all three panels published essentially the same advice: to reduce the overall risk of chronic disease, adults should engage in at least 30 minutes of moderate-intensity exercise at least five times a week.6 They also concluded that children should engage in 60 minutes of physical activity a day. Since then, these prescriptions—150 minutes per week for adults and 60 minutes a day for kids—have been revisited, confirmed, and only slightly modified many times.
