Every section is a compact, self-contained card. Tap the link icon to share one section.

01

What AI can do for fitness

  • Build workout plans for your goals, time, and equipment
  • Explain exercises and suggest alternatives
  • Plan meals and grocery lists
  • Help track food, workouts, and progress
  • Keep you accountable with simple routines

AI can plan your training. Only you can show up.

02

What AI cannot do

  • It cannot see your form in person
  • It cannot diagnose injuries or medical conditions
  • It can give generic or wrong advice

Talk to a doctor before starting if you have health conditions, injuries, are pregnant, or are new to exercise.

03

Set a clear goal

I am [age], [height and weight], I train [days] a week for [minutes], with [equipment]. My goal is [goal] in [weeks]. I have [injuries or limits]. Ask me any questions you need first.

04

Build your workout plan

  • A weekly schedule with rest days
  • Exercises, sets, reps, and rest times
  • Warm-up and cool-down
  • Gradual progression week to week
  • Easier and harder options for each exercise
05

Adjust on the go

  • “I only have 20 minutes today.”
  • “I am travelling with no equipment this week.”
  • “My knee hurts on lunges. Give me alternatives.”
  • “I missed two workouts. How should I adjust?”

Stop any exercise that causes pain and get it checked.

06

Learn good form

  • Ask AI for step-by-step form cues
  • Watch videos from qualified coaches
  • Record yourself and compare
  • Consider a session with a qualified trainer
07

Nutrition and meals

  • Plan simple, balanced meals for your goal
  • Create grocery lists and prep plans
  • Ask for high-protein or budget options
  • See a registered dietitian for medical diets
08

Track food and progress

  • Photo-based calorie trackers can estimate meals quickly, but check their numbers
  • Track workouts in a simple log or app
  • Review progress every two to four weeks
  • Measure more than weight: strength, energy, sleep, and how clothes fit
09

Wearables and recovery

  • Use sleep and heart rate trends, not single readings
  • Ask AI to explain your data in plain language
  • Plan easier days when recovery is low
10

Build habits

  • Start smaller than you think
  • Schedule workouts like meetings
  • Ask AI for a weekly check-in routine
  • Focus on consistency over perfection
11

Stay safe

  • Avoid extreme diets or overtraining plans
  • Be careful sharing health data with apps
  • Check advice against trusted health sources
  • Get medical advice for pain, dizziness, or chest discomfort

The golden rule

Do not chase a perfect AI plan. Use AI to build a plan you can stick to, then show up consistently and adjust as you go.

  • Goal
  • Plan
  • Adjust
  • Form
  • Nutrition
  • Track
  • Safety

Ask AI for a four-week beginner plan that fits your week, and book your first three sessions.
