A rule-based engine, not a guess
Tell it your goal, experience level, how many days a week you can train, and what equipment your gym actually has. GymPlan filters its exercise database down to what you can really do, picks an appropriate split (Full Body, Upper/Lower, Push/Pull/Legs, or a glute-focused structure), and builds a day-by-day plan — then re-checks its own work, calculating weekly volume per muscle so you can see exactly why each exercise made the cut. It cites the training research its rules are based on, and it's upfront about what it isn't: a doctor, or "real AI."
