GYMKC - AI Gym Workout Coach
Your AI trainer for every set
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
The day your personal training ends, no one tracks your progress.
GYMKC fills that gap. Pick a goal, muscle growth or strength, and it prescribes the exercises that fit, pushes each set close to your limit, and carries every result into your next workout. Your equipment and injuries are part of the math.
The moment you log a set, your next set is recalculated, and the AI trainer explains why from your records.
GYMKC is not a medical device and does not diagnose, treat, or prevent any disease. If you have pain or a health condition, consult a medical professional before exercising.
WHY GYMKC
• Not just a chatbot: your next weight comes from a calculation engine, so the same records give the same prescription.
• Built on your records, not general advice: last week's weights, reps you had left, and the rest you actually took.
• Weekly volume per muscle stays within what you can recover from, and stalled lifts get flagged.
• Rest adapts in real time to how hard your last set was.
COACHING ON EVERY SET
• Log a set and get the next weight, reps, and rest right away.
• Remaining volume adjusts to how you feel; the weight goes up when you beat your target.
• Stalled lifts get a cause check and variation swaps.
• Short on time? "Short" keeps the essentials, and a session time goal trims long days.
• Machine taken? Swap to a substitute instantly.
• AI trainer chat answers from your actual records and can update your routine.
LEFT-RIGHT BALANCE
• For dumbbell-style exercises, it asks which side felt harder and adds check sets when signals build up. It never lowers your weight on its own.
CREWS
• One invite code for coaches, clients, or friends: weekly challenges, shared workouts and routines, rankings, and pinned coach reviews.
PROGRESS AT A GLANCE
• Max weights and trends, weekly volume per muscle, a workout calendar, personal records, weekly reports, and muscle recovery.
• Body weight, body composition, and progress photos. Photos stay on your device.
AI PHOTO RECOGNITION
• Snap an unfamiliar machine to learn what it is and how to use it.
• Snap your current routine (screenshot, spreadsheet, or handwritten notes) to copy it over (Pro).
BUILT FOR THE GYM FLOOR
• 7,630 exercises with 3D form demos and muscle maps.
• Routines built only from the equipment you register. Kg or lb.
• "Anywhere session" for equipment-free workouts on the road.
• Form self-check: film yourself next to the 3D demo. Videos stay on this device.
• Rest alerts, reminders, and a shareable workout card.
APPLE WATCH
• Complete sets, adjust reps and rest, rate effort, and answer trainer suggestions from your wrist.
• Timed holds, interval taps, and heart rate for better calorie tracking.
• Outdoor running, walking, and cycling with GPS. Location is used only on the device, never stored or sent to a server.
PRICING
Everything you do yourself is free. What the trainer does for you is Pro.
