AI Check-Ins work using a powerful smart placeholder system. These placeholders dynamically pull real client data from Trainerize and FitMetrics to generate highly personalized messages — without any manual typing.

What Are Placeholders?
Placeholders are little tags like ##{{client_full_name}} that automatically pull and insert specific client data into your check-in template. Instead of writing a custom message for each person, the AI does it for you, using the data you've already collected.
For example:
##{{client_goal}}becomes "Weight Loss"##{{avg_calories_eaten}}becomes "1850 kcal"##{{weight_progress_since_start}}becomes "-3.5 lbs"
There are 100+ placeholders covering everything from macros and workouts to sleep, heart rate, wearables, and compliance.
Where to View the Full Placeholder List
To see all available placeholders:
Go to AI Check-Ins → Templates
Open a template and use the placeholder toolbar at the top of the editor
You'll see every placeholder grouped by category:
Client Info — name, age, height, city, goal, program start date, trainer, tags, BMR, BMI
Weekly Info — week start/end dates, week number
Weight & Body Composition — current weight, body fat %, lean mass, fat mass, BMI, progress since start
Nutrition — calories, protein, carbs, fat, fiber, sodium, sugar, compliance, totals, remaining
Workouts — completed, scheduled, compliance %, cardio, steps, volume comparison
Habits — completed, scheduled, compliance %
Health — resting heart rate
WHOOP — recovery, HRV, strain, heart rate, calories, SpO2, temperature
WHOOP Sleep — sleep hours, deep/REM sleep %, performance, consistency, efficiency
Oura Ring — readiness, activity score, steps, sleep score, HRV, heart rate, temperature
Forms — form name, submission date, Q&A, personalized form links
AI Custom — custom AI prompts you create in the AI Prompts tab
For the complete list of every placeholder, see the article AI Check-Ins: Complete Guide to All Placeholders.
How to Add Placeholders to a Template
When building or editing a check-in template:
Use the placeholder toolbar at the top — select a category, then choose a placeholder and click Insert
Or type
/in the editor to use slash commands to quickly search and insert placeholders
Or copy/paste any placeholder manually like:
Calories Goal: ##{{avg_calories_goal}}
Protein Intake: ##{{avg_protein_eaten_g}}These will turn into live values when the check-in sends.
See Real Data Preview
One of the most powerful features: you can select a client and see how each placeholder will look with real values from their data using the Test button.
This helps you:
Make sure the template reads naturally
Validate if data is being synced correctly
Quickly spot placeholders that return [Not Available] (e.g. if the client didn't track)
AI Feedback Placeholder
One special placeholder is ##{{ai_coach_feedback}} — this generates an entire paragraph using AI based on the client's weekly performance.
The smart part? If a client is marked as on vacation, injured, or sick using the Compliance Tracker, the AI will detect this and adjust the tone. For example, if the client is injured, the AI won't ask them why they skipped workouts — it'll suggest recovery tips instead.
You can also create your own custom AI prompts in the AI Prompts tab for different coaching styles (e.g., motivational, analytical, nutrition-focused).
That's why it's critical to keep the Compliance Tracker updated.
Use placeholders to save hours, deliver hyper-personalized messages, and never go back to writing check-ins manually again.
