Everything your scheduling calendar should do

Week calendar for sessions

See every booked training, nutrition review, and consultation session on a week calendar. Set the visible hours to match your own availability or your gym’s opening times.

Sessions tied to the client’s plan

Book a session against a specific client membership, so every appointment sits next to the workout and meal plan that client is following. No separate contacts list to keep in sync.

Recurring sessions

Mark a session as recurring once instead of re-booking the same client slot every week.

Session status tracking

Track each session as scheduled, completed, cancelled, or no-show, so attendance history builds itself.

Three appointment types

Schedule training sessions, nutrition reviews, or consultations. The calendar adapts to however your business books clients.

Coach session notes

Log how a session went right after it ends, building a private history per client alongside the booking.

Included on every plan — from €19.99/month

Training session scheduling ships with every Theron plan, no add-on required. Pricing scales per seat as your client list grows, billed pro-rated.

FAQ

Training session scheduling — common questions

What is personal trainer scheduling software?▾
Personal trainer scheduling software lets trainers, gyms, and nutrition coaches book and manage client appointments, whether those are training sessions, nutrition reviews or consultations — instead of texts and paper diaries. In Theron it is built on top of the workout and nutrition plan builder rather than sold as a standalone calendar.
Is Theron a calendar app?▾
No. Theron is a workout builder, nutrition builder and diet planner for coaches. Scheduling is one feature inside it, not the product. If you only want a standalone booking calendar, a dedicated scheduling tool will fit you better.
How does scheduling connect to the plan builder?▾
Sessions are booked against a client record, so a booked session sits next to the workout and meal plan that client is following, their logged progress, and your notes from last time — instead of living in a separate booking app.
Can I set up recurring training sessions?▾
Yes. Mark any session as recurring so a client’s weekly slot stays booked without re-creating it every time.
Does the calendar track attendance?▾
Yes. Every session has a status of scheduled, completed, cancelled or no-show, so you get an attendance history for each client automatically.
Can I book different types of appointments?▾
Yes. Theron supports training sessions, nutrition reviews, and consultations, so trainers and nutrition coaches can use the same calendar for different appointment types.
How much does the scheduling calendar cost?▾
Training session scheduling is included in every Theron gym plan, which starts at €19.99/month for 10 client seats. Prices exclude applicable taxes.
