TheFitness

Workout AI is your personal fitness coach — powered by an on-device AI model that works entirely offline.
ON-DEVICE AI COACH
Chat with your personal fitness coach, a local AI model that runs right on your phone. Ask it to design a workout, get form advice, or adjust your routine — no internet connection needed. Your conversations never leave your device. The coach automatically builds structured workout plans from your natural-language requests: just say "30-minute leg day, easy on knees" and get a ready-to-go plan with video demos.
700+ EXERCISE VIDEO DEMOS
Browse a built-in library of over 700 exercises across 8 categories — Chest, Back, Legs, Shoulders, Arms, Core, Cardio, and Mobility. Every exercise includes a looping video demo so you can see proper form instantly. No guessing, no YouTube searching.
SMART WORKOUT BUILDER
Tell the AI your focus areas, available equipment, time limit, and goals. It generates a complete workout with exercises, sets, reps, rest times, and notes — all matched to your exercise video library. Prefer to build manually? Pick exercises one by one from the full catalog.
EQUIPMENT-AWARE FILTERING
Select your setup — Free Weights, Bench, Smith Machine, Resistance Bands, Bodyweight, Mat, or Mobility/Stretch — and the app filters exercises to match your environment. No more discovering mid-workout that you need equipment you don't have.
WORKOUT TRACKING
Log every set with weight and reps as you train. The app remembers your previous performances and shows ghost text hints — your last weight and reps appear as placeholders so you know what to beat. Cardio exercises support duration and distance logging too.
PROGRESS & HISTORY
Review your complete workout history with date, duration, and volume breakdowns. See category volume stats at a glance. Track your progress over time with visual charts showing how your weights have improved.
SAVE & REPEAT
Save any workout as a custom plan or favorite exercise list. Repeat your last workout with one tap. Build a library of go-to routines you can start instantly.
FULLY OFFLINE
Everything works without an internet connection. The AI model, exercise videos, workout tracking, and history all live on your device. Train in the gym, at home, or on the road — no Wi-Fi required.
DATA BACKUP & EXPORT
Export all your workout data as a JSON backup file and import it anytime. Your data stays under your control.
DARK MODE & ACCESSIBILITY
Automatic light and dark theme support. Haptic feedback for key interactions. Built with accessibility roles and labels.
NO SUBSCRIPTION, NO ACCOUNT
No sign-up. No monthly fee. No cloud dependency. Your data, your device, your workout.
