Mixed

The combination of high leisure time sitting (>=6 hours/day) and low physical activity (<24.5 MET-hours/week) is associated with a substantially higher risk of all-cause mortality compared to low sitting and high physical activity.

Your health risk is highest when you sit for 6+ hours a day AND exercise less than 24.5 MET-hours per week. To minimize this risk, aim to sit less than 3 hours a day and engage in at least 24.5 MET-hours of physical activity weekly. This dual approach offers the greatest protection against mortality.

Relative risks for sitting (>=6 hours/day) and physical activity (<24.5 metabolic equivalent (MET)-hours/week) combined were 1.94 (95% CI: 1.70, 2.20) for women and 1.48 (95% CI: 1.33, 1.65) for men, compared with those with the least time sitting and most activity.
