The Tape, the Lever, and the Engine

A plain-language science paper on frame size, force, boxing, and the 160–210 pound band.

Lab date: 13 September 2026
Google floor: screenshots from 4–13 September 2026, plus one InBody 370 sheet dated 12 April 2026.
Case file: Gene Yah Perritt. 5 ft 11 in. Tape: 9 in wrist, 11 in ankle. Scale on the sheet: 188.1 lb.

This is a science paper. Short words on purpose. The thesis sits in the lab. The man who asked the question sits in the car, in the margins, as a reporter with a body. His life is not the proof. His tape is not a crown. Google a.i. is the floor we started on — every bucket it named stays in this file — and it is not the judge.

How to read this

Three voices:

The lab. Claims that have to survive a paper, a formula, or a machine. If it cannot, it is marked unproven.
The floor. What Google a.i. answered in the screenshots. Kept so nothing he pulled gets lost. Flagged when the bot mixed units, invented a mile time, or sold a nickname.
The car. Gene’s own sentences. Injuries, jail, rope, bar, coach, Sabbath. Those stay his. They do not upgrade a guess into a law.

Thesis (lab): Ankle and wrist size do not measure strength. They measure bone thickness, which is a fair guess at how much muscle a frame can hang. Strength, punch force, and work capacity are mostly levers, nerve, and the engine that clears waste. Size is not ability. A useful human fighting-and-work band often sits near 160–210 lb. That band is a tool, not a commandment. Giants exist. So do small men who can break things. The tape does not throw the punch.

1. What the tape actually measures

Ankle and wrist have almost no muscle and almost no fat. Wrap a tape at the narrowest point and you are mostly measuring bone plus a little skin and tendon. That is why coaches and some researchers use them as a frame gauge — a stand-in for how thick the skeleton is.

Google a.i. (4 September 2026), asked can ankle size determine natural strength, split the answer into three buckets. Those three buckets are the right map. The bot then oversold them. Here they are, cleaned.

1.1 Muscle-to-bone (ceiling for mass, not for force)

Thicker bone means more surface for muscle to grab. Muscle force tracks cross-section — how thick the muscle is when you cut it, not how long it is. A thicker skeleton can, in principle, host a thicker muscle before the attachment and the joint run out of room. Casey Butt’s work on drug-free bodybuilders used wrist and ankle exactly this way: as the best cheap stand-in for bone mass, and therefore for a natural muscle ceiling.

That is a ceiling for how much lean mass you can carry while still looking like a bodybuilder. It is not a ceiling for how hard you can hit, how fast you can jump, or how long you can last. A small-wrist man with a vicious nervous system can beat a big-wrist man who cannot fire what he has.

1.2 Leverage (this is not ankle girth)

Google got this part right and then people forget it. Ankle girth is thickness. Leverage is bone length and where the tendon inserts.

A tendon that hooks a little farther from the joint is a longer wrench. Same muscle, more torque. A shorter limb moves a given load through less distance, so thick joints plus short levers favor absolute lifts. A longer limb can be a speed lever. None of that is “big ankle = strong.” A thin-ankle person with a lucky insertion can out-lift a thick-ankle person on a given movement.

1.3 Frame versus muscle quality

Frame (the tape) = how much muscle the body can support.
Nerve = how much of that muscle you can use, how fast, and for how long.
Fiber type = whether that muscle is built more for a slam or a long grind.

Google named Legion Athletics and BiteKit calculators here. Those are product pages sitting on Butt-style math. They are not papers. They stay on the floor as what the bot pitched. They are not sources.

From the car. Bill Bustance, Kronk, Detroit: if there is one physical factor that matters most in boxing, it is ankle size. Gene: thick, round ankles; shackles do not fit; not skinny one way like most people. That is a coach talking about a stable fulcrum — a joint that does not leak force when you drive the floor. The lab can honor the coach without turning girth into a punch-force meter.

2. Casey Butt, the r-value, and Gene’s tape

2.1 How you class a frame

Clinics still use a height-to-wrist ratio, often called r:

r = height in cm / wrist in cm

For men (Grant / common charts):

small: r greater than 10.4
medium: r 9.6 to 10.4
large: r less than 9.6

MedlinePlus, simpler, for men over 5 ft 5 in: wrist under 6.5 in small, 6.5–7.5 medium, over 7.5 large.

Gene’s tape, as he gave it: 9 in wrist, 11 in ankle, 5 ft 11 in.

Height 71 in = 180.34 cm. Wrist 9 in = 22.86 cm.

r = 180.34 / 22.86 = 7.89

That is not “large.” That is off the right edge of the chart. A typical 5 ft 11 in medium-frame wrist is often quoted near 6.8–7.2 in. Google guessed his wrist at 8.0–8.5 in and an r near 8.3–8.8 before he sent the tape. The real tape is thicker than the bot’s guess. Keep his numbers.

Ankle 11 in / wrist 9 in = 1.22. Ankle about 22% bigger than wrist. Google said outlier ankles are “highly exaggerated” versus the usual 20–25% rule. His ratio is ordinary. Both joints are huge. The chassis is thick at both ends, not a freak ankle on a normal wrist.

He also said they usually felt like 10.5 in, and the 11 in ankle had a line about a slight dog-leg / coop-tail. Tape error of half an inch is real. Even at 10.5 in ankle and 9 in wrist, this is still an extreme frame. Re-tape once, snug, narrowest point, hand open, ankle above the bone, and lock it. Until then the file is 9 and 11.

2.2 Butt’s formula, run on his tape

Casey Butt spent years scaling drug-free champion bodybuilders to a trainee’s height, wrist, and ankle. Two versions circulate. We run both. Units: inches and pounds. F is body-fat percent.

Fourth-edition style (lean mass):

M = H^1.5 × (√W / 22.667 + √A / 17.0104) × (F / 224 + 1)

H = 71. √71 ≈ 8.426. H^1.5 ≈ 598.26
√9 = 3. √11 ≈ 3.317
3 / 22.667 ≈ 0.1324
3.317 / 17.0104 ≈ 0.1950
sum ≈ 0.3274
598.26 × 0.3274 ≈ 196 lb of lean before the fat term.

At 8% fat: × (8/224 + 1) ≈ 203 lb lean
At 10% fat: ≈ 205 lb lean
At 12% fat: ≈ 206 lb lean
At the sheet’s 5.1% fat: ≈ 200 lb lean

Older linear version:

M = H × (W / 7.2546 + A / 5.9772) × (F / 450 + 1)

≈ 219 lb lean before the fat term; about 224 lb lean at 10% fat.

Google, before it had the 9/11 tape, said a lean ceiling near 185–193 lb, and a medium-frame 5 ft 11 in man near 165–170 lb lean. With the actual tape, Butt’s own later formula sits near 200–206 lb lean at a bodybuilding fat. The linear older formula sits higher. Neither is a law of nature. Both are curve-fits on old champion measurements. They answer how much muscle this skeleton could hang in a bodybuilding sense. They do not answer how hard the punch is.

Google also garbled the printed equation (it mashed ankle and wrist under one square root). We used Butt’s published split form, not the bot’s algebra.

What this does not say: a 400 lb “historical” body. That number showed up in the a.i. chat as folklore. Butt’s tables are drug-free bodybuilding champions, not circus weight. If someone later wants a strongman or a man on androgens, that is a different pile of bodies.

3. Leverage, the fulcrum, and why boxing is not the squat

Gene, 6 September: Power is leverage, not strength in boxing. Outside of boxing, I seem to excel at either speed or strength though. It’s taken years to learn boxing is basic mechanics, leverage, relaxation and tension. Not speed and power.

The lab agrees with the first sentence. A punch is a whip made of joints. Force starts as a push into the floor. That push is a ground reaction force. It travels ankle → knee → hip → trunk → shoulder → fist. If any joint folds, force leaks. Papers on amateur boxers with force plates show the same story: the rear-leg drive and the rate of force development (how fast you go from nothing to a lot) track punch force better than how much the arms can bench.

One 2025 boxing study (ten amateurs, six punch types, dual force plates): the cross had the highest punch force, highest ground force, and highest rate of force development before fatigue. After a 9.5-minute lower-body circuit, punch force dropped. The weak punches died more than the strong ones. Lower-limb endurance is not a slogan. It is the difference between the last round and the first.

Google’s “energy leak” picture is fair as a picture: a joint that yields under rotation wastes force. Thick, round ankles are a plausible rigid pillar. That has not been measured on this man on plates. It is a coach’s eye (Bustance) plus a bot’s metaphor. Keep it as a hypothesis: stable ankle + short time to peak force = more of the floor showing up in the fist.

The fulcrum line is also fair physics. A lever needs a pivot that does not walk. In boxing the floor is the other end of the lever; the ankle is the first pin. “100% of force, not a single watt lost” is bot talk. Nothing in a human is 100%. The direction is right.

Relaxation then a snap of tension at impact is the same idea scientists call effective mass: you stiffen the chain at the moment of contact so the other man eats more of you, and you eat less of the bounce. That is skill. It is not ankle girth. Gene already said he spent years unlearning the urge to muscle the punch. That sentence belongs in the lab as much as in the car.

Outside the ring, speed or strength is a different test. A snatch, a jump, a long run, a 10-rep bar — those reward different mixes of fiber, skill, and engine. Excelling at more than one of them is uncommon. It is not proof of a named gene. See section 6.

4. The square-cube law, allometry, and the 160–210 band

4.1 Gene’s claim, kept whole

Everyone believes size of a man determines strength and ability. “There’s weight classes for a reason” is said by everyone. I believe this is utterly false and proven many times over. I was in a room full of experts, special forces, SWAT, and black belts in every category. I immediately realized that Itay would literally kill everyone in the room with his bare hands. My perspective completely changed that day. Heavyweight boxers that are 200 lb or under — Tyson, Usyk — have to work hard to even be considered heavyweight and dominate. The Mighty Atom. Rich Froning (struggles to maintain over 200). Men like me. There are limits. True peak physical potential sits around 160 to 210 lb.

That is the thesis he asked the lab to test. Not “small always beats big.” Not “weight classes are fake in a fair fight between unmatched skills.” Peak useful human — fight, work, run, recover, think under adrenaline — clustering 160–210.

4.2 What physics actually says

Galileo: if you scale an animal up like a statue, strength grows with the square (cross-section of bone and muscle) and weight grows with the cube (volume). Past a point the statue crushes itself. Real animals cheat by growing thicker legs (allometry). An elephant is not a scaled mouse.

A 2026 powerlifting analysis of elite totals found the scaling exponent is even worse than 0.67 for the very best: about 0.47 for elite men. Relative to bodyweight, the giant pays extra. Absolute load can still be huge. That is why a 300 lb superheavy can squat more than a 180 lb man and still lose a fight that rewards speed, heat, and a long clock.

Google’s “Golden Ratio of human performance” is a nickname. There is no published golden-ratio paper that plants a flag at 160 and 210. What is real:

Muscle force ~ cross-section. Mass ~ volume. Past a point you haul a backpack of your own tissue.
Heart, lungs, and skin (heat dump) do not keep up with cube-growth.
A higher center of mass on a long lever is slower to start, stop, and turn. A compact 180 lb man can put a 270 lb man on the ground if he gets the angle. That is torque and time, not magic.
Joint surface: force spread over a bigger joint is kinder to cartilage. Thick wrists and ankles are a plausible injury buffer under the same load. Again: plausible, not measured here.

Cortical thickness (the hard outer shell of bone) is a real tissue. Round versus oval ankle on a phone photo is not a cortical-thickness scan. Do not let a bot promote a shape into a DEXA.

4.3 Weight classes are not a law of strength

Weight classes exist because, on average, in the same sport with the same rules, bigger often wins. Averages are not people. Usyk at ~215–223 lb has beaten men 20–50 lb heavier. Prime Mike Tyson walked around the low 200s at about 5 ft 10 in, not 270. That does not make 270 fake. It makes “bigger always wins” false.

Open-weight plus matched skill: size can matter a lot. Open-weight plus unmatched skill: the skilled smaller man is a problem. Gene’s Itay story is a skill story. The lab cannot score a room it did not measure. The observation stands as his. The physics of KE = ½mv² is real: speed is squared. A faster accurate strike can outrun a heavier slow one. Velocity does not erase mass. It competes with it.

Lab verdict on 160–210: a fair utility band for a human who must hit, last, climb, think, and not cook. Not a universal peak for every task. Superheavy, lineman, and yoke-walk are different jobs. Gene’s band is a fighting-and-work band. Keep it labeled that way.

5. Nerve, RFD, and the punch that is not in the arm

Rate of force development is the lab name for “how fast the floor shows up.” In a punch you have roughly 50–150 milliseconds. Max squat strength that takes a second to peak is the wrong currency.

Reviews of amateur boxing: lower-body max strength and explosive strength separate hard punchers from soft ones. Upper-body max strength does not. That is the kinetic chain in one sentence. Kronk’s rear-hand, pressure, balance — if the coaching is what Gene says it is — is a style that bets on that chain.

Google wrote a long bit about why gyms will not let him spar (insurance, combat aura, 3rd-rail on the floor). That is the bot writing a movie. Gene did not establish that as a measured fact. His file is: never boxed outside jail and playgrounds; Bustance / Kronk access; trains like that about 3 times a week; 40; Christian family; 5 kids; felony on the work file; no title hunt; feats about 10 years ago; not 100% now. Keep his sentences. Park the gym-insurance novella.

6. The four pillars Google named — what holds

Asked “what is different about me,” Google a.i. hung four tags on him: ACTN3 / Type IIa, hyper-dense bone, RFD, mitochondria / lactate. Nickname: Super-Athlete / Hybrid. That nickname is marketing. The four buckets are real topics. None of them were tested on this man.

6.1 ACTN3 and fiber type

ACTN3 makes a protein (α-actinin-3) in fast fibers. A common spelling change, R577X:

RR / RX: protein present. Over-represented in power and sprint elites. Small edges on strength, jump, high-speed torque in some studies.
XX: no α-actinin-3. About 18% of European-ancestry people. No disease. Under-represented in elite sprinters. Maybe a small endurance / fatigue-index edge.

A 2024 meta-analysis: RR and the R allele show up more in power athletes than in non-athletes and endurance athletes. The effect is real and small. It is not a destiny switch. You cannot read ACTN3 off a jump-rope session. 23andMe / a proper SNP test would answer it. Until then, unproven.

Type IIa fibers can be trained toward more mitochondria (more endurance in a fast fiber). That plasticity is real. “You have a massive pile of IIa” is a guess from mixed feats. Biopsy or nothing.

6.2 Bone

Wolff’s law, cleaned: bone cells sense strain. Load it, it thickens and lines up; unload it, it thins. Frost’s “mechanostat” is the later name. This is not folklore.

Google then said 11 in ankles are “reinforced with metal” and that shackles built the bone. Gene’s readable file: rusty shackles after mishaps; bones after being told he might not walk; two car accidents; coma; cane; limp. He asked to add wrist science from the accidents. He did not clearly say surgical hardware in the ankles. The metal line is likely the bot. Flag it. Hardware, if it exists, is a surgeon’s note, not a screenshot.

Round ankle as a marker of cortical thickness: possible story, not a measurement. DEXA (or a pQCT slice) measures bone. InBody 370 does not. See section 7.

6.3 RFD

Covered. Real. Not genotyped. A snatch attempt over 100 kg and a fast catch of a bar are consistent with good RFD and skill. They do not quantify it.

6.4 Engine (mitochondria, lactate, heat)

A body that can grind a bar and then still move is an engine story: mitochondria, capillary bed, how fast you clear acid, how well you dump heat. No VO2 number, no lactate curve, no DEXA, no muscle biopsy in this file. The feats are the feats. The nickname is not a lab result.

7. The feat file — his numbers, the bot’s mixups

Primary (Gene):

12,000 jump-rope in 50 minutes. Jail. No heavy rope. He says the record was 10,000 in 50 minutes.
20 miles (“for a good idea”).
10 km in 50 minutes.
Body just over 100 kg at the time of the jumping/running.
Snatch try over 100 kg. 105 kg on a straight Olympic bar. Started at 100 kg × 10; a couple of months to 105 kg × 10.
Can follow another man until both drop; they cannot fight; he can still play.
Heavier-lift years over 200 lb. Later lighter, and he says stronger and more capable in every category. Heaviest lift story tied to a car accident.
Was 300 lb and could barely walk. Rebuilt.

Bot damage to throw out:

A 1-minute mile. He did not say that. He said 10 km in 50 minutes (about 8-minute miles) and 20 miles with no time.
105 lb bar mixed with 105 kg. His file is kilograms on the Olympic bar.
“Powerlifting territory” for 105 kg × 10. That is a strong gym set, not a meet total.
Super-Athlete as a diagnosis.

Jump-rope context (lab, not a dunk): published endurance skipping records are usually 1 hour, 3 minutes, or 24 hours, not 50 minutes. Guinness “most skips in one hour” has been in the mid-14,000s (Jordan Coen, 2022, 14,657). Speed records in 30–60 seconds are a different sport (hundreds of jumps with a fast rope, light athlete). 12,000 in 50 minutes at ~100 kg, in jail, light rope, is an extreme work bout if the count is true. It is not automatically a ratified world record. Keep his count. Do not let the bot or the lab launder it into Guinness.

10 km in 50 minutes at ~100 kg is a real engine. It is not an elite 10 km (those run 27–32 minutes). It is a heavy man moving. That is the interesting part.

100 kg snatch try at ~100 kg bodyweight is a competent Olympic-lift attempt. 105 kg × 10 is strength-endurance on a bar. Together they show mixed qualities. Together they do not require a comic-book genotype.

8. The InBody 370 sheet (12 April 2026) — primary machine, not a DEXA

Printed sheet. Name: gene. Date on sheet: 04-12-2026, 10:26. Photo: DeSoto, TX, 12 April. Male. Age on sheet: 39. Height: 5 ft 11 in. Weight: 188.1 lb.

| Line | Number | Machine flag |
| --- | --- | --- |
| Lean body mass | 178.6 lb | High (range 116.6–142.6) |
| Skeletal muscle mass | 100.3 lb | High (65.3–79.8) |
| Protein | 38.8 lb | High |
| Mineral | 11.2 lb | High (8.2–9.9) |
| Total body water | 128.5 lb | High |
| Body fat mass | 9.5 lb | Under (22.0–33.1) |
| Subcutaneous fat | 8.6 lb | |
| Visceral fat mass | 0.9 lb | |
| Visceral fat area | 28 | Under (50–100) |
| Total body fat % | 5.1% | Under (15–20) |
| Visceral fat level | 2 | Optimal |
| Intracellular fluid | 83.3 lb (65%) | |
| Extracellular fluid | 45.2 lb (35%) | |
| BMR | 2119 kcal | |
| TEE | 3263 kcal | |
| Left arm lean / fat | 10.92 / 0.49 lb | High / Under |
| Right arm lean / fat | 10.86 / 0.22 lb | High / Under |
| Torso lean / fat | 74.41 / 6.06 lb | High / Under |
| Left leg lean / fat | 26.61 / 1.50 lb | High / Under |
| Right leg lean / fat | 27.58 / 1.23 lb | High / Under |
| Upper-lower, left-right | Balanced | |
| Bio score | 82 | |
| BMI | 26.2 | (188.1 lb at 71 in) |
| Abdominal circumference | 27.8 in | |
| Waist-to-hip | 0.68 | Under (0.75–0.81) |

If you take the sheet as gospel: fat-free mass index ≈ 24.9 kg/m² (178.6 lb lean on 1.80 m). Natural bodybuilding FFMI bands in the literature often sit about 22.7–25.0. Skeletal-muscle index ≈ 14.0 kg/m². Abe 2018 saw a possible SM-index plateau near 17 kg/m² in very large athletes, with some men over 50 kg of estimated skeletal muscle and over 100 kg fat-free mass. This sheet is high. It is not the top of the human pile even if it is accurate.

It may not be accurate. InBody is bioelectrical impedance. A current through the body. Water, food, sweat, and a hard session move the number. Compared with DEXA, gym BIA is often quoted around ±3–8% body fat, and InBody commonly reads leaner than DEXA. A printed 5.1% could be 8–13% on an X-ray machine. That would drop lean mass and FFMI. The trend of “very lean, very much muscle for 188 lb” can still be true. The single-digit brag cannot be locked without DEXA.

Mineral 11.2 lb is not bone density. InBody’s own note: bone-density estimates are a 970-class claim, correlated to DEXA, not a 370 T-score. “Mineral” on this sheet is a compartment estimate, closer to a bone-mineral-content analog plus other minerals. Google called it Thor-density and +3–4 lb versus “athletic 7–8 lb.” The machine’s own range on the page is 8.2–9.9, flag High. That is the fair sentence. It is not a DEXA Z-score of the ankle.

Segmental balance (arms almost even, legs almost even, torso carrying the mass) is useful if the machine is consistent. Right arm fat 0.22 lb versus left 0.49 lb is a small oddity; could be noise.

Google’s “31% of bodyweight is skeletal muscle” is 100.3 / 188.1 ≈ 53% if you misuse SMM as a percent of total — or they meant something else. 100.3 / 188.1 = 53%, not 31%. The bot arithmetic fails again. SMM is not “pure muscle percent of a bodybuilding magazine.” Keep 100.3 lb as the printed line. Do not keep 31%.

Lab ask: one DEXA, same week as a calm InBody, fasted, no hard session. Then the mineral argument can graduate.

9. The men he named

These are case studies, not clones of Gene.

Oleksandr Usyk. About 6 ft 3 in. Long amateur career. Undisputed at cruiserweight (~200 lb). At heavyweight he has walked around 215–223.5 lb and beaten much larger men (Joshua ~240, Fury 260s). Size was a problem he solved with pacing, southpaw geometry, and an engine. Google’s “~200 then out-boxed 250+” is directionally right and sloppy on the exact walk-around weight.

Mike Tyson. About 5 ft 10 in. Prime fight weight commonly in the low 200s, not modern superheavy. Compact, high-pressure, short levers, vicious RFD. He is the poster for “not the biggest heavyweight.” He is not 180 lb, and he was a professional from childhood. Do not paste Gene onto Tyson.

Rich Froning Jr. 5 ft 9 in, listed 195 lb. Four-time CrossFit Games champion as an individual, then team titles. Published lifts in that era: snatch 300 lb, clean-and-jerk 370 lb, deadlift 545 lb. Google said “nearly 380” C&J and a VO2 of 73.9. The 370 is the number that shows up in profiles. The VO2 was not checked against a lab paper here — treat as unverified. He is the poster for a ~195 lb hybrid work engine. “Struggles over 200” is Gene’s read, not a metabolic law we measured.

Joseph Greenstein, the Mighty Atom. About 5 ft 4–5 in, 140–145 lb. Stage strongman: nails, chains, hair versus a plane, truck. That is tendon, skill, pain tolerance, and show construction. It is not a 105 kg snatch. It does wreck the idea that you must be 250 to be dangerous with your hands. Keep the feat-type honest or the example turns into a cartoon.

Itay Gil. Gene’s room: special forces, SWAT, black belts; Itay would kill everyone with his hands. Later: cane, stick, padlock, bat, sling; a stick is a weapon you can pick up anywhere; remaining hidden. That is skill, timing, and intent, which is what Krav-style work claims to train. The lab has no force plate on Itay. The lesson Gene took is the lesson: the most dangerous man in the room was not the biggest. Physics allows that. It does not guarantee it.

10. Will, hormones, rest, and what the average man can copy

From the car (life file, not a methods section). Two car accidents. Surgeon: may never walk. Coma. Cane. Limp. Heroin again in jail. Stabbed 21 times in a deal gone wrong (this is the same Traverse City line already in his other book). Prison for holding a pizza place. Did the things he was told he would not. Incarcerated much of his life. Shackles. 300 lb, barely walking. Then running, 20-mile work, circuits, hills, Cooper-style sessions, 45-minute runs, 45-minute boxing days. He has been trying to raise HGH by work, not by a vial: 30/30 jog-run, 10 exercises × 30 seconds no rest, one rest day. Wants calm heart and a still inside while the other man freezes. Learned 6 days on, 7th off from a boxing book, then fought for it. If you don’t rest you will not meet Yahuah. Wants the research to show human potential is farther than “typical,” and somehow open to the average man. Says done correctly, with discipline, it is simpler than the scientification of it.

What the lab can take:

Wolff / mechanostat: repeated load changes bone and tendon. A life of forced walking, shackles, labor, and later running is a loading history. That can thicken what is there. It cannot be separated, in this file, from the frame he was born with. Both/and, not either/or. “Not just genetics” is his stance. The tape at 9 and 11 still has to be explained; loading does not usually add two inches of wrist.
Cortisol versus testosterone: chronic grinding volume and no sleep will bury recovery. That is textbook. Exact ratios and “the only ratio that matters” are bot talk.
Growth hormone pulses: hard intervals and sleep move GH. 30/30 and circuits are a reasonable way to chase that. “Hydraulic bones from HGH work” is a story. Do not print it as endocrine fact.
Cold plunge before training: some studies show short-term catecholamine spikes. A guaranteed testosterone/LH protocol from a named “Dr. Tom” in a chatbot is not a paper we verified. Park it.
6 and 1 rest: as training, this is sane. Tissues need a day. As theology, it is his. The lab does not baptize Sabbath with cortisol curves. It also does not mock it. Fighting gravity seven days is a good way to get hurt.
Average man: skill, rest, and honest work are copyable. 9 in wrists are not. 21 stab wounds are not a training plan. Google saying “yes, if they accept the internal landscape” is a sermon. Gene’s hope stays Gene’s hope. The honest sentence: most of the method is copyable; the chassis and the history are not.

Cane and padlock as training tools: progressive threat, environment as weapon. That is motor learning. Filipino-martial-arts labels were the bot’s unless he said them.

11. What we can say, what we cannot

Can say

Ankle and wrist size are bone gauges. They set a mass ceiling better than they set a force score.
Gene’s tape (9 in / 11 in at 5 ft 11 in) is an extreme large frame by every common r-chart. r ≈ 7.89.
Butt’s later formula on that tape lands near 200–206 lb lean at 8–12% fat. That is a bodybuilding ceiling estimate, not a fight score. He currently walks 180–190.
Punch force is mostly floor, hips, timing, and how fast force rises. Bustance’s ankle cue is a fulcrum cue. It is not a dynamometer.
Square-cube / allometry: past a point, extra mass costs more than it buys for fight-and-work utility. 160–210 lb is a reasonable utility band, not a law and not a Golden Ratio.
Size does not determine ability. Weight classes exist for averages. Usyk, Tyson, Froning, Greenstein, and Itay (as told) all punch holes in “bigger always wins.”
The InBody 370 (12 April 2026) prints a very lean, very muscular 188.1 lb man with high mineral as the machine defines mineral. BIA is not DEXA. 5.1% fat is a machine number. Mineral is not a density scan.
Rest is not optional. 6 and 1 is a clean training rule.

Cannot say

That he has a Super-Athlete genotype, ACTN3 RR, or a typed IIa pile.
That 11 in ankles are metal-reinforced or that shackles grew the bone two inches.
That gyms refuse him because of insurance.
That 12,000 / 50 min is a ratified world record.
That he ran a 1-minute mile, or that 105 kg × 10 is elite powerlifting.
That InBody proved hyper-dense cortical bone.
That 160–210 is the peak of all human potential including yoke, superheavy, and climate-controlled lifting.
That the average man can copy the chassis.

Next measurements, if he wants the lab tighter

Re-tape wrist and ankle, both sides, three times.
DEXA (fat, lean, bone).
Optional: ACTN3 R577X.
Optional: force-plate punch or countermovement jump for real RFD.
Leave the nickname machine off.

13. One page you can keep

The tape on the ankle does not tell you if a man can fight. It tells you how thick the first pin in the chain is, and how much meat that skeleton might hang. Gene’s pins are thick. Butt’s math says that skeleton could hang a bit over 200 lb of lean if this were a bodybuilding problem. He does not live in that problem. He lives at 180–190, says he is more capable there than he was over 200, and he wants the useful human — not the giant, not the trophy.

Physics is on his side about giants paying a cube-tax. History is on his side that 200-and-under men have ruled rings and rooms. Google is not on anyone’s side. It will baptize a 10 km with a 1-minute mile if you let it.

What is copyable: rest one day in seven, stop muscling the punch, train the floor, keep the heart quiet until it is time. What is not copyable: a 9-inch wrist, a life that should have ended, and a coach from Kronk saying look at the ankle first.

The punch is still a lever. The lever still needs a pin that does not walk. The pin is not the punch.
