Weekly activity calculator
Compare your recorded aerobic minutes and strength days with CDC weekly references.
Record one week. Enter 0 where no qualifying activity was recorded.
At this effort, you can talk, but not sing.
At this effort, you can say only a few words before pausing for breath.
Count each qualifying day once, not each session. Strength work should cover all major muscle groups.
Count each aerobic minute once. For golf, record qualifying activity time, not the whole round.
Enter your weekly totals, then select Calculate to see the comparison.
Calculate your weekly moderate-equivalent aerobic minutes from recorded moderate and vigorous activity. Then compare that total with the 150-minute reference and your distinct strength days with the two-day reference.
Use the tally to review your week, including qualifying golf activity, without turning it into a fitness grade or a personal exercise prescription.
Recorded moderate-equivalent aerobic minutes combine your moderate and vigorous minutes using the CDC two-to-one equivalence. This is a guideline tally, not elapsed exercise time.
The difference from the 150-minute reference shows how many moderate-equivalent minutes your recorded week is below that reference. The strength difference shows how many distinct strength days your week is below the two-day reference.
A zero difference means your recorded tally is at or above that reference. Differences never go below zero, so the calculator does not show how far you exceed a reference or assign a fitness grade.
The CDC states that one minute of vigorous-intensity activity is about the same as two minutes of moderate-intensity activity. Its weekly adult references include at least 150 moderate minutes, 75 vigorous minutes, or an equivalent combination, plus muscle-strengthening activity on at least two days.
Equivalent minutes = moderate minutes + 2 × vigorous minutes.
Minutes to 150 = max(0, 150 - equivalent minutes).
Strength days to 2 = max(0, 2 - strength days).
Here, max(0, ...) keeps each difference at zero once the recorded tally reaches the reference. Strength days are counted separately and are not added to aerobic minutes.
Enter whole minutes for one week and whole, distinct strength days. Each minute field accepts 0 to 10,080, but moderate plus vigorous minutes cannot exceed the 10,080 actual minutes in a seven-day week. Strength days must be between 0 and 7. Blank entries are not treated as zero.
Use the CDC intensity descriptions to classify your activity: - Moderate intensity: you can talk, but not sing, during the activity. - Vigorous intensity: you cannot say more than a few words without pausing for breath.
Do not put the same minute in both intensity fields. For golf, count only time that meets an intensity description, not the full length of the round.
Adults aged 65 or older also need balance activity. This calculator does not tally balance work or assign it a numerical target. The aerobic and strength references are public-health guidance, not a personal exercise prescription.
A week with 150 moderate minutes, 0 vigorous minutes and 2 distinct strength days produces:
Both differences are zero. The recorded week reaches both references, without establishing fitness or readiness for a round.
This is a self-reported weekly tally. Intensity estimates can be inaccurate, and the calculator cannot detect minutes entered in both intensity fields.
Meeting these references does not establish fitness, health status or readiness for 18 holes. The tool does not estimate calories, fatigue or recovery, and it does not prescribe a suitable activity level for someone with medical limitations.

Walking portions can count when they meet the moderate- or vigorous-intensity description. Do not automatically count the full round, including waiting, standing or riding in a cart. Record only qualifying activity minutes and count each minute once.
No. They are a guideline tally. Each vigorous minute contributes two moderate-equivalent minutes, but your actual exercise time has not doubled. Strength days are recorded separately and are not converted into aerobic minutes.
Use the CDC guidance for activity that works all major muscle groups and is challenging enough that another repetition would be difficult. The major groups include the legs, hips, back, abdomen, chest, shoulders and arms. Count a qualifying day once, even when you do more than one session that day.
