Your heart works hard every day, but are you doing enough to help it stay strong?
Many people think heart health comes down to diet alone. However, exercise—especially the right kind—plays a major role. Ignoring it can raise your risk of heart disease, stroke, and even early death.
Science shows that specific types of exercise can protect your heart, lower blood pressure, and even reverse some damage from years of inactivity.
So, where should you start? How do you know what works best—and how much is enough?
According to Dr. Ben Levine, a cardiologist at UT Southwestern Medical Center, aerobic exercise is one of the most effective activities you can do for your heart. Also known as cardiovascular or “cardio” exercise, it gets your heart pumping and your lungs working harder. This type of exercise strengthens the heart, improves blood flow, lowers blood pressure, and reduces the risk of serious conditions like heart disease, stroke, and Alzheimer’s disease. It also helps lower cholesterol and blood sugar levels.
One major study led by Dr. Levine focused on middle-aged adults (around 53 years old) who had not exercised regularly before. After two years of consistent aerobic training, these individuals showed significant improvement in heart flexibility—what Dr. Levine calls a more “youthful” heart. This means their hearts became more efficient at pumping blood, which reduces the strain on the cardiovascular system. The study included around 60 participants and demonstrated that even starting in midlife, you can still reverse some damage caused by years of inactivity.
In a follow-up study, Dr. Levine and his team trained people at risk of heart failure due to high blood pressure and early signs of heart strain. After a year of regular aerobic exercise, these participants also experienced improved heart elasticity.
This shows that cardio exercise not only benefits healthy people but can also help prevent the worsening of heart-related conditions in those already at risk.
Meanwhile, according to the American Heart Association (AHA), adults should aim for at least 150 minutes of moderate-intensity aerobic activity each week, or 75 minutes of vigorous activity. Brisk walking, one of the most accessible forms of aerobic exercise, falls under moderate intensity. The AHA emphasizes that spreading activity throughout the week is ideal. Activities like walking, swimming, and dancing are all great ways to meet these goals.
One report shows that just 3,867 steps per day lowers the risk of death from any cause. Even fewer—around 2,337 steps—can cut the risk of dying from heart-related problems. The more you walk beyond these numbers, the greater the benefits.
Helen Alexander, a cardiac physiotherapist at Nuffield Health, also explains that aerobic activity improves how well your heart and circulatory system work, helping you do daily tasks without getting tired. It also supports better sleep, reduces stress, and keeps your mood stable.
Follow these steps to train safely and effectively.
1. Warm up your body. Before you lift anything, get your body ready. A proper warm-up increases blood flow to your muscles and prepares your joints for movement. You can march in place, walk briskly for five to ten minutes, or do some jumping jacks. This simple step protects your body from injury and helps you perform better during your workout.
2. Choose the right weights. Pick a weight that feels manageable. You should be able to lift it about 8 to 12 times before feeling tired. That’s called a repetition, or “rep.” The weight should feel challenging by the last few reps, but not painful. If it feels too easy, the weight is too light. If you can’t make it past five or six reps, it’s too heavy. Start with what feels right and go from there.
3. Focus on major muscle groups. Aim to work all the large muscle groups in your body. That includes your legs, chest, back, shoulders, arms, and stomach. You don’t need fancy equipment. You can use hand-held weights, resistance bands, or even your own body weight. For example, squats strengthen your legs, pushups work your chest and arms, and planks target your core.
4. Perform the movements slowly and safely. Move in a smooth and steady way. Lift the weight slowly, then lower it just as slowly. Rushing can lead to injury and doesn’t help your muscles grow. Keep your posture strong. Don’t lock your joints, and never jerk the weight.
5. Do one or two sets. Start with one set of each exercise. A set is a group of reps—usually eight to twelve. Rest for 30 to 60 seconds between each set. If you feel comfortable and want to do more, add a second set later on.
6. Rest between workouts. Don’t work the same muscle group two days in a row. Muscles grow and get stronger during rest, not during exercise. If you train your legs on Monday, wait until Wednesday or Thursday before doing leg exercises again. On the in-between days, you can work other muscles or do light aerobic activity like walking or swimming.
According to the NIA, balance exercises help older adults avoid falls, which can lead to serious injuries and stop them from being active. Regular balance training helps keep the body steady both when standing still and when moving.
The NIA recommends doing balance exercises about three times a week. These include:
1. Tai chi or yoga: If you’ve done tai chi or yoga before, you can use those moves too. Choose slow, steady movements that help you stay balanced. If you’re new to these, you can look for beginner videos or ask a teacher to show you how.
2. Standing on one foot: Stand up straight with your feet together. Slowly lift one foot off the ground and try to stay balanced for 10 to 15 seconds. Then, put your foot down and try the same thing with your other foot. Do this three times on each side.
3. Walking heel-to-toe: Stand tall and place one foot directly in front of the other so your heel touches the toes of your back foot. Walk forward in a straight line like this for ten steps. Then turn around and walk back the same way.
These types of movements don’t directly strengthen your heart, but they help you stay on your feet safely. That means you can keep doing heart-healthy exercises like walking or swimming without worrying about falling. This kind of safety support is important, especially as you age.
Harvard Health Publishing also highlights how balance declines over time due to changes in your vision, inner ear, and leg strength. But the good news is that balance exercises can slow or even reverse these effects. They suggest that balance training is useful even if you don’t think you have balance problems yet. Good balance helps you keep moving and prevents injuries that could limit your physical activity. A physical therapist can also create a personalized plan, especially if you've had a fall before. With better balance, you can stay active, and that ongoing activity is good for your heart.
According to research discussed in the Johns Hopkins Medicine report, High-Intensity Interval Training, or HIIT, has shown clear benefits for heart health. In a HIIT workout, short bursts of very intense activity are alternated with brief recovery periods. This form of training pushes your body to work hard for a short time, then allows it to recover just enough before the next burst. That cycle creates powerful effects on your heart and overall cardiovascular system.
One major benefit of HIIT is that it helps your muscles use oxygen more efficiently. This means your heart doesn’t need to pump as hard to send oxygen-rich blood throughout your body. Over time, that makes your heart stronger and less strained. It also reduces stress hormones, which lowers the pressure on your heart during both exercise and rest.
In practical terms, people who include HIIT in their exercise routine improve their heart rate control, reduce their blood pressure, and boost their aerobic capacity.
To do an HIIT workout, consider the following:
1. First, pick an activity you like, such as walking, running, biking, or jumping jacks. Make sure you have enough space and feel safe doing it. Start with a short warm-up. Move slowly for a few minutes to get your body ready. This could be light walking or gentle stretching.
2. Now it’s time for the high-intensity part. Go as fast or as hard as you can for about 30 seconds. This should feel tough and get your heart beating faster.
3. After that, slow down and rest. Walk or move gently for about 1 to 2 minutes so your body can recover. Repeat this pattern. Do another round of fast movement for 30 seconds, then another slow break. Try to keep going for about 20 to 30 minutes total.
4. When you’re done, cool down. Walk slowly or stretch for a few minutes to help your body relax.
5. Start with just a few intervals and add more as you get stronger. Always listen to your body, and rest if you need to. If you’re new to exercise or have health problems, check with a doctor before starting HIIT.
Walking, swimming, lifting weights, and short bursts of intense movement all play a part. Each type of exercise brings unique benefits, from lowering blood pressure to improving balance and building strength.
You don’t need fancy equipment or long hours at the gym. Start small, stick with it, and add variety when you can. If you're wondering when to begin, the answer is simple: now.
