The best cardio workout for a healthy heart


Today is a perfect time to get moving on your fitness goals. Regular exercise does more than help you lose weight and build muscle — although it’s definitely good for those reasons!

Aerobic exercise, also known as “cardio” exercise, uses repetitive contraction of large muscle groups to get your heart beating faster and is the most beneficial type of exercise for your cardiovascular system (your heart and blood vessels). Regular cardio workouts can:

My patients often ask me, “What’s the best type of exercise for heart health?” Here’s what I tell them: I don’t care what type of exercise you do as long as you do something!

There is no “magic bullet” for exercise. There’s no “only way” to do it. For example, I’m a cross-trainer. I may work out at the gym for 30 minutes total, but I’ll use three different machines for 10 minutes each to switch it up and keep exercise more interesting for me.

You don’t have to employ the same exercise strategy that I do to get the heart-healthy benefits of cardio exercise. What’s most important is that you exercise regularly. One way you can make that easier is to make it a part of your everyday routine.

We all have a daily routine for personal hygiene — brushing our teeth, taking a shower, and so on. Exercise should be on that list. A lifelong commitment to regular cardio exercise can preserve your heart’s function and keep it “youthful” over the course of your life.

I recommend exercising a minimum of four to five days each week. One key part of this schedule is to vary the types and intensity of exercise you do on different days. By changing up your exercise routine regularly, you’ll work different muscles and lower your risk for overuse injuries. You also can avoid the trap of doing the same thing over and over until you get bored and quit altogether.

I recommend moderate-intensity exercise two or three days a week for at least 30 minutes. You should break a sweat and be a little short of breath during good moderate-intensity exercise, but still be able to carry on a conversation.

In addition to cardio training, strength training one or two days each week is good for your heart and overall health. Strength training makes your muscles stronger and also can improve the strength of your bones and metabolism, which can help you avoid diabetes and other conditions.

The order of the days in which you do your moderate-intensity, high-intensity, longer exercise, and strength training isn’t important. You may want to space out the HIT and strength training to give your muscles a day to recover, avoid injury, and get the most out of your workout time. Weekends or days off work might be a good time to complete your longer workouts.

The heart of the matter

In April 2016, our team completed a two-year, National Institutes of Health-sponsored study looking at how exercise affects participants’ heart health. We studied about 60 middle-aged men and women who had not previously exercised on a regular basis.

The benefits of a healthy heart for longevity and quality of life are too great to ignore. A regular exercise routine will help you keep your heart healthy for years to come. Jog, swim, golf, hike, play basketball, dance, do yoga — whatever you love to do. The most important thing is to get out there and do it.
