How to build a personal fitness tracker in Bubble

A personal fitness tracker in Bubble is built by creating a Workout data type, letting users log exercises through a simple form, saving everything to the database, and then showing progress using repeating groups and charts. The core idea is: users create entries, Bubble stores them, and you display progress back to them.

Data Structure Setup

Create these data types so Bubble knows what information to store. A “data type” is like a spreadsheet table.

• Workout: fields: Date (date), Exercise (text), Reps (number), Weight (number), Owner (User)
• User: comes built‑in; no changes needed

Set Privacy Rules: In the Workout type, enable “This Workout’s Owner is Current User” and allow them to view and modify their own entries.

Creating Workout Entry Form

On a page, add input elements for exercise, reps, weight, and a date picker. Add a button “Log Workout”. In its workflow, use Data → Create a new thing → Workout and map each input’s value to the new Workout fields. Set Owner = Current User.

Showing Workouts Back to User

Add a Repeating Group (RG). Its data source should be “Do a search for Workouts” with the constraint Owner = Current User, sorted by Date descending. Inside the RG, show the exercise, reps, weight, and date.

Adding Progress Charts

Install the “Chart” plugin from Bubble. Add a chart element and set its data source to the same “Do a search for Workouts”. Choose the X‑axis as Date and Y‑axis as Weight or Reps, depending on what progress you want displayed.

Optional: Automatic Daily Reminders

Set up a backend workflow: In Backend Workflows, create an API workflow “send\_reminder”. Use an email action. Then schedule it using “Schedule API workflow” triggered daily from an admin page or using Bubble’s Recurring Events feature.
