Activities Exceeding 4 METs
Activities exceeding 4 METs include brisk walking, running, swimming, bicycling, dancing, lifting weights, lawn mowing, and most sports participation—essentially any activity that falls into the moderate-to-vigorous intensity range (>3 METs) and specifically those in the upper moderate range (4-6 METs) or vigorous category (≥6 METs). 1
Understanding the MET Framework
According to the WHO 2020 Physical Activity Guidelines, the intensity classification system works as follows 1:
- Light intensity: 1.5-3 METs (slow walking, bathing)
- Moderate intensity: 3 to <6 METs
- Vigorous intensity: ≥6 METs
- Moderate-to-vigorous (MVPA): >3 METs
Since you're asking about activities exceeding 4 METs, you're looking at the upper range of moderate intensity and all vigorous activities.
Specific Examples by Category
Leisure Activities (>4 METs)
- Sports participation - most organized sports exceed 4 METs 1
- Running - clearly vigorous intensity 1
- Swimming - aerobic activity in vigorous range 2
- Bicycling - aerobic endurance activity 1
- Dancing - combines aerobic and balance components 1
- Exercise conditioning/training 1
Household/Garden Activities (>4 METs)
- Lawn mowing: 5.0-5.5 METs in older adults 3, 4
- Vigorous gardening 1
- Heavy cleaning tasks (context-dependent)
Resistance Training Activities (>4 METs)
Research demonstrates that common bodyweight exercises exceed 4 METs 5:
- Push-ups: 6.91 METs
- Lunges: 7.52 METs
- Pull-ups: 8.03 METs
Recreational/Gaming Activities (>4 METs)
Even exergaming can exceed 4 METs 6:
- Boxing games: 6.8 METs (vigorous)
- Soccer games: 6.2 METs (vigorous)
- Beach volleyball games: 5.7 METs
- Track and field games: 5.0 METs
Children's Activities (>4 METs)
Object projection skills in children 7:
- Kicking, throwing, striking at 30-second intervals: 4.5 METs
- Same activities at 12-second intervals: 6.3 METs
- Same activities at 6-second intervals: 8.3 METs (vigorous)
Important Clinical Caveats
Individual Variability Matters
While these are absolute MET values, the same activity can represent different relative intensities for different individuals 2. Walking at 3 mph (3 METs) is moderate intensity for a fit person but may be vigorous for someone with low cardiorespiratory fitness. Research shows that fixed MET ranges can misclassify physiological stress, particularly in heterogeneous populations 8.
Age-Specific Considerations
In older adults (≥60 years), conventional MET thresholds may not apply accurately 9. Fitness level significantly impacts whether an activity exceeds 4 METs—individuals with "good/superior" fitness had approximately 69% higher MET thresholds compared to those with "very poor/fair" fitness.
Context-Dependent Intensity
The same household activity performed at home versus in a laboratory setting can differ by 0.3-0.7 METs 3, 4. Self-paced activities show substantial inter-individual variability, meaning not everyone will exceed 4 METs doing the same task.
Practical Application
For clinical assessment purposes, when asking patients about activities exceeding 4 METs, focus on:
- Any activity causing noticeable increases in heart rate and breathing
- Activities in the upper moderate range (brisk walking, active housework/gardening)
- All vigorous activities (running, competitive sports, heavy resistance training)
- Activities where they can talk but not sing comfortably (moderate intensity marker)
The key distinction is that 4 METs sits firmly in the moderate-intensity range, so you're essentially asking about activities that require sustained effort beyond casual daily movement.
