Capped sessions
Set the exact capacity for each small-group session so quality stays high.
For semi-private & small-group
Software for small-group & semi-private training
Fill every spot. Run capped small-group sessions with waitlists, class packs, and reminders — the model between personal training and big group classes.
Semi-private and small-group training — 3 to 6 people per session — is one of the best business models in fitness, but it lives or dies on filling spots. You need tight capacity control, waitlists that auto-fill cancellations, and class packs that make it easy for members to keep coming back.
Flex handles the small-group model end to end: cap each session, run a waitlist that promotes automatically, sell class packs and memberships, and remind members so seats don't go empty.
Sound familiar?
The day-to-day headaches Flex is built to remove.
Empty spots cost you
Caps plus automatic waitlists mean a cancellation gets backfilled instead of leaving a paid seat empty.
Tracking class packs by hand
Sell class packs and let credits draw down automatically as members book — no punch cards or spreadsheets.
No-shows in small sessions hurt more
Automatic reminders (email, plus SMS on Studio and up) keep small sessions full.
Juggling tools
Booking, payments, and member accounts in one place instead of three separate apps.
How Flex helps
Automatic waitlists
When someone cancels, the next person is promoted and notified automatically.
Class packs & memberships
Sell packs and memberships; credits draw down as members book.
Reminders that fill seats
Automatic reminders before each session reduce no-shows and keep groups full.
Branded website
A site on your own domain where members discover, book, and pay for sessions.
Small-group studios usually pick the Studio plan ($129/mo) for SMS reminders, a custom domain, and up to 10 coaches.
