The system behind an online coaching business that lasts

Online coaching fails in the admin, not the programming. The client did not ghost because the squat was wrong. They ghosted because the week was late, the check-in vanished, and the invoice felt like another product.

One roster

Every client has a place. Active, quiet, paused. If you cannot see who went silent this week, you do not have a roster. You have a chat list.

One week

The program for this phase lives on the desk. Hand the week over in one tap. Draft the next block from the last one.

One thread

Sleep, weight, photos, how it felt. Reply once. Saved replies and AI drafts exist so Sunday night is not twelve identical paragraphs.

One way to pay

Packages they can buy. You keep the relationship. Platform fees that hide inside processing are how coaches lose the plot on margin.

A front door

A public studio page on your slug or your domain. An intake form that lands as a lead. A marketplace listing if you want strangers.

Questions

Do I need a separate CRM for personal training?
Not if the desk already has leads, forms, and a roster. Tarna keeps applications and check-ins next to the people they belong to.

Open a desk.

Five clients free. Studio is £49. Import a roster or start with one person and tomorrow’s session.
