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?

So something you may be missing…. is that it DOES hurt your heart.
It puts stress on your heart, just like any muscle, and too much could damage it.
But just like any other muscle, stressing it for some amount of time, and then resting, will cause it to strengthen, just like any other muscle.
If you have a heart condition, or your heart is already damaged, then raising it may not be recommended.
