Answer 1

Answer: The answer is C.
Explanation: Your heart is like one muscle and by having a healthy diet and regular physical activity your heart gets strong but like all muscles once you get used to doing a certain exercise you don’t get stronger and so you must increase your time and reps of whatever you’re doing.
