We all know that in order to develop strong muscles in our body, we need to exercise. But did you ever consider that your heart is also a muscle?

If the thought of lacing up and heading out the door for a heart-thumping run gives you panic attacks, no need to stress. Running isn’t for everyone, and there are lots of ways to make your heart strong that don’t involve running—although, that’s also a pretty great way to strengthen your ticker, too!
