Train your way. Keep every workout.
Your Fitness Diary
Use FitnX to record strength workouts, cardio, runs, rides and more. Start right away, add exercises as you go, or use a saved Plan.
Choose how you want to start
Start the workout that fits your day.
Begin with a blank workout, record one activity, or follow a Plan you saved earlier.
Build as you go
Start with a blank workout. Add and finish one exercise at a time. Save the workout as a Plan if you want to use it again.
One activity
Record one activity without building a full workout. Use it for a run, ride, walk, cardio machine, timed activity or one strength exercise.
Use a Plan
Prepare a workout before you start. Put exercises in order, choose the number of sets, and use the same Plan again later.
The right details for every exercise
Choose how to record your results.
FitnX can use results you enter, values calculated from a machine, or supported data from your phone and watch.
Enter it yourself
Type in details such as weight, reps, time or distance.
Use machine settings
Enter speed, resistance, incline or other settings. FitnX calculates supported results from the settings and your time.
Track with your device
Let your phone or watch record supported details such as your route, distance, pace, elevation, heart rate and active calories.
Plan ahead or change it later
Build a workout you can use again.
Create Plans with normal sets, warm-up sets, drop sets and supersets. Put exercises in order, repeat sets and add rest goals.
You can still make changes after the workout starts. Fix a result, replace an exercise, change the next set or rest time, and add more exercises without stopping.
Set up exercises your way
Make each exercise match how you do it.
If an exercise is missing, create your own. Choose what you want to record and, for strength exercises, which muscles it works.
Use variations for a different grip, stance or technique. Use configurations for different equipment or settings. FitnX then compares results from the same setup.
Routes and laps
See where you went and how each lap went.
Open a tracked activity on the map to see its route, distance, time, pace, speed and elevation. Add laps while you train, or let Pro add them automatically.
The full route is available to everyone. With Pro, choose a lap to highlight it and see its own results. For indoor machines, use sections when the settings change.
FitnX on your watch
Keep your workout on your wrist.
Start a supported activity on your phone and use your paired watch to record available data such as heart rate, active calories and distance.
With Pro, start saved Plans or supported exercises directly from Apple Watch or Wear OS. You can always keep training on the phone when the watch is not available.
Your progress
See what you did and how you are improving.
FitnX turns your finished activities into clear statistics. See recent workouts, weekly activity, training load, time, muscle groups, outdoor distance, exercise progress and body measurements.
Open any result to see the workouts behind it. Compare workouts from the same Plan or follow one exercise and setup over time.
Works without internet
Keep training when you are offline.
Open your saved diary, record your workout and review downloaded history without a connection. FitnX syncs your changes when you are online again.
No signal? You can still train.
