What makes 90 minutes of weekly exercise an optimal choice?
In the pursuit of maintaining a healthy heart, regular exercise plays a crucial role. According to various health sources, including MedicineNet and the American Heart Association, aerobic exercise is particularly beneficial for heart health.
Aerobic exercise, which includes activities like jogging, swimming laps, and moving furniture, directly exercises the heart muscle, promoting good circulation and burning the most calories. Even for those with heart failure, exercise can be beneficial, though certain exercises should be avoided.
Minimal beneficial exercise for heart health can be as little as 3 minutes of moderate incidental physical activity per day. This can lower the risk of cardiovascular events significantly. Vigorous activity is even more efficient, where about 4.6 minutes daily can yield similar benefits. Moderate activity includes brisk walking or chores that raise your heart rate so you can speak but not sing comfortably.
The American Heart Association recommends at least 150 minutes of moderate-intensity aerobic exercise per week, roughly 30 minutes a day for five days a week, to significantly reduce the risk of cardiovascular diseases like heart disease and hypertension. However, even fewer minutes on a flexible schedule—as little as 150 minutes total compressed into 1-2 days per week ("weekend warrior" style)—have shown a 33% reduction in cardiovascular mortality risk compared to inactivity.
Types of exercise most effective for heart health are primarily aerobic or cardiovascular activities that increase heart rate and breathing. These include brisk walking, running, cycling, swimming, dancing, and aerobic fitness classes. These improve circulation, lung capacity, and endurance, contributing broadly to cardiovascular health.
Walking about 7,000 steps a day (moderate intensity) is associated with a lowered risk of heart disease and other chronic illnesses. Even lower daily step counts (around 4,000 steps) also show measurable health benefits compared to very low activity levels.
Overall, any amount of physical activity is beneficial, and more intense or sustained activity yields greater heart protection. Incorporating short bouts of higher intensity movement when possible (e.g., taking stairs) amplifies benefits.
In summary, minimal daily moderate exercise (around 3-5 minutes) or accumulating 150 minutes weekly in any schedule improves heart health, with aerobic exercises being the most effective. For those who don't love exercise but are looking to significantly benefit their heart, 30 minutes a day at least three days a week is ideal.

- To support heart health, engaging in moderate exercises like brisk walking or chores that raise the heart rate, can significantly lower the risk of cardiovascular events, even in as little as 3 minutes per day.
- Beyond aerobic exercises such as jogging, swimming laps, and dancing, science shows that incorporating fitness-and-exercise activities like taking stairs and moving furniture can also directly benefit heart health.
- As observed in scientific studies, regularly participating in health-and-wellness activities, specifically aerobic exercises like swimming, cycling, and fitness classes, can contribute broadly to cardiovascular health and potentially reduce the risk of heart disease and hypertension.
