It is important to be careful after a heart attack, and a person should consult a cardiologist before returning to physical exercise. Intense activity can have severe consequences, such as causing another heart attack or even sudden cardiac death.

However, exercise is a valuable resource for maintaining health, particularly for those managing heart conditions. Exercise improves heart function and increases lung capacity, reducing the chances of heart failure.

To improve cardiac health while minimizing risk after a heart attack, a person should exercise at low intensity and avoid performing physical activity alone. It is much better to have a person nearby who can assist if necessary.

Cardiac rehabilitation may also be a useful option for those seeking safe, expert-level, and personalized fitness regimens following a heart attack.

While physical exercise can be beneficial after experiencing a heart attack, it is important to begin gradually. The timing of returning to exercise will depend on the extent of the heart attack and any remaining heart damage.

The National Heart Foundation of Australia suggests that a person can return to the activities they were doing previously within a few weeks of having a heart attack. They can return to light walks and muscle movements as soon as a few days later.

However, cases may differ between individuals, so it is essential to check with a healthcare professional before exercising after a heart attack to see what they advise.

Walking is an excellent form of physical activity that has many health benefits. A person can begin a walking exercise program at a slow pace, then increase to a brisk walk over time. Research suggests that increasing the speed of walking is more beneficial than increasing the duration, with moderate to high walking speeds more effective in reducing the chances of heart failure.

A doctor may advise staying away from competitive types of activity due to the intensity of the environment. However, the physical, mental, and social aspects of team sports can help after a heart attack, and people can pursue them many months afterward.

Aquatic exercise, such as swimming or aqua aerobics, can be beneficial for rehabilitation. The buoyancy or ability to float in water reduces the physical stress on the body and allows a person to exercise at their own pace. However, it can be harder to notice exhaustion in the water, so a person should perform aquatic exercises at a lower intensity than land-based exercises.

If there is a lifeguard on duty, it is a good idea to inform them of the previous heart conditions so that they know to pay particular attention while providing safety cover. If a person experiences symptoms such as chest pain, they should exit the water immediately.

Cardiac rehabilitation can provide short- and long-term benefits for people who have had heart attacks. As well as the physical benefits that such programs can offer, attending rehabilitation can reduce the worry that may follow a heart attack, so experts strongly recommend them.

There may be one-to-one programs or group sessions available. A heart attack can be an isolating experience, and it may help to be around people who have been through similar experiences in a group setting.

Depending on the state and country, many support and rehabilitation programs are available through various organizations.

In the United States, the Centers for Disease Control and Prevention (CDC) suggest speaking to a doctor to see if they can recommend a cardiac rehabilitation program. Some insurance plans cover cardiac rehabilitation, which may occur in a hospital, rehabilitation center, or remotely.

It is great to get back to exercising after a heart attack, but a person should always speak to a doctor first to ensure they are ready and undertake proper safety measures.

It is best to start gently through light exercises such as walking or performing static stretches. People should consider their baseline fitness levels when planning an exercise regime. For example, a person who was extremely active before the heart attack is likely to be able to return to exercise at a higher level of fitness than a person who was rarely active.

After experiencing a heart attack, many people are often prescribed cardiac medication known as beta-blockers to treat abnormal heart rhythms (arrhythmias). It is important to note that beta-blockers slow down the heart rate and may increase fatigue with exercise. Consult a doctor if taking beta-blockers before returning to exercise.

Risks and what to avoid

High-intensity activity comes with greater risk. When working out, a person should avoid introducing rigorous training suddenly. Instead, they should aim to build up their fitness levels gradually, using regular, low-intensity movement. It is advisable to begin with aerobic fitness first, then introduce light resistance training progressively.

While strength training can help build muscle and benefit the heart, keeping the weights light and building gradually is best. For several weeks after your heart attack, avoid strenuous activities such as lifting heavy weights, shoveling snow, and other strenuous activities. Taking on too much too soon may spike a person’s heart rate and blood pressure.

Rest days can reduce the risk of injury by giving the body a chance to recover before the next workout.

It is also good practice to avoid exercising alone, as having someone nearby who is aware of the situation can lower risk. They will be able to assist in the case of another heart attack.

It is normal to feel concerned about returning to exercise after any heart condition. Exercising at too high of intensity may trigger another heart attack. However, gradually returning to some form of activity is important, as exercise can improve heart function by lowering blood pressure and slowing down the heart rate.

To enjoy the benefits of exercising while reducing the risks after a heart attack, a person should ease themselves back in. They can start with light exercises such as a slow walking routine and build over time, avoiding pushing the body too hard and sticking to comfortable motions.

It is a good idea to exercise with a companion who is aware of the previous heart attack and can provide immediate assistance if needed.

People should always consult a doctor before beginning to perform physical activity after a heart attack. Every individual is different, and a doctor will be able to advise according to personal needs. Support and rehabilitation programs are available that can help with returning to exercise, such as cardiac rehabilitation.
