The U.S. Department of Health and Human Services released the Physical Activity Guidelines, which state that adults should exercise at least 150 to 300 minutes per week at moderate-intensity, or 75 to 150 minutes a week at a vigorous-intensity. The guidelines also say that preferably, aerobic activity should be spread throughout the week. This means that you could perform a moderately intense jump rope session for 30 minutes 5 times per week and meet these guidelines.
