Purpose: To investigate in a real-life setting how moderate and vigorous intensity physical activity (PA) volumes differ according to absolute intensity recommendation and relative to individual fitness level by sex, age, and body mass index (BMI). Methods: 23 224 Finnish employees (10 201 men, 13 023 women; ages 18-65 years; BMI 18.5-40.0 kg/m2) participated in heart rate recording for 2+ days. We used heart rate and its variability, respiration rate, and on/off response information from R-R interval data calibrated by participant characteristics to objectively determine daily PA volume, as follows: daily minutes of absolute moderate (3-=6 METs) PA; and minutes relative to individual aerobic fitness for moderate (40-=60%) PA. Results: According to absolute intensity categorization, the volume of both moderate and vigorous PA was higher in men compared to women (P
