Building a daily agenda

The daily plan endpoint is designed for building a "today" screen. It combines data from the user's active workout plan, nutrition plan, and class plan into a single response so you don't need to make three separate calls.

# Workout Plans

AI-generated workout plans are saved to the user's account and broken down into daily workouts with exercises, sets, reps, and instructions.

# Generate Plan POST /users/me/workout-plan

Generate an AI-powered workout plan and save it to the account.

{
  "success": true,
  "data": {
    "planId": 1,
    "summary": "4-week intermediate strength program",

# Complete User Journey

Call POST /users/me/workout-plan and POST /users/me/nutrition-plan to generate personalised plans from the user's profile.

Show the user what is on their plate today with GET /users/me/daily-plan. Combine workouts, meals, and scheduled classes in a single view.

As the user completes workouts, log them with POST /progress/workout. Track meals with POST /progress/nutrition and water with POST /progress/water.

Fetch progress data with GET /progress and build dashboard visualisations showing trends over time.

# FAQ

Can a user have multiple active plans?

A user can have one active plan of each type: one workout plan, one nutrition plan, and one class plan. Generating a new plan replaces the existing one.

What happens if the user's profile is incomplete?

The AI will generate plans with whatever data is available, but more complete profiles produce better results. At minimum, the user should have fitnessLevel and fitnessGoal set.

How is the daily plan built?

The daily plan endpoint combines data from the user's active workout plan (which day it is in the programme), nutrition plan (meals for that day), and class plan (scheduled classes). It is a read-only view -- changes are made to individual plans.
