The MMB Pro was created in collaboration with Mr. Mike "The Machinge" Bruce. We built upon the same patented Neck Flex platform to develop a harness that accommodates both plate loading and resistance band applications. The MMB Pro breaks the mold, a game changer. If you're serious about training, then step forward.
The Neck Flex® MMB Pro Series Kit is a heavy-duty, multi-patented head harness system engineered in collaboration with world-renowned neck strength expert Mr. Mike Bruce. Built on the advanced, medical-grade Neck Flex platform, it seamlessly integrates both progressive plate loading and resistance band training. This hybrid design delivers unmatched stability and safety, providing a comprehensive solution for complete cervical conditioning, elite athletic preparation, and injury prevention.
- Correct D-Ring Orientation: Features specialized "dog-ear" and vertically aligned side anchor points. This allows for a anatomically correct line of pull during lateral (side) neck flexion, unlike the flat, horizontal D-rings on the Alpha harness which cause slippage and bad training angles.
- Integrated Front Power Strap: Equipped with a crucial front power strap to lock the harness down. This keeps the unit from shifting or riding up your face during intense forward flexion and extension drills.
- Superior Material Integration: Constructed using premium, thick diamond-embossed neoprene padding and polished, welded heavy-duty steel D-rings. This resists degradation far better than the thinner, non-embossed fabrics used on cheaper rigs.
- Concussion Prevention & Impact Sports: Maximizes kinetic stiffness to buffer high-velocity rotational impacts in football, MMA, wrestling, and lacrosse.
- Advanced Hypertrophy & Bodybuilding: Promotes balanced muscular growth in the sternocleidomastoid, splenius capitis, and trapezius for a thicker, more powerful look.
- Chiropractic & Clinical Rehabilitation: Provides controlled, non-axial loading options for physical therapy, correcting forward-head posture ("Tech Neck"), and treating whiplash.
- Fast and Safe: The MMB PRO provides extremely fast results and is very safe to use. The fastest way to get a big neck and the safest way train neck
- The Patented MMB Pro Head Harness with adjustable multi-point straps.
- Heavy-Duty Weight Lifting Chain & Carabiners for direct plate loading.
- Bodylastics® Patented 19 lb Resistance Band with snap-reduction safety tech.
- Bodylastics® Door Anchor and an industrial Neck Flex Tote Bag.

Named in peer-reviewed research
When researchers ran a 20-week randomized controlled trial on 108 Royal Danish Air Force helicopter pilots and crew, they had to name their equipment in the methods section so that other labs could reproduce the work. The harness they named was ours: "a head harness (The Original Neck Flex® Head Harness, Gonzo Companies, USA)."
That choice was made during study design — before any results existed, by researchers with no stake in selling harnesses, for a protocol that ran three times a week for five months without supervision. Fit across 108 heads, load stability, padding and stitch integrity at the load points all had to hold, or the data would not.
