We ran 14 golfers through six weeks of training across three protocols — strength, mobility, and speed — and measured swing velocity before and after. The raw data is below. Including attendance. Including dropouts. Including the one participant who got slower.
We're publishing what worked, what didn't, and what we can't yet conclude. If you want to evaluate whether our coaching is worth your time, read the data, not the marketing.
The Speed group produced the largest average swing speed gain. Five participants, all retested, all gained — average +8.4 mph.
The Strength group was mixed. One participant got slower (Virosius, −2.4 mph). Menkar gained ~10 mph but also changed his shaft mid-study, so part of that gain is equipment.
The Mobility group dropped out. Only one of five (Auditia) completed the post-test. We can't draw a group-level conclusion from n=1.
Attendance predicted outcome. Participants with 12+ sessions gained on average; participants with fewer than 8 sessions mostly didn't retest.
Velocity gains scale with intent. The Speed protocol was the only one explicitly programming overspeed and max-intent swings every session.
This was not a controlled trial. No randomisation, no blinding, no control group. Treat it as a coaching report, not a clinical study.
Three groups, six weeks, three sessions per week. Same coaches, same studio, same SuperSpeed-style measurement protocol — five maximum-effort swings recorded before Week 1 and after Week 6.
Recreational and competitive golfers, mixed handicaps, ages 25–60. Self-selected into the group that matched their stated priority.
Three sessions per week for six weeks. Each session followed a circuit format with five to six stations, progressing in load and density across the block.
Five maximum-intent driver swings recorded pre-block (baseline) and post-block (retest). Numbers shown are individual recordings and five-swing averages.
The Strength block progressed from hypertrophy work in Weeks 1–2 (KB front squat, DB bench, posterior chain) into max strength (Weeks 3–4) and finished with neural density and contrast work (Weeks 5–6). Goal: build the force-producing engine that powers high club-head speed.
The Mobility block targeted hip and thoracic rotation, posterior chain length, and rotational speed. Sessions emphasised CARs, Cossacks, 90/90 flow, jump-rotation work and loaded mobility complexes. Goal: give athletes more room to accelerate through — and reduce energy leaks.
The Speed block worked the right end of the force–velocity curve: overspeed swings, light/heavy contrast, max-intent throws, jump rotation, reactive speed. Every session ended with maximum-intent driver-equivalent swings. Goal: teach the system to recruit fast.
Most "research-backed" claims you read online don't show their work. We're showing ours. Below is every theme, every circuit structure, every station — for each of the three blocks.
The Speed group's average gain (+8.4 mph) was higher than the Strength group's (+5.1 mph across finishers) and far higher than the Mobility group (n too small). This is consistent with the broader force–velocity literature: if the desired adaptation is speed, the stimulus should be speed.
Six weeks is short for strength adaptations to translate into club-head speed. Two of three Strength finishers gained, one didn't. Our read: strength is the foundation that lets speed work compound — but it's a 12-to-24-week story, not a 6-week one.
The Mobility group's dropout rate tells us we picked the wrong primary outcome. Mobility's job isn't to add speed in six weeks — it's to remove movement compensations that hide ceiling. We'll re-run this block with rotational range, separation, and ground reaction force as the measured outcomes, not raw mph.
Every participant with 12+ sessions either gained meaningfully or completed the post-test. Every participant who dropped out attended 8 or fewer. Programming doesn't matter if athletes don't show up — and showing up is partly a coaching responsibility, not just a client one. That's on us.
This isn't a randomised controlled trial. There was no control group, no blinding, and participants self-selected. Treat the numbers as an honest report from a coaching block, not as proof of mechanism. The protocols, the data, and the caveats are all here so you can judge for yourself.
Our next 6-week speed block opens for assessment booking now. We'll measure your baseline, build your programme around your limiter, and re-test at the end. You'll see your own numbers — and they'll go into the next study.
