This only partly worked. Worth knowing before you try it.
The AI analyzed my whole genome in 30 minutes for about $5
A Stanford doctor gave the AI his own genome file and a 180 word prompt based on the framework his team published in 2009.

Coach my running from my real Garmin and Strava data
A runner replaced uploading Garmin screenshots into AI with a self-hosted agent on a Mac mini that reads his Garmin data (sleep, HRV, resting heart rate, VO2 trend, laps) through MCP plus his Strava uploads: it messages him at 8am, designs the day's run and writes it to Garmin Connect, then grades each session against the prescription when it lands on Strava and decides when training load goes up. He hit his sub-20-minute 5K goal about a month later, and it saves him the hour a week he used to spend planning.

Simmons asked László to learn his Zone 2 method from his training community and analyse three months of pace and heart-rate data ahead of the New York City Marathon.

My agent plans my workouts from my calendar and my own results, and I cancelled 20 dollars of subscriptions
A man set the AI to pull each week's workouts from training providers he used to pay for, since they post the sessions free but late.

A few weeks in it is saving him 20 dollars a month in subscriptions.
