Question

which statement is true about regular exercise?
a. it increases your blood pressure.
b. it decreases your resting heart rate.
c. it increases your intelligence.
d. it decreases your lung capacity.

Explanation:

Regular exercise strengthens the heart muscle, allowing it to pump more blood with each beat. This efficiency leads to a lower resting heart rate. Blood pressure is typically reduced (not increased) with regular exercise. Lung capacity is increased (not decreased). There's no direct evidence that regular exercise increases intelligence.

Answer:

B. It decreases your resting heart rate.
