Focus on the middle
That is, focus on your middle. Research in the Journal of the American College of Cardiology has linked excess belly fat to higher blood pressure and unhealthy blood lipid levels. If you’re carrying extra fat around your middle, it’s time to slim down. Eating fewer calories and exercising more can make a big difference.

Let the music move you
Whether you prefer a rumba beat or two-step tune, dancing makes for a great heart-healthy workout. Like other forms of aerobic exercise, it raises your heart rate and gets your lungs pumping. It also burns up to 200 calories or more per hour, reports the Mayo Clinic.

Go fish
Eating a diet rich in omega-3 fatty acids can also help ward off heart disease. Many fish, such as salmon, tuna, sardines, and herring, are rich sources of omega-3 fatty acids. Try to eat fish at least twice a week, suggests the AHA. If you’re concerned about mercury or other contaminants in fish, you may be happy to learn that its heart-healthy benefits tend to outweigh the risks for most people.

Move it, move it, move it
No matter how much you weigh, sitting for long periods of time could shorten your lifespan, warn researchers in the Archives of Internal Medicine and the American Heart AssociationTrusted Source. Couch potato and desk jockey lifestyles seem to have an unhealthy effect on blood fats and blood sugar. If you work at a desk, remember to take regular breaks to move around. Go for a stroll on your lunch break, and enjoy regular exercise in your leisure time.
