Best AI for building a workout plan
Most AI workout plans look right and are subtly wrong — wrong rep ranges for the goal, wrong exercise order, no progression scheme. The right model knows the difference between a strength program and a hypertrophy program. The wrong one gives you 5x10 of everything.
Most willing to ask clarifying questions (experience level, equipment, frequency) before producing a plan — and the plans actually reflect modern programming principles.
GPT-5.4 is stronger at producing structured, week-by-week progression schemes ready to drop into a spreadsheet.
Build me a 4-day-a-week hypertrophy program. Intermediate lifter, full barbell + dumbbell + cable access, 60-min sessions, 8-week mesocycle. Include progression scheme (sets/reps/weight per week) and one alternate exercise per movement.
What to look for in any model
- 1Specify: experience level, days/week, equipment, primary goal (strength/hypertrophy/conditioning)
- 2Ask for the PROGRESSION scheme, not just one week — without progression it's a workout, not a program
- 3Both models occasionally invent exercises — verify anything that sounds unfamiliar before you load weight
- 4For injury history or rehab work, see a physical therapist — AI is not a substitute
