Do I need SQL knowledge to see my progress?

While the skill uses DuckDB for analysis, you can use simple natural language prompts to have Claude run the necessary SQL queries for you to visualize your progress.

What happens if I make a typo in an exercise name?

The skill includes a validation step that checks your input against a reference list and suggests corrections for common typos to keep your data clean.

Can I add my own custom exercises?

Absolutely. You can expand the exercise list by editing the reference file to include your specific movements, categories, and validation rules.

How does the Fitness Tracker skill store my data?

It saves workout logs as Markdown files directly to a GitHub repository or a local Obsidian vault, ensuring you maintain full ownership and version control of your data.

Can I use natural language to record my sets?

Yes, you can enter sets naturally like '135 for 10, 10' or '30 minutes cardio', and the skill will automatically parse them into a structured format.
