Hello,
When I do cardio my heart rate climbs twice to about 150-160bpm. People say that it’s actually good for your health and well being of heart. How does making the heart work twice as fast help it instead of hurting it?

Because your heart is a muscle, and what you’re doing is working it out. A healthy heart benefits from exercise the same way your arms and legs do. Working out *does* put extra strain on it, but if you do it regularly in a safe way, it’ll get used to it and become stronger overall and have an easier time working at whatever rate it’s currently beating.
