A Timeline of Neck Training

1890s — apparatus before instruction

1891. US Patent 450,188, “Neck-Exercising Apparatus,” granted 14 April to Theodore Peterson of Akron, Ohio, assigned to The Howard Manufacturing Company. A leather head harness with pivoting side straps running to gym wall-pulley weights. The earliest known device made solely for exercising the neck, and it was a commercial product, not a prototype.

1893. US Patent 500,686, “Gravity-Helmet,” granted 4 July to John F. Corker of Salt Lake City. Weighted rims shaped to the sides of the head. Justified by the observation that people who carry loads on their heads hold themselves more erect.

1896. US Patent 559,270, granted 28 April to George O. Edwards of Oakland. Moves the resistance line to the crown so the head can move “in every possible direction Without danger or liability of disarranging the headstall.”

1897. Eugen Sandow publishes Strength, and How to Obtain It. It contains no neck exercise. Pupil testimonial tables record neck circumference, so the measurement was considered worth taking — but the most famous physical culturist of the era prescribed nothing for it.

1900s–1920s — the wrestlers write it down

1906. US Patent 821,783 to Frederick Meredith Clease. Wall-anchored elastic cords with a webbing cap. Elastic neck resistance, patented.

1908. George Hackenschmidt publishes The Way to Live, containing a five-exercise neck series with complete dosage: self-resisted isometrics progressing from five repetitions to twenty, a barbell press from the head bridge at 30–50 lb progressing three reps to ten before adding five pounds, and a belt-loaded quadruped exercise from 10 lb. The full transcription is here. The first complete progressive-overload scheme for the neck on record.

1913–14. Martin “Farmer” Burns publishes Lessons in Wrestling and Physical Culture, which treats neck strength as central to wrestling. A caveat on this entry: the widely circulated digital copy is a scan of printouts from a defunct website rather than of the original book, and its optical character recognition is too degraded to quote. A verified scan is still being sought.

1924. Earle Liederman publishes Muscle Building with a dedicated chapter, “The Structure and Development of the Neck.” He argues that a strong neck is less likely to break in a fall — an injury-resistance claim made eighty years before anyone measured anything relevant to it. He also claims neck development improves blood supply to the brain, which is not supported.

1924. Alan Calvert publishes Super Strength. Twenty-six chapters covering back, legs, sides, abdomen, chest, shoulders, arms, grip and hands. No neck chapter.

1924. US Patent 1,517,147 to Alfred E. Burnett — coil-spring resistance headgear, described as “a device utilized primarily for the development of the neck muscles.”

1925. US Patent 1,543,346 to Henry W. Titus. Elastic strands can be added “as the muscles of the neck increase in strength, thus the device becomes a progressive exerciser.” The first patent to claim progressive resistance for the neck as an invention — seventeen years after Hackenschmidt published a more sophisticated progression for free.

1926. George F. Jowett publishes The Key to Might and Muscle, containing Chapter XI, “How a Columnar Neck Creates Nerve Force.” The high-water mark of pre-scientific justification.

1930s–1960s — the medical branch splits off

1936. US Patent 2,051,366 to John H. Catron. A helmet carrying a rotating weighted arm; head movement spins it and centrifugal force cyclically loads the neck. The most mechanically unusual device in the record.

1949. US Patent 2,475,905 to Albert H. Lowry — a chin-and-occiput harness the user pulls upward by hand. Self-applied traction framed as exercise. From here the training and traction lineages run in parallel and borrow each other’s vocabulary, which is the origin of a good deal of modern product confusion.

1957. US Patent 2,791,999 to Cesar Bustamante, explicitly aimed at home use: the device can be “administered at home” and the forces “regulated or controlled by the patient himself.” Note the clinical vocabulary — treatment, patient — for what is an exercise device.

1958. US Patent 2,855,202 to Marvin A. Kinne mounts the weights directly on the head frame so that “the head to be moved in any direction.” The free-loading argument that still divides the equipment market.

1961. John Sharkey files two neck patents on the same day — one a sand-filled sheath over a football helmet, one a helmet taking nesting metal weights. Two materials, one problem, filed together: evidence of a commercial product line aimed at football.

1964. US Patent 3,118,667 to Lidija Barons — a bite-block gripped in the teeth, loading the neck through head rotation. The teeth-and-jaw lineage, patented.

1970s–1990s — the crash researchers arrive

Through this period the most consequential work on the cervical spine is not done by anyone interested in training. Automotive safety research establishes what the neck actually tolerates: Mertz’s compression figures from tackle-block impacts in 1978, Nyquist’s tensile threshold from collision reconstruction in 1980, and Yoganandan’s cadaveric tension testing converging on roughly 3,373 N in 1996.

These numbers, summarised on the injury tolerance page, remain the best data in existence on cervical structural limits — and they were produced entirely outside sport.

1999–2010 — criteria and the first hard questions

1999. NHTSA publishes the Nij criterion, combining axial force and bending moment into a single value, with intercepts for six occupant sizes. Nij of 1.0 corresponds to roughly a 22% risk of serious neck injury. It becomes the reference standard for essentially all subsequent work.

2004. The US Air Force School of Aerospace Medicine publishes the review that defines the modern training question. It establishes the angular thresholds — joint reaction forces rising rapidly beyond roughly 15° flexion, 30° extension, 35° rotation — measures neck muscles operating at up to 257% of maximum voluntary contraction in flight, recommends specific and intensive resistance training, and states plainly that no prospective controlled trial in fighter pilots had ever been conducted.

2007. Netto and colleagues match gym exercise intensity against in-flight muscle activity by electromyography, and find that elastic band resistance of any grade produces roughly 15% MVC — the equivalent of one G.

2019–2026 — the evidence base fills in

2019. MRI of six crew members returning from an average of 166 days in space finds neck muscles larger, not smaller — trapezius up 25.1%. Whatever drives cervical adaptation, it is not simply the load of holding the head up.

2020. A randomised controlled trial with Royal Danish Air Force helicopter aircrew runs twenty weeks of neck and shoulder training. The trained group gains cervical extension strength; the reference group loses it. Only 29% of participants train regularly, and those who do roughly triple the effect. The trial’s equipment list names a Neck Flex® head harness.

2020. A six-week rugby trial publishes the most completely specified neck protocol in the literature — exact sets, reps, hold times and autoregulation scale. Its control group declines on every measure.

2021. Twelve weeks of training in high-performance aircraft personnel produces MRI-confirmed muscle volume increases of 6.6–8.3% and, more importantly, a significant reduction in the muscular effort required to hold the head up under helmet load.

2024. USAF student fighter pilots complete an eight-week programme of ten to fifteen minutes, three times a week. Cervical endurance improves 33.6% overall and 55.7% at one base.

2026. The first clean head-to-head between weighted headgear and elastic bands, in 95 aviation cadets over twelve weeks. Both improve by week six. Only the weighted group keeps improving; the band group’s endurance effect size falls from 0.68 to 0.30 while the weighted group’s rises from 0.84 to 1.01.

What the shape of this timeline shows

Equipment preceded instruction by seventeen years. Somebody was manufacturing and selling neck apparatus in 1891, before anyone published a programme for using it. Demand existed that the literature ignored.

Wrestling carried the knowledge; physique culture did not. Hackenschmidt, Burns and Jowett wrote about the neck. Sandow and Calvert did not. The men who needed a neck to survive competition trained it; the men selling appearance largely skipped it.

The rationale was rebuilt three times. Postural carriage, then fall resistance, then nerve force, then measured tissue loading. The exercises stayed nearly identical throughout.

The rigorous work came from outside. Crash safety established what the neck tolerates. Aviation medicine established what training achieves. Neither was interested in fitness, and both produced better evidence than the fitness industry ever has.

Gaps in this timeline

The period between roughly 1965 and 1999 is thin here, and that is a limitation of this page rather than of history. American football’s neck-training culture developed in that window — the isometric neck machines, the neck rolls, the rule changes following the spearing injury crisis of the 1970s — and none of it is yet sourced to primary documents. NOCSAE standards and NCAA rule change records are the obvious next step.
