Workout tracking to see your strength gains over time.
One Fitness Hub is a workout tracker for beginners and experienced lifters who want to see what changed between sessions. Record weight, reps, failures and gear notes, then use exercise history, estimated one-rep max and training volume to follow your fitness progress.
How to get started
Choose an exercise
Open the + button and choose Add exercise. Pick a recent lift or search the full library. Your recent exercises appear first, and previous results help you decide what to log today.
Record each set
Enter the weight and reps, mark a failure when relevant, and add gear notes. Estimated one-rep max and volume update as you log, and new personal records are flagged on the set.
Look back before your next session
Open Exercise History to find the lift and review earlier sessions. Compare weight, reps and volume; use desktop analytics for longer trend lines.
Everything a set needs, nothing it doesn't.
Weight and reps, fast
Enter a set in two taps. Last time's numbers for that exercise are shown right above the input, so you always know what you're trying to beat.
Estimated one-rep max
Calculated automatically from your weight and reps on the working set, and shown per exercise so you can track it over time without doing the math yourself.
Volume, tracked as you go
Running total for the session and for the exercise, so a change in your training is visible immediately, not just in hindsight.
Failures and gear, logged honestly
Mark a set as a failure and note whether you used a belt or straps. Both feed into how a lift is reviewed if you ever submit it to a leaderboard.
Your library, sorted by what you actually do.
The exercise picker opens on what you've logged recently, newest first, so the lift you're about to do again is already at the top. Search the full library any time you need something new.
- PRs flagged the session you set them, on the set itself

Common questions
How can I track strength gains between workouts?
Record the same exercise consistently, then compare weight, reps, estimated one-rep max and volume in your history. A heavier set or more reps at the same weight can show progress even between personal records.
Do I need to build a routine before logging?
No. You can choose an exercise and log your first set directly. Your recent exercises make it easier to find that lift next time.
Is estimated one-rep max the same as a tested maximum?
No. Estimated one-rep max is calculated from the weight and reps you log. It is a fitness estimate for following trends, not a measured maximum or a guarantee that you can lift that weight.
Can I track food alongside my workouts?
Yes. The same account includes food and nutrition tracking. Logged workouts add estimated active calories to the day's nutrition budget.
