Understanding the workout logger
Store workout details locally and summarize sessions and minutes logged during the last seven days.
This page provides an equation-based estimate for education and planning. It does not diagnose a condition, measure an individual response, or replace professional care.
How to use this health calculator
- Choose appropriate inputs: Enter measurements using the units and ranges shown.
- Review the assumptions: Confirm that the model applies before interpreting the result.
- Calculate and interpret: Read the result together with its limitations and cautions.
- Use professional guidance when needed: Do not use a general calculator to change medication, treatment, or a clinician-directed plan.
Formula and variables
The output follows the stated arithmetic and assumptions; it is not an individualized diagnosis, prognosis, or treatment recommendation.
Weekly minutes = sum of durations for entries dated within the rolling seven-day window.- D — Duration
- Logged workout minutes.
Worked example
Three workouts of 30, 45, and 20 minutes fall within seven days.
- Durations
- 30, 45, 20 minutes
- 30 + 45 + 20 = 95 minutes.
Result: Three workouts and 95 total minutes are logged.
Interpret the result with its population, measurement, and clinical limitations.
