Frequency measures how often you do physical activity within a set period—the number of times you start or complete an activity bout. This focus on the number of occasions over time is what distinguishes frequency from the others: duration looks at how long you’re active in total, intensity describes how hard you work, and the type describes what activity you’re doing. For example, two 15-minute walks in a day have higher frequency than a single 30-minute walk, even if the total time is the same. Frequency is often tracked as bouts per week to align with guidelines.
