What is the recommended duration for each cardiovascular workout session?

• A. Time
• B. Frequency
• C. Type
• D. Intensity

Answer: (A)

Time is the measure of how long you perform cardio in a single session. This directly answers the question about duration, since duration refers to the length of each workout. The other aspects—frequency, which is how often you train; type, which activity you choose; and intensity, which how hard you work—describe different parts of the plan, not the length of one session. So for guidance on how long each cardio workout should last, the focus is on time. (If you’re aiming for a weekly total, that can guide how you distribute those minutes across sessions, but the per-session duration remains the time.)
