About this app
9toFit is the fitness app for men who want to train seriously — with or without a personal coach.
What do you get with 9toFit?
★ Personalized training plan
Your coach builds a custom plan tailored to your goals, injuries, and available days. Or build your own plan with our smart Plan Builder.
★ Daily readiness check
How are you feeling today? Based on your sleep, muscle soreness, and energy level, the app adjusts your training with personalized advice.
★ Progress tracking
Track your weights, sets, and RPE per exercise. See exactly where you are making progress and where you are hitting a plateau.
★ Coach feedback directly in your workout
Your coach reviews your training data and provides feedback on specific exercises — visible during your next workout.
★ Habits and streaks
Build healthy routines with morning and evening routines. Track your streaks and build consistency. ★ Performance Score
A daily score based on sleep, recovery, habits, and training load. Know exactly where you stand.
★ Weekly Snapshot
Weekly overview of your training, habits, and progress compared to previous weeks.
Who is 9toFit for?
