Kernel density plots compare daily moderate-to-vigorous physical activity (MVPA) in minutes for weekend warriors (panel A) and regular exercisers (panel B), with orange indicating the remaining five days and blue indicating the top two days, showing greater variability between day types in weekend warriors and more consistency in regular exercisers. — Weekly MVPA distribution: top 2 days vs. remaining 5 days in active individuals (active: ≥231.5 min/week MVPA, sample median). MVPA distribution for active individuals (≥231.5 min/week, n = 47,067): 2 most active days (blue) vs. remaining 5 (yellow). (A) Weekend warriors (≥50% MVPA in 1–2 days). (B) Regular actives. Note: 147 weekend warriors (0.6%) with zero MVPA on 5 days assigned 1 min for log scale. MVPA indicates moderate to vigorous physical activity.
