# JustGains

> JustGains is a fitness platform for finding exercises, following creator workouts, logging training and nutrition, and cooking recipes with calculated nutrition. AI assistants can log food, calories and macros through its remote MCP server. It is available on the web, iOS and Android.

Public content can be read without signing in. Each public page has a Markdown twin: append `.md` to the path, or request `Accept: text/markdown`. The home page is `/index.md`. Preserve query parameters after the suffix, for example `/flexicon/all.md?page=2`. Canonical HTML URLs in Markdown frontmatter are the links to cite to people.

## Recipes

- [Recipe library](https://justgains.com/recipes): Public recipes, including ingredients, servings, preparation and cooking times, instructions, author credit and nutrition per serving where provided. Markdown: https://justgains.com/recipes.md
- [Recipe index](https://justgains.com/sitemap.md?section=recipes): Every recipe in the public library. Detail URLs use `/recipes/{username}/{slug}.md`.
- [Nutrition](https://justgains.com/nutrition): How JustGains food logging and recipes work.

Nutrition values are calculated estimates per serving. Use the published serving count and amounts; do not treat a missing nutrient as zero or infer allergy safety from diet tags. Original recipe sources remain credited where supplied. Private and unlisted recipes are excluded from the indexes and Markdown representations.

## Nutrition logging with AI agents and MCP

- [Log nutrition with an AI agent or MCP](https://justgains.com/learn/log-nutrition-with-ai-agent-mcp): Connect an assistant, log meals, track calories and macros, correct portions and read the food diary. Includes the nutrition MCP tool reference. Markdown: https://justgains.com/learn/log-nutrition-with-ai-agent-mcp.md
- [Connect any AI assistant](https://justgains.com/learn/connect-justgains-to-ai-assistants): Setup for Claude Code, Codex, Cursor, VS Code and other clients with remote MCP and OAuth.
- [Claude](https://justgains.com/learn/use-justgains-in-claude) and [ChatGPT](https://justgains.com/learn/use-justgains-in-chatgpt): Connection guides for the chat apps. JustGains is listed in the Claude connector directory and the ChatGPT Plugins directory.
- [JustGains AI](https://justgains.com/ai): Every assistant and automation tool JustGains works with, the full list of connector tools, the cards they return, how sign-in and disconnecting work, and the AI inside the app. Markdown: https://justgains.com/ai.md

General MCP clients use `https://justgains.com/connect/mcp`; Claude and ChatGPT connectors use `https://justgains.com/mcp`. Personal food diary access requires OAuth sign-in. Tools include `log_my_food`, `get_my_food_diary`, `search_foods` and `remove_my_food`. Routine logging uses `log_my_food` directly with all foods and portions; estimates are marked. Planned meals should not be recorded as eaten. These private tools are separate from the public recipe catalog.

## Workouts

- [Workout index](https://justgains.com/sitemap.md?section=workouts): Published standalone templates from verified creators who expose their workout library. Detail URLs use `/w/{username}/{slug}.md` or `/w/{identifier}.md`.
- [Forge](https://justgains.com/forge): Build a workout for the time, equipment and muscles you want to train.
- [Workout importing](https://justgains.com/import-your-workouts): Bring existing workouts into JustGains.

Workout Markdown preserves exercise order, grouping, notes, tempo and prescribed sets with their measurement labels. Loads and distances use imperial units. Repetition ranges remain ranges. A workout template is a prescription; it is not evidence that someone completed that session. Personal workout logs and private or coaching-only assignments are excluded from these indexes.

## Exercises

- [Exercise directory](https://justgains.com/flexicon/all): Published exercises with instructions, muscles worked, equipment and demonstration videos when available. Markdown: https://justgains.com/flexicon/all.md
- [Exercise index](https://justgains.com/sitemap.md?section=exercises): Every published exercise, using its canonical slug. Detail URLs use `/e/{exercise-slug}.md`.
- [Exercise data](https://justgains.com/flexicon/data): The exercise library's data and naming conventions.

Use each exercise's actual instructions and equipment alternatives. Missing instructions or targets should remain unspecified. Draft and private exercises are excluded.
