Show HN: SigmaLifting CLI – helping agents understand strength training

Hi HN, I built the SigmaLifting app a while ago. Seeing the recent rise in agentic tools, I decided to extract its core engine into a CLI using the same underlying protocol. Powerlifting programming is really just structured data. The CLI lets your agents manage it entirely in the terminal using plain JSON for local storage, with built-in validation. The main idea is that it separates the program (the reusable template) from the process (your actual workout logs). Since everything is just JSON, it’s easy to pipe your training history straight into a script or an LLM for analysis. Would love to hear what you guys think!

I've done something similar locally.

I've used a lot of exercise science data that I've pulled from various sources and "trained" and agent to construct my workout program based on goals, current health, etc., all also pulled in from various data sources.

My focus lately has been mobility, so guys like Vernon Griffith have been some of main training material for my local agent.

I would love if this could be monetized for the creators/knowledgeable folk. So that e.g. Vernon could get a commission when an agent uses his knowledge.

Anyway, great that you've published this! I hope you extend it further. ...mine is currently expanded toward cardio and overall health. I love it :)
