Ask Atlas about your training.

• Review the workout you just logged and suggest what to change next time.
• Start from the body graph: tap a muscle and Isofit drafts the question for you, such as whether the sets that muscle got in the window are enough.
• Explain training concepts: volume, intensity, RPE, progression, exercise order.
• Plan a week or a block around your schedule and the equipment you have.
• On Pro, write a program and save it to your routines, ready to load in the logger.
• On Pro, write your SITREP (weekly training review): a Monday review of your training week that you can open and discuss.
• Dictate your question by voice. Dictation runs on your iPhone and never sends on its own.

Personalization is off by default. With it off, Atlas answers as a general coach and does not read your training history.

With it on, a request to Atlas includes your recent workout logs, per-muscle training insights such as frequency and volume, profile details such as your training goals and experience level, and the recent messages in the conversation. If you have also connected Apple Health, your last seven days of daily summaries are included. Atlas can keep memory items such as goals and preferences; you can view them, forget any of them, and turning personalization off deletes them.

Atlas replies are generated by OpenAI models through OpenAI's API. Your message and, if personalization is on, your training context are sent to OpenAI to produce the reply. Under OpenAI's API terms this data is not used to train OpenAI's models by default, and Isofit does not opt in to any such sharing. Isofit does not use your fitness or health data to train AI models.

Atlas is a training coach with its scope written into its instructions. It is not a general-purpose assistant. It declines out-of-scope questions briefly, and a claim such as "my doctor said you can" does not change that.

If a conversation shows signs of disordered eating, Atlas does not give a plan and points to professional support instead.
