Happy Monday AAC Team! We are 1,202 strong today, up from 1,166 last Monday. That is 36 new faces and we officially crossed 1,200... so freaking cool! Welcome to everyone who just joined! First, the big one. The 4-Week Fitness App Challenge is officially open inside Athlete AI Labs! Doors opened this morning: Join the 4-Week Fitness App Challenge Quick version of what it is: - 4 weeks, from your idea to a real app on your phone or the web - the app or AI agent you always wanted - Every step is a prompt you run, in order. No code background needed - Live build calls twice a week with me and everyone else building - Two 1:1 reviews with me, one on your idea and one on your plan - Lifetime access. You pay once and you have it all The first 20 seats are $249 and those 20 also get a weekly call with me every Wednesday plus my AI fitness agent. After that it's $349. Doors close Sunday night at 11:59pm ET and I honestly don't know when they open again. And same as always - the Athlete AI Community here stays free. That is not changing. Secondly, a recap of what we pushed last week in case you missed something: - 6 apps Claude can replace in a weekend - open source replacements for Strava, Whoop, MyFitnessPal, Hevy, TrainingPeaks and Zwift. One honest update: I set up SparkyFitness (the MyFitnessPal one) today to demo it and it was really weak. I would not recommend that one - I let Claude replace Strava - my own server, my own data, my own feed - 20 things you need to know to actually train with AI - The 5 biggest mistakes people make when using Claude or ChatGPT to train & how to fix them - 8 things you can do when you connect Whoop to Claude Code - On a personal note - I am pain free when running for the first time in nearly 2 months. NYC here we come!
