Strengthening your heart is one of the best things you can do for your health. And as you know, the best way to strengthen your heart is to exercise. In fact, if you don’t exercise you’re more than twice as likely to get heart disease as someone who does. If you have a history of heart disease, or just worry about your heart health, you need to develop a regular exercise routine. Experts recommend you spend at least 150 minutes doing moderate exercise per week.

But is all exercise created equal? Here are the best exercises to strengthen your heart.

Yes, it might seem a little too easy. But walking, especially speed walking, is a great way to strengthen your heart. Walking fast will get your heart rate up and is easier on your joints than other types of exercise. You can walk anywhere at any time. All you need is a pair of supportive shoes. Do a short walk during your lunch break or a longer walk on the weekend. You can listen to music, a podcast, or walk with a friend. The flexibility of walking makes it easy for anyone to do — and to keep doing it.

Although it might not seem like it, yoga is great for your heart health. Doing yoga will help you strengthen and tone your muscles. Certain types of yoga can really get your heart rate up, while still providing the calm that will lower your blood pressure.

Interval training — which alternates between short bursts of high-intensity exercise with longer periods of active recovery — is a great way to get a full-sized workout in a short amount of time. For example, you can do it by running for one minute and walking for three minutes, then repeating the cycle. Raising and lowering of your heart rate helps to burn calories and improves the function of your blood vessels.

Jumping on your bike can do more than just get you from one place to another. Cycling has been shown to help reduce the risk of heart disease. It uses your large muscles in your legs, which helps to elevate your heart rate. Bonus: Cycling has even been shown to improve your mental health.

Whether you choose to hit a yoga class three times a week, go walking with a friend, or swim every morning, regular exercise is essential to taking care of your heart. Always talk to your doctor before you begin an exercise routine.
