Yes, as you improve your fitness, your resting heart rate generally becomes lower. Regular exercise, especially cardiovascular activities such as running or swimming, can strengthen the heart muscle and improve its efficiency, allowing it to pump more blood with fewer beats. This can lead to a decrease in resting heart rate. Additionally, as your cardiovascular fitness improves, your body becomes more efficient at delivering oxygen and nutrients to the muscles, reducing the need for the heart to work as hard during rest.
