cuts against how youth sport actually behaves. Neck work, where it happens at all, happens in boys’ football and boys’ wrestling. On the evidence, the athletes with the most to gain are girls playing soccer and lacrosse, and almost nobody is training them.
What is still not claimed here: nobody has run the trial that trains one group of young athletes, leaves another untrained, and counts concussions. Neck training does not make a child concussion-proof, and any company that tells you otherwise is selling you something the evidence does not support. Full treatment: neck strength and concussion risk.
Why a young neck needs more caution, not less
The reason to be careful is not that resistance training is dangerous for children. It is that a young cervical spine tolerates less force, and the gap is larger than most people assume.
Crash-injury standards define tolerance limits for different-sized occupants. The tension intercept used in the Nij neck injury criterion is 2,800 N for a six-year-old, against 4,500 N for a mid-size adult male and 5,440 N for a large male.
A six-year-old’s neck tolerates roughly 60% of the adult male value — while a child’s head is proportionally larger and heavier relative to their body than an adult’s. Smaller structure, bigger lever, less tolerance. See cervical injury tolerance.
None of that is an argument against training. It is an argument for starting lighter and progressing slower than you would with an adult, and for using equipment where the load is a known number rather than a guess.
What the youth strength-training consensus says
Resistance training for children is one of the better-settled questions in sports science, and the answer has been the same for two decades.
The National Strength and Conditioning Association’s position statement concludes that “a properly designed and supervised resistance training program is relatively safe for youth,” that it enhances strength and power, and that it “can increase a young athlete’s resistance to sports-related injuries.”
On readiness: “If a child is ready for participation in sport activities (generally age 7 or 8 years), then he or she is ready for some type of resistance training.”
On method: youth must “first learn how to perform each exercise correctly with a light load” before intensity advances. And the hard limit — “If qualified supervision, age-appropriate equipment, and safe environment are not available, youth should not perform resistance exercise.”

Every one of those conditions applies to the neck with more force than it applies to a squat, because the tissue being loaded sits directly beneath the skull.
How to actually start
Get a head harness with small increments. This is the practical crux for a young athlete. The best-evidenced adult progression in the literature advanced half a kilogram at a time; a child needs to advance in steps at least that small, and preferably smaller. That is achievable with a harness and a set of light plates. It is not achievable by pressing against a hand, where “a bit harder than last week” is the only available increment, and it is not achievable on a gym machine whose lightest plate is 5 kg.
Two sessions a week to begin with, three at most. Neck soreness disrupts sleep, and sleep matters more for an adolescent than the extra session does.
Two sets of ten, at a load they could clearly do five more with. If the last repetition is a struggle, it is too heavy. Youth training should never approach failure.
Slow tempo, no momentum. Two to three seconds out, brief pause, two to three seconds back. Every controlled protocol in the literature uses controlled tempo and none uses ballistic movement.
Neutral head position. Joint reaction forces rise steeply past roughly 15° of flexion, 30° of extension, and 35° of rotation. Young athletes work in the middle of the range, always.
An adult watches every session for the first month. Not because the exercise is dangerous, but because form drifts and nobody notices their own neck position.
Skip bridging entirely unless the child wrestles, in which case it is a competitive skill they will learn under a coach anyway. The wrestler’s bridge puts a large, non-adjustable load through the cervical spine in extension, and “non-adjustable” is the disqualifying word for a growing athlete. See bridging.
Stop signals a parent should know
Stop the session and get it assessed for any of these:
- Numbness or tingling in the arms or hands
- Weakness in a limb
- Pain radiating below the shoulder
- Dizziness, visual disturbance, or difficulty swallowing
- Headache brought on by the training itself
Those are neural symptoms, not muscular ones, and they are not something to train through. The full list, including the conditions that require medical clearance before any loaded neck work, is on safety and contraindications.
Muscular soreness in the days after a session is normal and expected. Anything that travels down an arm is not.
What to buy
A head harness and the lightest plates you can source. That combination costs less than a single season’s registration fee in most sports, lives in a gym bag, and progresses in increments small enough for a twelve-year-old.
Neck Flex® is the harness this site’s publisher makes, and it is also the only neck harness named by brand in a peer-reviewed randomised controlled trial — a twenty-week study on Royal Danish Air Force aircrew lists its equipment as “The Original Neck Flex® Head Harness, Gonzo Companies, USA.” That is a record of equipment selection by researchers with no commercial interest, not proof it outperforms a competitor in a comparison nobody has run. Both halves are true. See what to buy and why and the ownership disclosure.
Setup matters more for a young athlete than for anyone else, because a harness that slides is a harness they will brace their jaw against. Watch a setup video together before the first session.
The four sentences to give a worried parent
Stronger necks are associated with fewer concussions. 6,704 high school athletes, 5% lower odds per pound, adjusted for sex and sport.
Neck training reliably makes necks stronger. High-quality evidence, large effect, not in dispute.
Nobody has run the trial connecting those two directly, so nothing here is a guarantee, and no product prevents concussion.
Not training is not neutral. Untrained control groups in the published studies measurably lost cervical strength across a season. The choice is not between training and staying the same.
That case survives being read carefully, which is the only kind worth making about a child.
