Five to six sessions of varied cardiovascular intensity per week should include how many rest days?

• A. One full day
• B. Two days
• C. Zero days
• D. Four days

Answer: (A)

Rest and recovery are essential when training frequently. When you’re doing five to six cardiovascular sessions in a week with varied intensity, you need at least one full day for the body to recover, replenish glycogen, repair any small muscle damage, and let the heart rate settle. That single rest day helps prevent overtraining, reduces injury risk, and supports ongoing performance.

On a rest day you can keep things easy if you like—light walking, gentle mobility work, or stretching—so you stay active without stressing the system.

Zero rest days would push recovery aside, increasing fatigue and injury risk. Two rest days would reduce the number of training sessions below the target five to six per week, making it harder to reach that weekly training volume.
