Everyone knows that lifting weights can help build muscle. But might it also be good for your heart?

The answer is "yes," according to recent studies

Strength training may reduce body fat and blood pressure, and improve cholesterol and blood sugar control.

It can also help make everyday tasks like lifting groceries easier, with less stress on your heart.

Proper technique is essential to get the benefits and avoid injury.

Lift slowly, and don't hold your breath: exhale during exertion, and inhale during relaxation.

Try to work out two or three days a week. Alternate between upper and lower body exercises, and rest in between.

Before starting a program, it's a good idea to talk to your doctor, especially if you have heart disease.

And remember that strength training should not be a replacement for aerobic activities such as walking or biking, but an addition to them.

So a well-rounded exercise program that includes a little pumping may be the best one to keep your heart doing the same.
