AI Check-Ins allow you to create fully personalized, data-driven weekly messages using placeholders. This guide explains every available placeholder and how to use them effectively.

What Are Placeholders?

Placeholders are special codes that automatically get replaced with real client data when an AI Check-In is sent.

They look like this:

{{avg_calories_eaten}} {{client_first_name}} {{workouts_completed}}

Example:

Hey {{client_first_name}}, great work completing {{workouts_completed}} workouts!

becomes:

Hey Sarah, great work completing 5 workouts!

This allows you to write one template that dynamically customizes itself for every client.

Data Timeframe (Important)

Most placeholders automatically follow the Data Timeframe you select in your template:

This Week
Last Week
This Month
Last Month

This ensures all data inside your check-in refers to the same period.

❗ Important Note About Missing Data

If a client doesn't have data for a placeholder, FitMetrics displays [Not Available]. Placeholders like {{client_starting_weight}}, {{client_goal_weight}}, {{client_goal}}, and {{client_starting_body_fat}} must be filled in manually from Trainerize Clients at https://app.fitmetrics.ai/business/trainerize-clients by finding the columns. Anything else that shows [Not Available] means that information hasn't been filled in from Trainerize, which means the client needs to provide the information.

AI placeholders automatically adjust their coaching message to mention missing data gracefully.
