A short review of what independent gyms do when a booked spot goes empty, and what the evidence supports. Claims without a source are marked, not smoothed over.

01 · The questions
How long should a hold last before the offer moves on?
Does reaching out beat waiting for members to check?
02 · What the sources say
A short hold beats a long one: offers that expire under fifteen minutes are accepted more often than open-ended ones. [1]
Most desks keep a phone list because the software never reaches out. [2]
No-shows cluster at the same times every week, so the list can be primed before the rush. [3]
Roughly half of released spots refill when the list is offered automatically. [4]
The list was never the problem. The silence was. [2]

[unsourced]
That a text message beats a push notification is repeated often and was not supported by a source I could open. It stays marked until it is.
05 · What this changes
Hold at ten minutes, in the middle of the supported range.
Reach out first. Do not wait for the member to check the app.
