| Weekly moderate activity |
Adults should complete at least 150 minutes of moderate-intensity aerobic activity per week; WHO identifies 150–300 minutes as the recommended range. |
Clothing may be worn repeatedly for walking, commuting, errands, and other regular movement, so comfort must remain consistent over time. |
No persistent rubbing, pressure points, or restriction during repeated low-to-moderate activity. |
| Vigorous-intensity equivalent |
Adults can alternatively complete 75–150 minutes of vigorous-intensity aerobic activity per week, or an equivalent combination of moderate and vigorous activity. |
Higher exertion can increase heat, sweat, and movement forces, making breathability, secure fit, and freedom of motion more important. |
The garment stays in place and does not become excessively hot, heavy, or restrictive as intensity rises. |
| Muscle-strengthening activity |
WHO recommends muscle-strengthening activities involving major muscle groups on 2 or more days per week for adults. |
Squats, lifting, carrying, and floor-based movements require fabric and seams that accommodate bending, reaching, and changing body positions. |
Full movement is possible without seam strain, waistband rolling, or fabric pulling across joints. |
| Activity intensity |
WHO describes moderate activity as approximately 3.0–5.9 METs and vigorous activity as 6.0 METs or more. |
Different intensity levels create different demands for stretch, ventilation, moisture management, and garment stability. |
The same garment remains wearable across light daily movement and more demanding sessions. |
| Sedentary-time reduction |
WHO recommends limiting sedentary time and replacing it with physical activity of any intensity, including light-intensity movement. |
Everyday activewear should be comfortable not only during exercise, but also while standing, walking, traveling, and completing household tasks. |
Comfort is maintained during prolonged sitting, standing, and frequent transitions between positions. |
| Thermal comfort |
Physical activity increases metabolic heat production; higher-intensity activity generally increases the need for heat dissipation and sweat management. |
Breathable construction and effective moisture movement can help reduce clamminess and discomfort during active use. |
The fabric does not remain excessively wet, cling uncomfortably, or trap heat during movement. |
| Fit and pressure |
There is no single universal clothing pressure value for all bodies or activities; comfort depends on fit, fabric stretch, garment construction, and personal sensitivity. |
A balanced fit supports movement without creating unnecessary compression, slipping, or pressure at the waist, shoulders, thighs, or underarms. |
The garment feels secure but not tight, and remains stable during walking, bending, and reaching. |
| Skin and seam comfort |
Repeated movement and moisture can increase the likelihood of friction-related irritation, especially in areas where fabric, seams, and skin repeatedly contact. |
Smooth seam placement, suitable construction, and a comfortable hand feel can support longer wear and more frequent activity. |
No noticeable chafing, scratchiness, seam digging, or irritation during or after activity. |
| Mobility and range of motion |
Movement patterns such as walking, climbing stairs, squatting, reaching, and sitting involve repeated changes in joint angles and body position. |
Adequate stretch and thoughtful pattern design help clothing follow the body instead of resisting ordinary movement. |
The wearer can walk, sit, squat, reach, and climb stairs without fabric restriction. |
| Wear frequency and durability |
Meeting the WHO weekly target may involve activity distributed across multiple days, creating repeated cycles of wear, washing, drying, and movement. |
Durable construction and retained shape support reliable comfort across regular use rather than only during the first wear. |
The garment maintains fit, stretch, and surface comfort after repeated normal care and use. |
