Work out sedentary time risk instantly with clear inputs, formula shown and shareable results.
Sitting time carries health risk partly independent of exercise, and the risk climbs steeply beyond about six hours a day. Both structured activity and simply breaking up the sitting help: around 30-40 minutes of moderate activity substantially offsets long sitting, and frequent standing breaks improve glucose handling regardless of total exercise.
Excess sitting
excess = sitting hours - 6
Score
score = 8 points per excess hour, offset by activity and standing breaks
This is an estimate from population-average equations, not a medical or diagnostic assessment. Individual results vary with genetics, training history and technique. Seek advice from a qualified coach or clinician before making significant changes to training.
Partly. Studies find 30-40 minutes of daily moderate activity offsets much of the risk from long sitting, but frequent breaks matter separately.
Every 30 minutes ideally, even briefly. The frequency of breaks matters more than their length for glucose and lipid metabolism.
