Who signs up for AFT webinars
Eight webinars, 597 registrations, 339 distinct people. The audience has shifted from personal trainers to healthcare professionals, a third of it comes back, and CIMSPA numbers are supplied by almost nobody outside the PT segment. This covers registrations and replay views — the check-in column is empty in every export, so live attendance is still unknown.
Registrations per webinar, split by first-timers and returners
Sign-ups are lumpy rather than trending. The two biggest months (Nov 25, Feb 26) and the biggest recent one (Jul 26) are all months where more than half the room was new — growth here comes from reaching new people, not from the existing list turning out harder.
The room has tilted towards clinicians
Healthcare professionals were 37% of the Nov 2025 audience and 63% of July 2026's. The swing is topic-driven: clinical subjects (amputee training, gait, MS) pull physios and NHS staff, while the two most PT-heavy months were Phantom Limb Pain and Nutritional Therapy. “Other” has quietly collapsed from ~17% to ~5%.
Only a fifth of registrants give a CIMSPA number
The field was added from Jan 2026 and is optional. Across the seven webinars that asked, 107 of 491 registrants (22%) supplied a usable number. That headline is almost entirely a composition effect: nearly half of personal trainers give one, while healthcare professionals — now the largest group — essentially never do, because most are not CIMSPA members.
A core of about 60 people carries the series
219 of 339 people came once and never again. But 62 have registered three or more times, and two people have registered for all eight. May 2026 is the clearest read on that core: only 3 of its 40 registrants were new, so essentially the entire room was repeat audience.
The replay roughly doubles the room, but the pull is fading
1,060 YouTube views against 597 registrations — about 1.8 views per sign-up. Every replay is unlisted, so these are not new audience found through search or recommendations: they are the registrant list coming back, plus whoever they forwarded the link to. Read the bars with the age label in mind — Nov 25 has had 280 days to accumulate views, Aug 26 has had seven.
Five things worth acting on
Webinar by webinar
“Registrants” counts distinct people after removing duplicate bookings by the same person. “Came back” is the share of that webinar’s registrants who registered for at least one later webinar. “Days live” is how long the replay had been on YouTube when the view counts were read, and is the reason view totals are not comparable across rows.
| Webinar | Raw rows | Registrants | New | Returning | HCP | PT | CIMSPA | Opt-in | Non-UK | Came back | Views | Views/reg | Days live |

Data quality caveats
These figures come from booking exports, and several things in them need a caution flag before any of this goes in front of a partner or funder.
- 46 duplicate bookings removed. The same person booked twice for the same webinar 46 times — 12 in July and 11 in August alone. Raw export totals overstate the room by roughly 7%.
- 33 people use more than one email address. One of them booked under three addresses and four more under two each. Distinct-person counts are therefore approximate, and email-based deduplication alone would have said 364 rather than 339.
- Role is self-selected and unstable. 22 people picked a different role for different webinars, three of them moving between “Personal Trainer” and “Healthcare Professional”. Treat role splits as indicative, not exact.
