_______ are exercises that strengthen the heart and lungs and last at least 10 minutes.

Aerobic exercises are specifically designed to enhance cardiovascular endurance and strengthen the heart and lungs. These activities typically require sustained effort over a period of time, generally lasting at least 10 minutes, which allows for improved oxygen uptake and increased heart rate. This type of exercise includes activities such as running, cycling, swimming, and dancing, where the body uses oxygen efficiently to fuel prolonged physical activity.

In contrast, anaerobic exercises, which are not the correct choice, focus on short bursts of activity, such as sprinting or weightlifting, where the body relies on energy sources that do not require oxygen. Atrophy refers to the decrease in muscle mass due to inactivity or lack of use and does not relate to exercise types. Additionally, blood pressure is a medical measurement related to the force of blood against artery walls and does not pertain to exercise classifications. Hence, the term that accurately describes exercises aimed at strengthening the cardiovascular system over an extended duration is aerobic.
