You're probably a lot like me.
Tired of out-of-the-box training apps
Every plan is generic. None of it fits how you actually train, and you end up working around the app.
Done with coaching that doesn't fit
Coaches who don't really care, or don't really know what they're doing, handing you the same plan as everyone else.
Waiting on someone else to build it
You know exactly what the app should do. Nobody is going to make it for you.
Curious how to actually use AI
You've tried the chat apps. But you know there's more, and you want to learn.
Then AI changed it
So I built my own.
AI let me build my own fitness agent. It reads my data, knows my training and tells me what to do each morning. I learned how to build it one step at a time, and that is exactly what I teach you in here.
How it works
01
Pick your idea
Your own app idea, a better version of an app you already use, or an AI agent for your own training.
02
Follow the videos
35 step-by-step videos take you from idea to a real app. Every step is a prompt you copy, paste and run.
03
Build with us
Live build calls every Tuesday and Thursday, two 1:1 calls with me, and a room of athletes building next to you.
04
Put it on your phone
In 4 weeks you have a real app on your own phone. Yours to use, share and keep improving.
Join the Challenge waitlist

Already built by members
Athletes shipping their own AI coaches.
All of this came out of the free 7-Day Challenge in the Athlete AI Community. Labs is the next step: a real app, on your phone.
A 5:05 AM routine that runs itself
Added recovery and nutrition coaches, then automated Withings, Garmin, a recovery call, and a nutrition plan into one morning task.
The whole system, moved to the cloud
Finished all seven days, then rebuilt it on Vercel and Supabase with AI planning, daily check-ins, and weekly reviews.
Trends a chat app would miss
His coach pulls similar workouts from a year back and watches for real patterns in his training.
Fitness and fuel in one dashboard
Race readiness, her training plan, and fuel targets, built while coming back from hip surgery.
“Training-life-changing”
A thank-you to the whole community after building his Athlete OS from the free tutorial.
And the thank-yous keep coming.

Why people build
The app you keep wishing existed? You can build it now.
Nobody knows what your training needs better than you do. Most people show up for one of three reasons.
You have an idea
It's been in your notes app for a year. You know exactly what it should do. You just never had a way to make it.
You know you could do it better
You use the same training app every day and you can list what's wrong with it. Build the version that works the way you train.
You want to build for yourself
No big plan. You want tools for your own training, something to show your friends, and the skill to make the next one.
WHAT CHANGES ONCE YOU'VE BUILT ONE
- You stop waiting for an app to add the feature. You add it.
- You start seeing problems everywhere, and you know you can build the fix.
- Your training runs on something you made, built around how you actually train.
- You keep the skill. Building with AI is one you'll use for the rest of your life, long after this app.
- You get excited again. The kind you had when you signed up for your first big race.
That feeling is the whole point of Labs.
Who's teaching this
Kevin Rudd.
D1 LACROSSE · ULTRARUNNER · FOUNDER, ATHLETE AI
I am a former Division 1 lacrosse athlete who found endurance sports after graduation and fell in love with them. Ultramarathons, Ironmans, multi-day treks. Pushing my body and my mind is the thing I keep coming back to. I love it.
As I dove into the endurance world I kept hitting the same problem: nothing was built or customized how I wanted. In college, everything around me was elite and my training was dialed in. In endurance sports, I couldn't find coaching that came close. Apps were too generic. Close friends in the space didn't have enough experience. The influencer coach cared more about going viral than training me. And the elite coach's attention was focused on their Olympic athletes.
So I stopped waiting on someone else. I learned to build with AI, failed for a couple long months, and eventually came out with my own AI coach. It reads my Garmin and Whoop data daily, writes my NYC Marathon plan, pushes every workout to my watch, and checks in with me on Telegram each morning. It knows me better than I know myself and it's transformed how I view the world.
I built it with Claude, one prompt at a time. Labs teaches you that exact process, applied to your app idea. Every lesson comes with the prompts I use, so you're not collecting AI tips. You're shipping. Doing it alongside other athletes just like you and me.

Questions
FAQs
Do I need to know how to code?+
No. Every step is a prompt you run with Claude, in order. If you can follow a training plan, you can follow this.
Do I need an app idea already?+
Bring one, and rough is fine. "The app I already use, but better" counts. So does a tool for your own training. Phase 2 cuts it down to something you can actually ship.
Do I have to sell it or start a business?+
No. Build it for yourself, your training partners or your team. The payments and launch lessons are there if you ever want them.
Phone app or web app?+
Either. You pick your track at the start. The mobile track takes an iPhone app to App Store submission and an Android app to Google Play's testing track. The web track skips the app store fees.
What does it cost beyond the seat?+
About $175 to get started if you build for iPhone, about $100 for Android, and about $75 for a web app. That is Claude Pro at $20 a month (Claude Code comes with it), Mobbin Pro for the design phase at about $45 a quarter, a domain at about $10 a year, and one store account: Apple Developer at $99 a year or Google Play at $25 one time. You only pay for the phone you are building for, and a web app needs neither. Mobbin and the domain are recommended, not required: you can screenshot apps on your own phone for free, and the free address your host gives you works. Everything else runs on free tiers while you build. One to know about: once your app starts charging, Vercel (where your site is hosted) asks you to move to its $20 a month plan.
What if it's not for me?+
You're covered by a 7-day money-back guarantee. Join, get into the first lessons, and if Labs isn't what you expected, email us within 7 days of joining for a full refund. No hoops.
How long does it take?+
It's self-paced with lifetime access. The core path from idea to a finished app is built around 4 weeks.
