Who signs up for AFT webinars
Nine webinars, 654 registrations, 352 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.
The series

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” fell from ~17% to ~5% by August, then ticked back to 10% in September — a dip rather than a collapse.
Only a fifth of registrants give a CIMSPA number
The field was added from Jan 2026 and is optional. Across the eight webinars that asked, 122 of 548 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 75 people carries the series
221 of 352 people came once and never again. But 76 have registered three or more times, and one person has registered for all nine. 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
1,195 YouTube views against 654 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. Views arrive early and then stop: in the eight weeks to 20 Oct, every replay more than five months old gained at most 0.05 views per registrant, while August’s gained 0.45. So the older replays have settled, and among those the fall from 2.7 views per registrant (Nov 25) to 1.0 (May 26) is real. The newest — Sep 26, 26 days old — is still climbing.
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.

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.
- 52 duplicate bookings removed. The same person booked twice for the same webinar 52 times — 12 in July and 11 in August alone. Raw export totals overstate the room by roughly 7%.
- 21 people use more than one email address. One booked under three addresses and 20 under two. Distinct-person counts are therefore approximate, and email-based deduplication alone would have said 374 rather than 352.
- The consent question changed in Sep 2026. The first eight webinars asked registrants to tick “Sign me up to receive further emails from AFT”. September asks them to agree to joining the list as part of booking. The 86% that month is therefore not comparable with the 28–58% before it, and the two should never be averaged or trended together.
- Role is self-selected and unstable. 27 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.
