Why High School Football Players Should Avoid One-Rep Max (1RM) Lifts in the Weight Room

In high school weight rooms across the country, it’s common to see coaches hyping up “max-out days” where athletes attempt their one-repetition maximum (1RM) on bench press, squat, or deadlift. The atmosphere is electric—teammates cheering, records posted on the board, and a sense of accomplishment for those who hit big numbers. But beneath the excitement lies a serious question: Is this practice worth the risk for developing teenage athletes, especially football players whose primary goal is on-field performance, not powerlifting glory?

The short answer is no. For high school football players—typically aged 14–18, with bodies still undergoing rapid growth and maturation—regularly testing or training with true 1RM lifts carries far more risk than reward. Submaximal training, such as working in the 3–5 rep range (roughly 85–95% of 1RM), delivers superior long-term strength gains, better technique reinforcement, and dramatically lower injury risk.

The Risk-Reward Imbalance of 1RM Lifts

The “reward” of 1RM testing is often overstated. It provides a single data point of maximal strength and can create short-term motivation or competition. However, these benefits are minimal and short-lived:

• The number becomes outdated within weeks as the athlete progresses.

• It has limited direct carryover to football, where repeated explosive efforts, power endurance, and change-of-direction ability dominate—not a single all-out rep.

• Accurate programming loads can easily be calculated without ever touching a true max, using rep-max estimators, velocity-based training, or perceived exertion.

The risks are substantial, especially for adolescents:

• Technique Breakdown Under Extreme Load: Near or at 100% of capacity, even experienced lifters experience form degradation. In less experienced high school athletes, this commonly manifests as valgus knee collapse, excessive lumbar flexion/extension, loss of neutral spine, or shoulder protraction issues—greatly increasing shear and compressive forces on joints and soft tissues.

• Acute Injury Potential: Failed or barely completed max attempts place enormous stress on tendons, ligaments, and joints. Common outcomes include muscle strains, tendon irritations, joint sprains, and in rare cases more serious spinal or growth-plate issues when form completely fails.

• Central Nervous System Fatigue: True maximal lifts are neurologically taxing. Frequent or poorly timed max efforts lead to accumulated fatigue that impairs recovery, reduces performance in sport practice, and paradoxically increases injury risk on the field (where most football injuries occur).

Football requires strength that can be displayed play after play—often 50–80 high-intensity efforts in a game—not one grinding rep in the weight room.

The Developing Adolescent Body: Why Teens Aren’t Mini-Adults

Athletes aged 14–18 are in the midst of rapid physiological changes:

• Growth spurts cause bones to lengthen faster than muscles and tendons can adapt, temporarily reducing tissue resilience around joints.

• Hormonal fluctuations (testosterone, growth hormone, etc.) drive huge potential for adaptation but also create windows of relative weakness.

• Neuromuscular coordination and motor unit recruitment patterns are still maturing—teenagers rely more on brute effort than efficient mechanics, making technical breakdown under extreme loads far more likely.

• Growth plates remain open in many athletes until late adolescence, and while properly supervised lifting does not stunt growth, excessive uncontrolled loading during failed maxes can theoretically cause irritation.

These factors combine to make the adolescent athlete more vulnerable to overload injuries than a fully matured college or professional player.

Why Submaximal Lifts (3–5 Reps) Are Superior for Football Players

Training with heavy loads in the 3–5 rep range (85–93% of 1RM) consistently produces better long-term results for strength, size, power, and—most importantly—durability.

Reliable 1RM estimation from any heavy set

Key advantages of 3–5 rep training:

• More high-quality repetitions reinforce perfect movement patterns under heavy load.

• The added volume in this intensity zone drives muscle hypertrophy (adding protective mass) while still developing maximal strength.

• Bar speed can be maintained, enhancing rate of force development—critical for explosive football movements.

• Recovery between sessions is faster, allowing higher weekly training frequency and volume.

• Estimated 1RM can be calculated accurately from any 3–5 rep performance using widely accepted formulas (Epley, Brzycki, etc.), eliminating the need to ever test a true single.

Many of the most successful high school and college programs have abandoned routine 1RM testing entirely, replacing it with AMRAP (as many reps as possible) tests at 85–90%, velocity stop points, or simply tracking load/rep increases over time.

Bottom Line: Build Stronger, Safer Football Players

Prioritize long-term athletic development and on-field dominance over weight-room bragging rights. Train heavy, train often, and train with impeccable technique—but leave true one-rep maxes to competitive powerlifters. Heavy triples and fives, done consistently and progressively, will produce bigger, stronger, more explosive athletes who stay healthy through a long season.

Strength is proven on the field, not on a single rep under the bar. Train smart, not max.
