  1. Step 1

    Tell your AI what fits

    Your goal, the days you can train, the equipment you have. ChatGPT or Claude builds a plan around your answers.

  2. Step 2

    Take it to the gym

    Save the plan to Simple Muscle. Follow it on iPhone and log the sets, reps, and weights you complete.

  3. Step 3

    Adjust as life changes

    Ask your AI to review your workouts or adapt next week. It can use your logged training instead of asking you to recap it.

Questions

AI workout planner FAQ

What is an AI workout planner?
An AI workout planner turns your goals, experience, schedule, and equipment into a training plan. With Simple Muscle, ChatGPT or Claude can also save that plan and review your logged workouts when you ask for an adjustment.
How is this different from a workout generator?
A generator gives you a starting plan. Simple Muscle connects your AI to the workouts you save and complete, so you can keep working on the same plan as your schedule and training change. Try our free generator if you want a plan before creating an account.
Can I use ChatGPT or Claude?
Yes. Connect Simple Muscle to the assistant you use, then ask it to create or update your plan. You choose your AI; Simple Muscle keeps your workouts and training history.
What does it cost?
The web account and AI connection are free. Local iPhone tracking is also free. Syncing between iPhone and your account is free for seven days, then $5 a month or $50 a year. Your AI provider may have its own plan requirements.
Can my AI change workouts I already completed?
No. It can review your completed sessions and help update future workouts. Your logged history stays unchanged. Review any proposed plan before saving, and get qualified guidance for injuries or medical conditions.
