“I’ve got 3 slots this week.
I want to get stronger and run.”
01 / How it works
You already ask your AI for training advice.
Now give it somewhere to play.
Your goals, your gear, your schedule. In the ChatGPT or Claude you already use, build a program that fits your life.
“I only have 30 minutes this week.”Your program lands in TWAINING. Open your session and follow the exercises and rest timers. All that’s left is the work.
The right exercise. The right target. Right on time.Sessions, weights, runs, how it felt: your assistant sees your actual results. Ask for a recap, talk through next week, level up your program.
“Look at my week. What should we change?”02 / Built for real life
Less time. Bigger goals. A session that felt too easy. Just say so, and your program follows.
Turns out I only have 25 minutes tomorrow. Cut my lifting session down.
I kept the key lifts and trimmed the sets. Tomorrow’s session is updated.
Illustrative example · You stay in control of every change.
03 / A real app to get it done
When the session starts,
the app takes over.
Exercises, target weights and rest periods flow on their own. Pause or skip a step whenever you need to.
Distance, pace, GPS route, intervals. Your runs live in the same program as your gym sessions.
Your exercise and timer on the Lock Screen. Distance and pace while you run.
LIVE ACTIVITYOnce your program is loaded, train offline. Your results sync as soon as you’re back online.
WORKS OFFLINEYour steps from Apple Health, a daily goal and reminders to keep moving.
STEP TRACKING
The perfect program? The one you actually do.
Keep the flexibility of a conversation.
Get back the thrill of doing the work.
04 / Tracking that connects it all
Your training context shouldn’t reset every time you open a new chat.
Goals, equipment, habits, check-ins: your shared coaching profile gives the assistant you connect something real to work with. It also sees your sessions and results.
Your data stays under your control.
View and edit your profile, see every change, and disconnect an assistant right from the app.

Before you start
Your assistant can write a program. TWAINING is where you actually do it: exercises, sets, target weights, rest, GPS runs. Your connected assistant then sees your results, so it can look at what you really did and plan what’s next.
Connect your ChatGPT or Claude account to TWAINING, allow access to your training data, and build your program in your assistant. You keep the account you already use, and your sessions show up in the app. One connection links your conversations to your training.
Yes. You use your own ChatGPT or Claude account. Once TWAINING is connected and its tools are available in the conversation, ask your assistant to check your training or adjust your program. Your shared profile also helps a brand-new chat pick up where you left off.
That’s the idea. Your program can mix strength, running, burpees, core and mobility, including interval runs. Everything lands in the same history, so the next plan sees the full picture.
The assistant you authorize can view and manage your training data, including your notes and GPS routes. You can disconnect it from TWAINING at any time. Anything the assistant already received stays subject to that service’s own policies; disconnecting blocks future access. We never sell your data. Details in our Privacy Policy.
TWAINING is still in the works. Downloads and subscriptions open when we launch on the App Store. The plans shown here are the ones planned for launch.
Enough talk.
Your next program starts with a conversation.
