World Heart Day, celebrated annually on the 29th of September, is a global initiative aimed at raising awareness about cardiovascular diseases (CVD) and promoting heart-healthy living. As heart disease remains the leading cause of death worldwide, understanding how to keep your heart healthy has never been more important. One of the most effective ways to improve cardiovascular health is through regular exercise.
This guide explores the best exercises for heart health, focusing on cardiovascular workouts that can strengthen your heart, reduce the risk of heart disease, and improve overall well-being. We’ll also discuss how CircleDNA’s Premium DNA Test can help you personalise your fitness routine based on your genetic profile, allowing you to tailor your workouts for maximum heart health benefits.
Why Cardiovascular Health Matters
Your heart is one of the hardest-working organs in your body, pumping blood and delivering oxygen to all your cells 24 hours a day. Over time, however, poor lifestyle choices such as a sedentary lifestyle, poor diet, and smoking can weaken your heart and lead to cardiovascular diseases, including coronary artery disease, high blood pressure, heart failure, and stroke.
The Importance of Cardiovascular Health:
- Prevents Heart Disease: Regular exercise reduces risk factors for heart disease, such as high blood pressure, high cholesterol, and obesity.
- Improves Circulation: Exercise enhances blood flow, which delivers oxygen and nutrients to tissues more efficiently.
- Boosts Mental Health: A healthy cardiovascular system can also support brain health, reducing the risk of stroke and promoting cognitive function.
- Increases Longevity: Studies show that regular physical activity can extend your life by reducing the risk of chronic diseases.
As we mark World Heart Day, let’s focus on the exercises that can help keep your heart strong and healthy.
The Best Exercises for Heart Health
1. Walking
Walking is one of the simplest and most accessible forms of cardiovascular exercise. It’s an excellent starting point for anyone new to fitness or those with existing health conditions. Brisk walking at a pace that gets your heart pumping is particularly effective in improving cardiovascular health.
Benefits of Walking:
- Low impact, making it easy on joints.
- Can be done anywhere—around your neighbourhood, in parks, or even on a treadmill.
- Walking for at least 30 minutes a day, five days a week, has been shown to lower blood pressure and improve cholesterol levels.
How to Get Started:
Start with a brisk 10-15 minute walk and gradually increase the time as your fitness improves. For extra heart health benefits, aim for 30-60 minutes of walking on most days of the week.
2. Running or Jogging
For those looking for a more intense cardiovascular workout, running or jogging is an excellent choice. These exercises engage your whole body, making your heart work harder to pump oxygen-rich blood to your muscles.
Benefits of Running or Jogging:
- Burns calories and helps with weight management, reducing the risk of heart disease.
- Strengthens the heart muscle, improving overall cardiovascular efficiency.
- Studies have shown that regular running can lower the risk of death from heart disease by up to 45%.
How to Get Started:
If you’re new to running, start with a combination of walking and running intervals. For example, run for 1 minute, then walk for 2 minutes, and repeat for 20-30 minutes. As your endurance builds, increase the running intervals and reduce the walking periods.
3. Cycling
Cycling is a fantastic cardiovascular workout that also promotes joint health, making it a great option for those with arthritis or joint issues. Whether on a stationary bike or riding outdoors, cycling elevates your heart rate and engages your lower body muscles.
Benefits of Cycling:
- Improves cardiovascular fitness while being low impact, reducing strain on your joints.
- Aids in building muscular endurance in your legs, helping to support circulation and heart health.
- Research suggests that cycling for 30 minutes a day can reduce the risk of heart disease by up to 50%.
How to Get Started:
If you’re cycling outdoors, choose a safe route with a flat terrain to start, gradually working your way up to hills or longer rides. For indoor cycling, many gyms offer spin classes that provide an intense, heart-pumping workout in a controlled environment.
4. Swimming
Swimming is a full-body workout that improves cardiovascular health without placing stress on the joints. It’s particularly beneficial for individuals with arthritis, osteoporosis, or other musculoskeletal issues.
Benefits of Swimming:
- Engages all major muscle groups while elevating your heart rate, improving both cardiovascular and muscular fitness.
- Swimming for 30-45 minutes at a moderate pace can help lower blood pressure and improve heart function.
- Buoyancy reduces the impact on joints, making it a safe exercise for people of all ages and fitness levels.
How to Get Started:
Aim for 30-minute swim sessions, two to three times per week. If you’re a beginner, start with a mix of swimming and water-based exercises, such as water aerobics, to build endurance.
5. High-Intensity Interval Training (HIIT)
HIIT involves alternating between short bursts of intense activity and periods of lower-intensity exercise or rest. HIIT workouts can be done with various exercises such as running, cycling, or bodyweight exercises like burpees and jumping jacks.
Benefits of HIIT:
- Increases your heart rate quickly, providing a highly effective cardiovascular workout in a short amount of time.
- Boosts metabolism and burns more calories than steady-state cardio, helping with weight management.
- Studies have shown that HIIT can improve heart health, reduce blood pressure, and enhance cardiovascular fitness in as little as 20-30 minutes.
How to Get Started:
Try a basic HIIT workout by alternating between 30 seconds of sprinting and 30 seconds of walking, repeating the cycle for 20 minutes. As your fitness improves, increase the intensity of the high-effort intervals and reduce the rest periods.
6. Strength Training
While not traditionally considered cardiovascular exercise, strength training is essential for heart health. Lifting weights or using resistance bands helps build muscle mass, which increases metabolism and supports cardiovascular function.
Benefits of Strength Training:
- Increases lean muscle mass, which boosts metabolism and supports heart health.
- Reduces visceral fat, a key risk factor for heart disease.
- Improves circulation and blood pressure, helping reduce the risk of cardiovascular events.
How to Get Started:
Incorporate strength training exercises like squats, lunges, push-ups, and weightlifting into your routine two to three times a week. Aim for 8-12 repetitions of each exercise, gradually increasing the resistance as your strength improves.
How Much Exercise Do You Need for a Healthy Heart?
The World Health Organisation (WHO) recommends that adults get at least 150 minutes of moderate-intensity exercise or 75 minutes of vigorous-intensity exercise per week to maintain heart health. This can be broken down into 30 minutes of moderate exercise five days a week, or shorter bouts of more intense activity, such as HIIT.
Incorporating a mix of aerobic (cardio) and anaerobic (strength training) exercises will provide a balanced approach to improving cardiovascular health and overall fitness.
How CircleDNA Can Help You Optimise Your Cardiovascular Workouts

CircleDNA’s report provides insights into your genetic predisposition to stress and sleep disturbances, helping you manage these factors and optimise your heart health through exercise and other lifestyle adjustments.
The Role of Diet in Supporting Cardiovascular Health
While exercise is essential for maintaining heart health, combining physical activity with a heart-healthy diet is the most effective way to reduce your risk of cardiovascular disease.
Key Nutrients for Heart Health:
- Omega-3 Fatty Acids: Found in fatty fish like salmon and walnuts, omega-3s help reduce inflammation, lower triglycerides, and improve overall heart health.
- Fibre: A diet rich in fibre from whole grains, fruits, and vegetables can lower cholesterol levels and reduce the risk of heart disease.
- Antioxidants: Foods high in antioxidants, such as berries, leafy greens, and nuts, help protect the heart by reducing oxidative stress and inflammation.
- Potassium: This mineral helps regulate blood pressure by balancing the effects of sodium. Foods like bananas, sweet potatoes, and avocados are excellent sources of potassium.
Incorporating these nutrients into your daily meals, combined with regular cardiovascular exercise, will ensure that your heart remains strong and healthy.
