Section 1
AI is great at the boring parts
Most workout and nutrition advice online is the same 5 principles wrapped in different videos. AI is great at giving you a clean version of those principles applied to your body, your equipment, and your schedule. It's bad at the parts that need a real human — pain assessment, eating disorder screening, injury rehab.
Where AI is useful
- 1Building a 4-day-per-week training split based on your equipment and goals
- 2Calculating maintenance calories from a few inputs
- 3Suggesting exercise substitutions when your gym doesn't have something
- 4Building a grocery list from a meal plan
- 5Logging volume progression over time
Where AI is dangerous
AI doesn't know if you have a history of disordered eating, a knee injury, or a heart condition. It will cheerfully give you advice that's wrong for you. If you're under 18 and starting a serious training or nutrition plan, talk to a doctor first — AI is not a doctor and 'as an AI language model' is not a diagnosis.
Compare the options
| Use AI for | Don't use AI for |
|---|---|
| Workout structure on a normal week | Returning from an injury |
| Recipe ideas with macros | Restrictive diets if you've had ED history |
| Substitution when equipment is missing | Diagnosing why your knee hurts |
| Tracking progressive overload | Deciding whether to take a supplement |
| Hydration reminders | Hormonal or medication interactions |
Applied exercise: build a sane plan
- 1Tell AI your age, current activity, equipment, and ONE concrete goal (not 'get jacked' — 'do 5 pull-ups').
- 2Ask for a 4-week beginner plan.
- 3Cross-check the numbers against a reputable source (NHS, Mayo Clinic).
- 4Run the plan past a parent or coach for a sanity check.
- 5Track 2 weeks. Adjust based on what your BODY says, not just the spreadsheet.
Key terms in this lesson
The big idea: AI is a useful coach for the boring parts of fitness. It's a dangerous coach for anything involving pain, eating history, or pushing your limits — get a real human in the loop.
