Claude is a strong programming partner. Give it your goal, schedule and history and it will write a sensible block with progression, deloads and coaching cues. What it can't do is stand next to you at the rack. That's what a workout log is for.
With Athlyon, the program Claude writes lands in an iPhone app as weeks, workouts and sets you can log.
Connect Claude once
Claude supports custom connectors through MCP. In Athlyon, open the menu, pick Claude and follow the steps:
- Open Claude and go to Settings → Connectors.
- Choose Add custom connector, name it Athlyon and paste the server link Athlyon gives you.
- In a chat, ask Claude to create a training plan in Athlyon.
What Claude sends over
A plan in Athlyon has a clear structure, and Claude fills all of it in:
- Weeks, each with workouts on set days.
- Sections inside each workout, such as Warm-up, Main block and Finisher.
- Exercises measured the right way: sets and reps (with or without weight), timed holds, work and rest intervals, or distance.
- Rest between sets and a short coaching cue under each exercise.
Logging the program
Open the day's workout and work through it. Each set shows what you did last time. Change the numbers when the day calls for more, and the log keeps what you actually did, not just what was planned. Intervals run on a full-screen timer that turns blue during work, so you can read it from across the room.
Finish the workout, rate the effort and leave a note. Notes on individual exercises, like a seat height or a cue that clicked, are saved too.
Keep the conversation going
The best part of programming with Claude is that it's a conversation. Ask it to swap an exercise, shorten a session, or adjust the next block, and the plan in Athlyon updates. You plan in the chat and train in the app.
