A personal trainer that builds your plan, checks your lifting form and adjusts your meals every week. Answer five questions and start your first session today.
Your gym has a coach now. GymBai builds the plan, watches your form, fixes your food and tells you when to rest — for the price of a protein shake, not a personal trainer.
Most fitness apps hand you a template and a timer. GymBai starts by asking your goal, your level, the equipment you actually have and how you like to eat, then generates a program around that. Every workout you log feeds back into the next one: weights go up when you are ready, sets get swapped when a joint complains, and a fatigue score built from your last 7 and 28 days of training load tells you whether today is a push day or a rest day.
WHAT YOU GET
• Walk into any gym with a plan that fits your equipment, your schedule and your goal
• Lift with confidence: the camera checks your squat, deadlift, bench, overhead press and row in real time, on your phone
• Know exactly what to eat: meal plans matched to your calorie and macro targets, plus photo and barcode logging when life is messy
• Stop guessing about recovery: a fatigue score and readiness check keep you from overtraining or slacking
• Watch progress that is real: weight trend, strength PRs, body measurements and side-by-side progress photos
• Get straight answers any time: a coach chat that already knows your plan, your logs and your last session
PERFECT FOR
• Beginners who want a program they can trust, not a wall of YouTube opinions
• Busy people who need a 20-minute session that still moves the needle
• Lifters coming back from a tweaked knee, shoulder or back who need safe alternatives, not a break
• Anyone tired of paying for a trainer just to be told what they could have logged in an app
WHY NOT JUST USE A SPREADSHEET AND A TIMER?
Because a spreadsheet does not notice that you missed two sessions, that your bench has stalled for three weeks, or that your knees cave on the way up. GymBai does, and it changes next week's plan for you. Rest timers, voice set logging and workout reminders are built in, so the phone stays in your pocket and the work gets done.
PRIVATE BY DEFAULT
No account, no sign-up, no social feed. Your workouts, meals, measurements and progress photos stay on your device. Form checks run entirely on-device: the camera never uploads video. Only what you choose to send — a coach question or a food photo you ask to have analyzed — leaves your phone, and only to produce that answer.
FULL ACCESS
