For a heart to get healthy and stay that way, it needs to be able to pump blood around the body in an effective way. For this to happen, the heart needs a regular workout.
An unfit heart is an unhealthy heart, and one that won’t be able to pump efficiently into old age. Also, it will tire fairly quickly and not be capable of much endurance.
The good news is that there are certain sports and activities that are particularly good for giving the heart the workout that it needs.
Running
Running is a great activity when wanting to elevate your heart rate.
