How it works

Invite clients

Add the clients you coach in person or online and give each one access to their own training space.

Every client has one place for their program, history, measurements, and notes. You keep the full context without spreadsheets, PDFs, and lost messages.
Create workouts

Create workouts, training blocks, or full programs with exercises, sets, reps, weights, rest times, and instructions.

The plan does not feel like another document sent in chat. Clients receive it in the app and know exactly what to do for every set.
Train

Log sessions during in-person coaching, or monitor online clients from the work they actually complete.

Previous performance, notes, and weights are with you when you need them. Every session connects to the last one.
Analyze

Track progress through workout history, volume, strength estimates, and measurements instead of guesswork.

You can quickly see when to push load, change an exercise, hold progression, or address a plateau. Your adjustments feel precise and professional.

FAQ

Can I use Onyx Coach for both gym clients and online clients?

Yes. You can log in-person sessions live and also deliver structured programs directly to online clients inside the app.

Do both plans include unlimited clients?

Yes. Both plans include unlimited clients and the same premium support. The only difference is the number of premium client slots.

Is this replacing my coaching, or just my admin stack?

It replaces the scattered tools around your coaching: notebooks, spreadsheets, PDFs, and repeated chat instructions. Your coaching decisions stay yours.
