Your AI personal trainer that plans your workouts, sets your loads and drives your progress — for a fraction of the price. Workouts, plans and stats, all in one place.
Grynd isn't just another rep counter. It's an intelligent training coach in your pocket — it knows your goals, plans your workouts and guides you toward the body you've always wanted. You train. Grynd thinks for you.
Most training apps only log sets and reps — you have to figure out the rest yourself. Grynd works completely differently. Advanced AI-powered systems analyze your workouts, adjust your loads and build your plans — just like a real personal trainer would.
AN AI COACH THAT LEADS THE WAY
You just train — start a session and check off your sets. Grynd handles the rest: it plans your workouts right in your calendar, picks the right weights for your level and continuously adapts your plan to your progress and fatigue. This isn't a tip generator — it's a coach that genuinely drives your development and gets to know you better with every workout.
AI coach features are available with a premium subscription.
FULL CONTROL DURING YOUR WORKOUT
Run your session live and log sets, reps and weights in seconds. Use different set types, combine exercises into supersets and set rest timers. Your data is safe — even restarting your phone won't interrupt your workout.
YOUR PLANS, YOUR RULES
Create your own training plans and start them with a single tap. Build a weekly schedule and browse a constantly growing exercise database — and if something's missing, add your own exercise.
PROGRESS YOU CAN SEE
Grynd automatically detects your personal records and shows your progression on clear charts — strength, training volume and results over time. Log your body measurements and watch your body change.
ALWAYS WITHIN REACH
Check your training calendar — what's done and what's planned. Control your workout straight from the lock screen with Live Activity. Choose light or dark mode. The app is fully available in English and Polish.
GRYND PREMIUM
Features such as workout tracking, creating routines and exercises, and viewing statistics are free. A premium subscription adds an intelligent AI coach that runs the app and drives your entire development.
Download Grynd and train smarter — with a coach who knows you better every day.
