Analyze strength-session density from working sets, reps, rest periods, transitions and session duration to show how tightly packed the workout is.
Use average values. The analyzer estimates time from work + rest + transitions; it does not measure your real stopwatch data.
Session density describes how much training work is packed into a given amount of time. It is affected by set count, rest periods, exercise transitions and the actual work time of each set. A session with fewer sets but very short rests can be dense; a session with many sets and long rests can be longer but less dense.
Users often compare sessions by total minutes without checking what created the time. The analyzer separates work, rest and transitions so you can see which component is consuming the session window.
If the estimated session exceeds your target window, the output tells you that the structure does not currently fit. That does not mean you must rush rest periods. You can reduce sets, use fewer transitions, shorten accessories or move work to another session.
Large compound movements may need longer rests, while some accessories can be organized with shorter transitions. The tool makes no judgment about which rest period is appropriate; it shows what your chosen timing implies for the clock.
Timing is estimated. Rep speed, equipment availability, setup, plate changes, conversation, warm-ups and unexpected delays are not fully represented. Use the result as a planning estimate rather than a stopwatch replacement.
It is a description of how much work is performed relative to the time used.
Not automatically. Density is a structural characteristic, not a quality score.
No. It uses your average work, rest and transition inputs to estimate total time.
You can approximate it by entering the average transition and rest structure, though circuits may require more specialized timing rules.
The tool does not tell you to do so. It shows the time effect of the rest intervals you choose.
Yes. Enter 45 as the target session window and adjust the exercise rows until the estimate fits.
