Ask ChatGPT for a training plan and you get something useful in seconds: weeks, days, exercises, sets and reps. Then you get to the gym and the plan is a wall of text in a chat. You scroll to find today, lose your place between sets, and log nothing.
The fix is to keep ChatGPT for what it's good at, writing and adjusting the plan, and move the plan into an app built for the gym floor.
The short version
- Connect ChatGPT to Athlyon once.
- Ask ChatGPT for a plan and tell it to save it to Athlyon.
- Open Athlyon at the gym and log each set as you go.
1. Connect ChatGPT to Athlyon
Athlyon connects to ChatGPT through the Model Context Protocol (MCP), an open standard that lets AI clients use tools from other apps. In Athlyon, open the menu, choose your AI client and follow the steps. For ChatGPT, they are:
- Open ChatGPT on the web, go to Settings → Connectors, and turn on Developer mode under Advanced.
- Create a connector named Athlyon and paste the server link Athlyon gives you.
- In a new chat, turn Athlyon on.
You do this once. After that, every plan ChatGPT saves shows up in the app.
2. Ask for the plan
Describe what you want the way you'd tell a coach: your goal, the days you can train, how long you have, your equipment and your experience. End with "save it to Athlyon." A good starting point:
Build me a 4-week strength plan. I can train Monday, Wednesday and Friday for about an hour, in a commercial gym. I have two years of lifting experience. Main goal: get stronger on squat, bench and deadlift. Split each day into Warm-up, Main block and Finisher, give sets, reps and rest for every exercise, and a short coaching cue under each one. Add a lighter deload in week 4. Save it to Athlyon.
ChatGPT builds the weeks, workout days, sections and exercises and sends them over. A few seconds later the plan is on your Home screen. For more on writing the prompt, see how to prompt an AI for a plan you'll actually follow.
3. Train from the app, not the chat
At the gym, pick the week and start the day's workout. Each exercise shows its sets with your previous numbers beside them, so you know what to beat. Log reps and weight as you go, or time and distance for conditioning work. Start the rest timer after each set; its length comes from the plan.
When you finish, rate how it felt and add a note. The summary keeps your time, sets and effort for every session.
4. Change the plan by asking
Plans meet real life. If the squat rack is always taken, you're travelling, or week 3 was too much, go back to ChatGPT and ask: "Swap back squats for hack squats in my Athlyon plan" or "Add a deload week." It updates the plan, and the app follows.
Why not just use the chat?
- Finding today's workout means scrolling. In Athlyon it's one tap.
- Logging in a chat is typing numbers into a text box. In Athlyon it's a field per set, with last session beside it.
- Your history in a chat gets lost between conversations. In Athlyon every session is saved with the plan.
