Fitbod builds your workout to match the duration you set in your My Plan setting, adjusting how many exercises it includes. A four-exercise workout typically takes 27 to 51 minutes, five exercises 35 to 60 minutes, and six exercises 39 to 63 minutes. A one-hour workout usually contains around seven exercises. Actual time varies with your pace, rest periods and gym setup.

Setting a duration that matches your life
Key takeaways
- Fitbod changes the number of exercises, not the workout structure, when you adjust your duration setting.
- Estimated ranges: 4 exercises → 27–51 minutes, 5 exercises → 35–60 minutes, 6 exercises → 39–63 minutes. These cover more than half of all workouts logged.
- Around 5% of Fitbod members finish five-exercise workouts in 21 minutes or less, and four-exercise workouts in 15 minutes or less.
- Rest periods are the most common reason a workout finishes faster than expected.
- You can extend a session by raising your duration setting, adding exercises or sets manually, or taking the recommended rest.
How Fitbod estimates workout length
When you set a workout duration, Fitbod selects a number of main exercises expected to fill that time. The estimate accounts for the sets in each exercise and the recommended rest between them.
Because pace varies so much between people, Fitbod publishes ranges rather than fixed times:
| Main exercises | Typical completion time |
| 4 | 27–51 minutes |
| 5 | 35–60 minutes |
| 6 | 39–63 minutes |
These ranges cover more than half of all logged workouts. A one-hour session generally works out to about seven exercises.
Your actual time will land somewhere in these ranges, or outside them, depending on how you train.
Why your workout might feel shorter than expected
Finishing early is common and usually comes down to one of four things:
Rest periods: this is the biggest factor. Fitbod's estimate assumes you take the recommended rest between sets. Cutting rest short compresses the whole session.
Gym setup: having your equipment within reach removes transition time between exercises. A home setup or a quiet gym floor moves faster than a busy one.
Fewer distractions: not checking your phone, taking water breaks, or talking between sets adds up across a full session.
Timed intervals and supersets: these formats deliberately minimize rest, so they naturally reduce total workout time.
For context on how much this varies: about 5% of Fitbod members complete five-exercise workouts in 21 minutes or less, and four-exercise workouts in 15 minutes or less. Pacing differs considerably from person to person, and finishing faster than the estimate doesn't mean anything went wrong.
How to make your workouts longer
If your sessions consistently end sooner than you want:
- Increase your workout duration setting: this is the most direct fix. Fitbod will generate more exercises to fill the longer window. You can change it in your My Plan.
- Add exercises or sets manually: if you finish early on a given day, you can extend that workout without changing your overall setting.
- Follow the recommended rest times: if you've been cutting rest to save time, taking the suggested breaks will bring your sessions closer to the estimate, and rest between sets is part of how the training works.
How to make your workouts shorter
Lower your duration setting in your My Plan and Fitbod will build shorter sessions with fewer main exercises. Fitbod continues to balance muscle groups at shorter durations rather than simply removing exercises from the end.
Supersets and circuits are also worth considering if your goal is to train in less time. They reduce rest between movements rather than reducing the work itself.
A note on ongoing changes
Fitbod continuously analyzes workout data and refines its workout algorithm, so these estimates may shift over time as the models are updated.
Frequently Asked Questions (FAQ)
Does changing my duration change the number of sets, or just the exercises?
It changes the number of main exercises. A shorter setting produces fewer exercises, a longer one produces more. If you want more volume within a session you've already started, adding sets manually is the way to do it.
Why did my workout take longer than the estimate?
The ranges above cover more than half of all logged workouts, which means a meaningful share fall outside them in both directions. Longer sessions usually come down to the reverse of the factors that shorten them: taking more rest than recommended, waiting for equipment in a busy gym, or breaking between sets. None of that is a problem, but if it happens consistently, lowering your duration setting will bring the estimate closer to reality.
Will a shorter workout still be worth doing?
Fitbod applies the same logic at every duration. Your goal, equipment and current muscle recovery still shape which exercises you get, so a shorter session is a smaller version of the same programming rather than a lesser one. Supersets and circuits are worth considering too, since they shorten a session by reducing rest rather than by reducing the work.
Setting a duration that matches your life
The duration setting works best when it reflects how long you actually train, not how long you intend to. If you're consistently finishing early, that's useful information: lower the setting so the estimate matches, or keep it where it is and add sets when you have time. Either is better than a setting you rarely meet, because Fitbod builds every workout against the number you've given it.
