An oxygen debt.
Regular exercise strengthens your heart muscle by increasing its efficiency, allowing it to pump blood more effectively with each beat. It also improves circulation, which reduces strain on the heart. Additionally, exercise can lower blood pressure and cholesterol levels, further promoting heart health.
Oxygen Debt- A cumulative deficit of oxygen resulting from intense exercise; the deficit must be made up when the body returns to rest.
