Workout builder and diet builder in one tool
Most coaches rebuild similar gym programs and meal plans from scratch for every new client. Theron gives you a workout builder and a diet builder over the same template library: build a plan once, save it, and assign it to any client with one click.
Build your first template — from €29.99/moWhy templates save real coaching hours
If your clients share similar goals, their plans share a lot of structure. Rebuilding that structure by hand for every new client wastes hours that could go into actually coaching. A template library turns that repeated work into a one-click assignment.
How the workout builder and diet builder work
Build a plan
Use the workout builder for exercises, sets and reps, or the diet builder for meals and macro targets — manually, or starting from an AI-generated plan.
Save it as a template
Store it in your template library for reuse.
Assign to a client
Pick a client and assign the template with one click.
Customize per client
Tweak the assigned copy for that specific client without touching the original template.
Build once, reuse forever
Stop rebuilding the same plan structure for every new client.
One-click assignment
Assign a saved template to any client instantly.
Editable per client
Customize the assigned copy without changing the master template.
Works for both meal and workout plans
One template library covers both plan types.
