We were told a big squat equals a big hitter. It sounds logical. It feels right. But it is a lie. Weight room numbers tell me how a kid moves a stationary iron bar. They tell me nothing about how he handles a 240-pound linebacker moving at full speed.
The 90-Second Teaching
Every fall, a coach watches his strongest kid get pushed around. The kid who owns the weight room gets washed out of the hole on the first snap. That is the Contact Gap: the weight room built an engine, but nobody built the chassis to survive the impact. Moving a stationary bar and moving a resisting man are two different skills. Only one of them shows up on Friday night.
Contact Prep is how you train the second skill. Physicality is not a personality trait a kid is born with. It is coached, graded, and made repeatable under pressure — the same way you coach a clean or a forty. You start with the smallest possible impact, on the floor, without a partner, and you climb. Grounded, then Combatives, then Partner Work. Ten minutes a day. A floor and a partner. No pads.
You do it in the off-season because the alternative is asking a kid to learn the most violent part of the game in August, when the stakes are highest and the margin for error is zero. That is how kids get hurt. Bags do not fight back. If your contact reps never fight back, neither will your kids.
1.The Case — Violence Is a Skill
For decades the sport ran on a lie: a big squat equals a big hitter, a 300-pound bench means a kid can control the line of scrimmage. It sounds logical. It is false. Weight room numbers are vanity metrics. They measure how well an athlete moves a stationary iron bar. They say nothing about how he strikes, stabilizes a shoulder in a collision, or moves a man who does not want to be moved.
Weight room as proxy
- Belief
- Get strong on the bar and physicality takes care of itself.
- What it builds
- A kid who tests well and gets pancaked. The "weight room warrior."
- The failure
- Strength that never transfers because contact was never trained.
Contact as a trained skill
- Belief
- Physicality is a skill. It is taught, developed, and made repeatable.
- What it builds
- A kid who can strike, brace, and fall correctly before pads go on.
- The win
- Injury rates drop. Physicality shows up on the field, not just the platform.
"You can push the sled all day and get a good leg burn, but the sled — once you get that thing rolling, it rolls. That is not as sore-inducing as somebody who does not want to be moved and is resisting and twisting and torquing." — Leech
That is the whole argument in one image. A sled yields. A bag falls down and never fights back. If a player's only contact reps come against equipment that offers no resistance, he has never trained the thing a game actually demands. Contact Prep replaces the yielding object with a live, resisting partner — safely, and in graded steps.
2.The Science — Why It Works
This is the part that wins the argument with the skeptic in your building. Contact Prep is not a philosophy dressed up as drills. It sits on top of three well-understood mechanisms: two kinds of muscle damage, the physics of force absorption, and the workload spike that actually gets kids hurt.
Two kinds of muscle damage
Andy Ryland at USA Football teaches the distinction that anchors the whole method. When a player returns to contact, he is hit by two separate stressors. You have to train against both, and neither one lives in a barbell.
The damage from taking the hit
- Source
- The running back getting tackled. The lineman colliding. The receiver landing after a catch.
- Barbell trains it?
- No. A squat never delivers a collision.
- How you train it
- Expose the body to small impacts first, then raise intensity and frequency over the off-season.
The damage from delivering it
- Source
- The strain of blocking, of moving a man who does not want to move. Why linemen are sore after standing "around."
- Barbell trains it?
- No. The strain of a resisting body is different from the bench or the squat.
- How you train it
- Live partner work, graded up little by little as camp approaches.
Both fade with exposure. The first time a kid wears a helmet, his neck is sore — the weight is unaccustomed. Train the neck and introduce the load early and that soreness drops. Same logic for the whole body: raise impact volume and intensity slowly across the off-season and the athlete arrives at camp less sore and more durable. You will never fully replicate a live tackle in April, but you can start light and climb so the first collision of August is not the first collision of the year.
Force breaks you — and keeps you from breaking
The physics is the impulse-momentum relationship. Impulse is force applied over time. A collision compresses a large momentum change into a tiny window, which means enormous force. You cannot slow a football collision down — an athlete who decelerates gently to reduce force is a step late and a non-factor. So the answer is not less force. It is a body that can produce and tolerate more of it.
Force is what breaks our athletes, and force is what prevents them from being broken. A stronger athlete who has trained his tissues to tolerate high impulses is far less likely to be broken by a collision than a weaker one.
Extensive to intensive
- Principle
- Expose tendons and muscles to slowly greater forces so they structurally adapt to absorb rapid impact.
- Tools
- Heavy strength work plus progressively intense plyometrics (up to depth-drop landings).
- Contact Prep role
- Plate drops and grounded work are the entry rungs of the same ladder — force absorption you can run without a platform.
Isometric strength at contact
- Principle
- The instant two players collide, the demand becomes a near-maximal isometric hold to keep position.
- The tell
- Ever had the wind knocked out of you? It happened when you were not braced. A prepared athlete tenses the core and absorbs it.
- Contact Prep role
- Combatives train the hold-your-ground skill the barbell can't: strength in leverage positions, single-arm, extended.
The spike is what actually gets kids hurt
Here is the part most programs miss. The biggest injury driver at the return to contact is not a lack of off-season hitting on its own — it is a sudden, unmanaged spike in total workload. The "hell week" camp that jumps from a quiet summer to full-speed blocking and tackling overnight is a workload cliff, and cliffs hurt people.
| Research finding | What it means for Contact Prep |
|---|---|
| Rugby league players who completed more uninterrupted preseason sessions had lower in-season injury rates (Windt et al.). | Consistent graded contact exposure across the off-season buys availability in the season that matters. |
| Weekly training-load increases should not exceed ~10% over the prior week (Drew & Finch). | Ramp contact volume in small steps. Do not double a kid's collisions week to week. |
| Sprinting, blocking and tackling are major systemic stresses drawn from one stress pool. | When live contact returns, cut weight-room volume — especially lower body — or you overflow the cup and guarantee breakdown. |
3.The Three-Phase System
The whole course is a logical progression from the floor to full chaos. Each phase adds unpredictability and gets closer to the game. It is not a plug-and-play template. It is a playbook — you fit the concepts into the schedule you already run.
| Phase | Goal | What it looks like | Partner? |
|---|---|---|---|
| 1 · Grounded | Build the chassis. Shoulder girdle, core, force absorption. | Crawls, rolls, plate drops, bear holds — on the floor, low impact. | No / light |
| 2 · Combatives | Move a body. Manipulate an opponent's center of gravity. | Hand fighting, striking, leverage battles, position holds on the feet. | Yes, controlled |
| 3 · Partner Work | Apply it live. Mirror the chaos of a real play. | High-speed, competitive 1v1 drills at game-like intensity. | Yes, live |
Phase 1 · Grounded — build the foundation
Everything starts on the floor, where the impact is smallest and the closed-chain relationship between hand, shoulder, and ground can be rebuilt. This is where you re-establish the shoulder's ability to accept and transfer force before any standing contact returns.
Why floor first: the shoulder girdle has to be rebuilt after a season of contact, and force absorption capacity resets from the ground up. Skip it and the first contact session of camp looks ugly.
Phase 2 · Combatives — move a man
On the feet now. Players learn to hand-fight, strike, and move an opponent who is resisting. This is the isometric, leverage-based strength the barbell cannot teach: holding a position under duress, winning the center of gravity, staying strong single-arm and extended.
The skill focus: setting an edge as a defender, double-team steps as a lineman — the transfer points where "functional strength" stops being a cliché and starts being a rep.
Phase 3 · Partner Work — live application
The final layer. High-speed, high-intensity, competitive drills that mirror a live play. This is where confidence is forged — a kid who has won a hundred graded 1v1 battles in the off-season is not meeting live contact for the first time in August.
The by-product: these drills are conditioning and they are fun. Coaches who run them report better off-season attendance, because kids would rather compete than run another gasser.
4.Block Zero — The Post-Season Re-Entry
Most periodization frameworks start at Block One, the off-season build. Block Zero sits before it — the four-week window after the last game and before the off-season build kicks in. It is the layer most programs skip, and the one that decides whether players survive August. It is also the exact install a coach can run the Monday after a playoff loss.
Block Zero is Phase 1 of Contact Prep. You do not jump back into wrestling drills and push-pull contact after the season. You re-establish the shoulder girdle and its ability to accept impact. Start at zero. Progress from lowest impact to highest.
Bear crawl progressions — the lowest entry point
Hands under shoulders, knees under the belly button, knees one to two inches off the floor, tight crunch position the whole time. Forward, backward, then lateral (opposite arm, opposite leg). Use a whistle — every blow is one step, which forces time in position. Progress two-arm → single-arm (more shoulder-girdle demand) → bear switches (faster, more impact). AC-joint sprains from the season sit out the single-arm work at first.
Plate drops — reintroducing force absorption
Partner drops a plate; the athlete catches it on the sides — where the numbers are — not from underneath. Phase 1 is a straight-arm catch. Then add a rotational component so the obliques and the rotational sling get involved. This is depth-drop force absorption you can run without a platform. It re-teaches the shoulder to accept and transfer impact.
Rolling patterns — how to fall without getting hurt
Teach the athlete to roll over the soft tissue of the shoulder blade, chin tucked — not to reach for the ground with an outstretched hand. That reach reflex is exactly how kids tear a labrum (SLAP) or sprain an AC joint. Rolling mechanics transfer directly to game falls.
Bear holds with load — own the closed-chain position
Static bear hold, then layer plate slides, banded overhead press, and banded rows to build time in the closed-chain position and re-establish the hand/shoulder/ground relationship under a little load.
5.Neck & Force Absorption — Protect the Brain
Elite programs treat neck training as non-negotiable for collision athletes, and the reason is blunt: the neck stabilizes the cervical spine, manages the weight of the helmet, and helps protect the brain. The published literature points the same direction — Collins and colleagues found that for every one pound of increased neck strength, the odds of concussion dropped about five percent. Train the neck.
Neck programming — the non-negotiable dose
The neck is a stabilizer built for endurance, so it wants frequency and reps over max load. Train it off-season and in-season both. A clean in-season model runs three-week waves of manual-resisted neck: 2×15, then 2×12, then 2×10. It stays progressive; it never gets dropped.
Partner-resisted neck
- 6-way neck
- Partner applies resistance in all directions: flexion, extension, both lateral flexions, both rotations.
- Iso-holds & battles
- Partner applies continuous isometric pressure the athlete braces against — the exact static bracing a collision demands.
- Deep neck flexors
- Prone, chin tucked, forehead toward the floor, glutes on, 4-second holds; progress with side-bend and rotation.
Neck supports & leans
- Standing neck support
- Trap the ball between wall and back of the head, chin tucked, head aligned. Iso holds of 6-8 seconds.
- Neural drive bonus
- Superset the neck support with a lower-trap raise — activating the neck extensors potentiates the next lift.
- Bridges (advanced)
- Forward, backward, wrestling bridge — high compressive load; progress carefully by training age.
6.The 10-Minute Install — Where It Fits
Contact Prep does not need its own hour. It slots into the off-season day you already run. Ten minutes. The one rule: it does not super-set into lifting — no bench-press-and-plate-drop combos.
| Slot | What goes there | Why |
|---|---|---|
| Warmup — the return trip | Bear crawl variations coming back from dynamic stretches ("knee-hug spider out, lateral bear crawl back"). | Free reps in a slot that is usually wasted movement. |
| Athletic development block | Pair a jump, a med-ball throw, and a crawl/roll. Or place grounded work between speed and the weight room. | Primes force absorption without draining the CNS before lifting. |
| Conditioning | Competitive Phase 2-3 partner battles instead of another gasser. | Conditioning that is fun, competitive, and builds physicality. Attendance goes up. |
"I've talked to plenty of coaches who started incorporating these things and they get more and more kids to come out for summer training, because it's fun. If you're a coach struggling with attendance, some of this is fun enough that kids will want to come in and do it." — Leech
Bridging the gap — the seasonal case
Season ends around Thanksgiving. Pads do not come back until August. For a kid who plays a winter sport, then a spring sport, then disappears for half the summer, that is the better part of a year with no contact. Spring ball ends in April and the same gap opens before camp. You cannot take three months off from physicality and expect a kid to look great in preseason. Contact Prep is what keeps the skill alive across the dead months — and it works for programs with limited equipment or limited coaching access, because it needs neither.
7.Safety & Progression — What It Is NOT
The most common hesitation is that this turns into kids roughhousing until somebody gets hurt. It does not — if you follow the progression. Three guardrails define what Contact Prep is not.
- It is not a free-for-all. You start with beginner drills, and you start without partners. You progress an exercise only when the drill and the athletes' maturity are both ready. Let it get loose and sloppy and somebody gets hurt. Follow the ladder and they do not.
- It is not wrestling practice. Wrestling is great, but three hours of spin-to-win that kids hate is not the goal. Contact Prep is graded, purposeful, and short. If your winter sport does the job and kids love it, great. If not, this is the off-season substitute.
- It is not football practice. One coach cannot teach the technical nuance of every position at once. Part of this is deliberately generalized — the point is to get one-on-one, close-space, physical contact reps in, not to coach hand placement rep by rep.
8.The Data — Physicality Is a Math Equation
The "violence is a skill" argument is not only philosophical. Four independent data sources back it with numbers. Coaches respect numbers. Use them.
1 · 81% of NFL fumbles are manufactured
From the 2019 LA Rams "Fumbles Are Man Made" study of 456 NFL fumbles: 62% came from conscious effort (trained strip technique — Run-Run-Reach, Rake, Peanut, Hammer, Punch), 19% from raw violence of the collision, and only 19% from bad ball security.
Conscious effort + violence = 81%. If four of five fumbles at the highest level are manufactured by trained, deliberate physical technique — not luck — then failing to train your ball carriers against those techniques is malpractice.
Marketing line: "81% of fumbles in the NFL are manufactured by trained defenders. Are your ball carriers trained to handle it?"
2 & 3 · Hit Score and Truck Stick — the physics of a collision
Two independent sources landed on the same formula. Hit Score = Speed × Body Weight (@scottkuehn88). Truck Stick = Weight × Velocity (@HuthStrength). That is just momentum — p = mv — applied to who wins a collision.
The takeaway: physicality is mass in motion, not size alone. A lighter, faster player can out-physical a heavier, slower one. All three inputs — mass, velocity, and the skill to deploy them at contact — are trainable. None are inherited. Max squat and max bench do not appear anywhere in the formula.
4 · A single negative play cuts scoring probability in half
SportSource Analytics, across multiple conferences: a drive with no negative play scored a touchdown roughly 34-43% of the time. One negative play dropped that to 10-18%. A sack dropped it to single digits in most conferences.
Negative plays are manufactured by the defense — which means they are trainable. Contact Prep trains the defender to make them and the lineman to survive them. "A single negative play cuts your chance of scoring in half. What are you doing to prevent them — and create them?"
9.Coach Objections — Honest Answers
"Is this safe for high school kids?"
It is safer than sending them into a game without it. You are teaching them to handle impact correctly — to fall without reaching, to brace before contact, to stop using the head as a weapon — before the pads and the game speed raise the stakes. The progression starts without partners and only advances when the drill and the athlete's maturity are ready.
"Do I need special equipment?"
No. A floor and a partner. A 25-pound plate for plate drops and a Swiss ball for neck work if you have them, but the core system runs on bodies and the ground. That is the point — it is built for the program with no budget and no five-man sled.
"Does this take too much time?"
Ten minutes. It slots into the warmup return trip, the athletic development block, or your conditioning period. If you cannot find ten minutes to make sure your players are safe and physical, you have bigger problems than this course.
"I already have a lift program. Why do I need this?"
Because your lift program does not teach a kid how to strike, how to stabilize a shoulder in a collision, or how to move a man who is resisting. Those are separate skills with separate muscle-damage profiles. The barbell builds the engine. Contact Prep builds the chassis that lets the engine survive the impact.
"Won't my winter sport (wrestling) cover this?"
Sometimes. If your kids wrestle, love it, and get real reps, that is one thing. But a wrestling practice that is three hours of spin-to-win the kids do not enjoy is not automatically better than ten focused minutes of graded contact prep. And a kid who plays basketball, or nothing, gets none of it. Contact Prep is the off-season floor that does not depend on a second sport.
"How do I know the ramp is right so I don't hurt someone?"
Two anchors from the load-management research. Keep week-to-week contact-volume increases small — roughly 10% — rather than doubling a kid's collisions overnight. And when live team contact starts in camp, pull weight-room volume, especially lower body, because practice is a major systemic stress drawing from the same pool. The goal is a slope, not the "hell week" cliff that actually gets kids hurt.
Glossary
- Violence is a skill
- The core teaching: physicality is trained, coached, and repeatable — not an innate trait. The counter to "a big squat equals a big hitter."
- The Contact Gap
- The distance between weight-room strength and on-field physicality. A strong kid who gets pancaked has an engine but no chassis.
- Impact-induced muscle damage
- Damage from taking a hit — the tackled back, the colliding lineman. Trained by graded exposure to impact, not by lifting.
- Exercise-induced muscle damage
- Damage from delivering force — the strain of moving a resisting man. Why linemen are sore after "standing around." Trained by live partner work.
- Impulse-momentum relationship
- Force applied over time. A collision compresses a large momentum change into a tiny window, producing enormous force. You cannot slow it down, so you build a body that tolerates it.
- Creatine kinase (CK)
- Enzyme released when muscle is damaged; the standard biochemical marker. Spikes with unaccustomed preseason load, then settles as the body adapts.
- Extensive to intensive
- Tissue-hardening principle: expose tendons and muscles to slowly greater forces so they structurally adapt to absorb rapid impact.
- Block Zero
- The four-week post-season re-entry window before the off-season build. Phase 1 of Contact Prep — the layer most programs skip.
- Three phases
- Grounded (floor, force absorption) → Combatives (move a man, on the feet) → Partner Work (live, competitive, game-like).
- Hit Score / Truck Stick
- Speed × Body Weight (or Weight × Velocity) = who wins the collision. Momentum physics, from two independent sources.
