What are MET-minutes and why do they matter?

MET (Metabolic Equivalent of Task) is a standard measure of exercise intensity. Walking = ~3.5 METs, brisk walk = ~4 METs, running = ~8 METs. MET-minutes = METs × minutes. The CDC recommends 500–1000 MET-min/week for substantial health benefit. This unit lets you compare different exercise types on a common scale.

Does vigorous exercise count double?

Yes. The CDC considers 1 minute of vigorous activity equivalent to 2 minutes of moderate activity. This is why 75 minutes of vigorous activity per week meets the same guideline as 150 minutes of moderate activity.

Can daily steps replace structured exercise?

Steps capture NEAT (non-exercise activity thermogenesis) but not exercise intensity. 10,000 steps at a slow pace (~3 METs) generates about 350 MET-min/day — beneficial, but does not fully replace the cardiovascular and musculoskeletal benefits of structured aerobic and strength training.

Why is flexibility/mobility included?

Flexibility and mobility work reduce injury risk, improve posture, and support long-term functional independence — especially important as exercise volume increases with age. The CDC includes flexibility in comprehensive physical activity guidelines.

Is it possible to exercise too much?

For most people, especially those below CDC minimums, more activity is better. Overtraining risks apply mainly to competitive athletes. The calculator scores based on health-optimal activity levels, not performance levels.

What Is My Daily Activity Score?

Are you meeting your daily movement targets?

What This Does

Physical activity is measured in multiple dimensions that step counts alone can't capture: aerobic intensity, strength training frequency, flexibility work, and how sedentary time is broken up throughout the day. The CDC recommends 150 minutes of moderate aerobic activity per week, 2+ days of strength training, and movement throughout the day — yet most activity trackers reduce all of this to a single step count. The Daily Activity Score Calculator gives you a comprehensive 0–100 score across five activity zones: step count, aerobic/cardio activity, strength training, standing time, and flexibility/mobility. It translates your inputs into MET-minutes per week — the standardized measure used in exercise science research — and estimates your weekly caloric expenditure from activity. More importantly, the calculator checks your inputs against CDC and WHO guidelines, flags gaps between your current activity and evidence-based targets, and shows you which changes would give you the largest score improvement with the least effort. Whether you're trying to meet CDC minimums for the first time, optimize an already active lifestyle, or understand the impact of a desk job on your health, this tool gives you a decision-ready activity picture.

Assumptions

·MET values are standard averages; actual energy expenditure varies by fitness level and body weight
·Calorie estimates use 1.3 kcal/MET-min for an average adult; individual results vary
·CDC guidelines are used as scoring benchmarks (150 min moderate or 75 min vigorous per week)
·Step-to-MET conversion assumes average walking speed (~3.5 MET)

When Should You Use This?

→You want to know if your current activity level meets CDC guidelines
→You're converting your weekly exercise to MET-minutes for research or tracking
→You're trying to understand how sedentary time interacts with exercise
→You're building a structured fitness plan and want to measure baseline activity
→You want to estimate calories burned from activity (not total TDEE)
→You're recovering from injury and want to understand your current functional activity level

Example Scenario

Kevin, 31, walks about 7,500 steps daily, does 2 gym sessions per week (45 min each), and goes for one 30-min run per week. He sits 8 hours at his desk job with 3 walk breaks per day. He scores 62/100 — Active. His total is 680 MET-min/week, well above the CDC 600 MET-min minimum. His calculator flags that his flexibility work is zero and he's below the CDC "optimal" of 300 aerobic minutes per week. Adding two 20-min yoga sessions and replacing one commute day with an e-bike ride would push him to 78/100 — Highly Active.

Common Mistakes to Avoid

✕Counting only gym sessions and ignoring incidental movement (NEAT) — both matter for metabolic health
✕Forgetting to include active commuting, sport, or recreational activities in exercise minutes
✕Assuming exercise time replaces prolonged sitting — they have independent effects on metabolic health
✕Skipping strength training — especially important for metabolic health and after age 35 for muscle mass preservation
