How Much Exercise Should I Do per Day?

May 6, 2023

Exercise is a crucial component of a healthy lifestyle. It can help improve physical and mental health, reduce the risk of chronic diseases, and increase overall well-being. However, one of the most common questions people have is how much exercise they should do per day. The answer to this question can depend on various factors such as age, fitness level, and health conditions. In this article, we will explore how much exercise you should do per day to maintain optimal health.

The Physical Activity Guidelines for Americans, issued by the U.S. Department of Health and Human Services, recommends that adults aim for at least 150 minutes of moderate-intensity aerobic physical activity or 75 minutes of vigorous-intensity aerobic physical activity each week. This equates to about 30 minutes of moderate-intensity exercise five days a week or 25 minutes of vigorous-intensity exercise three days a week. Additionally, the guidelines suggest that adults should engage in muscle-strengthening activities that work all major muscle groups at least two days a week.

However, it is important to note that these guidelines are minimum recommendations for maintaining general health and may not be sufficient for achieving specific fitness goals or addressing certain health conditions. For example, individuals looking to lose weight or build muscle may need to engage in more exercise than the recommended minimum. Similarly, individuals with chronic health conditions may need to adjust their exercise routine based on their specific needs and limitations.

Aerobic Exercise Recommendations

Aerobic exercise, also known as cardio, is any activity that increases your heart rate and breathing rate, such as brisk walking, cycling, or swimming. The Physical Activity Guidelines recommend that adults aim for at least 150 minutes of moderate-intensity aerobic physical activity each week. Moderate-intensity aerobic activity refers to exercise that increases your heart rate and breathing rate but still allows you to carry on a conversation.

Alternatively, adults can engage in 75 minutes of vigorous-intensity aerobic physical activity each week. Vigorous-intensity aerobic activity refers to exercise that makes it difficult to carry on a conversation and increases your heart rate and breathing rate significantly, such as running or high-intensity interval training.

It is also important to note that breaking up your exercise into shorter bouts throughout the day can be just as effective as doing it all at once. For example, doing three 10-minute walks per day can provide the same health benefits as one 30-minute walk.

Muscle-Strengthening Exercise Recommendations

Muscle-strengthening exercises, also known as resistance or strength training, work your muscles against a resistance to improve strength, endurance, and muscle mass. The Physical Activity Guidelines recommend that adults engage in muscle-strengthening activities that work all major muscle groups at least two days a week.

Examples of muscle-strengthening activities include weight lifting, bodyweight exercises (such as push-ups and squats), and resistance band exercises. It is recommended to perform at least one set of 8-12 repetitions of each exercise, using a weight or resistance that is challenging but still allows you to maintain proper form.

Benefits of Exercise

Engaging in regular exercise has numerous health benefits, both physical and mental. Some of the physical benefits of exercise include:

Reduced risk of chronic diseases such as heart disease, stroke, diabetes, and some cancers Improved cardiovascular health, including lower blood pressure and cholesterol levels Improved bone health and reduced risk of osteoporosis Improved strength and flexibility Improved immune function Reduced risk of falls and improved balance in older adults Reduced risk of weight gain and obesity The mental health benefits of exercise are equally as important. Regular exercise has been shown to:

Reduce symptoms of anxiety and depression Improve mood and self-esteem Reduce stress levels Improve cognitive function and reduce the risk of cognitive decline

Tips for Incorporating Exercise into Your Routine

While the benefits of exercise are clear, many people struggle to incorporate it into their daily routine. Here are some tips to help you get started:

Find an activity you enjoy: Whether it’s dancing, hiking, or swimming, find an activity that you enjoy and are more likely to stick with.

Start small If you’re new to exercise, start with small goals and gradually increase your activity level over time.

Make it a habit Schedule your exercise into your daily routine, just like you would any other appointment.

Find a buddy Exercise with a friend or family member to make it more enjoyable and hold each other accountable.

Mix it up Incorporate different types of exercise into your routine to keep it interesting and prevent boredom. Conclusion

The Physical Activity Guidelines for Americans recommend that adults aim for at least 150 minutes of moderate-intensity aerobic physical activity or 75 minutes of vigorous-intensity aerobic physical activity each week, along with muscle-strengthening activities at least two days a week. However, these are minimum recommendations, and individuals may need to adjust their exercise routine based on their specific goals and health conditions.

Regular exercise has numerous physical and mental health benefits and should be a key component of a healthy lifestyle. By finding an activity you enjoy and incorporating exercise into your daily routine, you can improve your overall health and well-being.

In summary, physical activity and exercise are vital for optimal health and well-being. Current guidelines recommend at least 150 minutes per week of moderate-intensity aerobic activity, or 75 minutes of vigorous-intensity aerobic activity, along with muscle-strengthening activities at least two days per week. These guidelines are based on a large body of scientific evidence demonstrating the beneficial effects of exercise on numerous health outcomes, including cardiovascular disease, type 2 diabetes, obesity, mental health, and cancer.

Furthermore, research has shown that higher levels of physical activity and exercise are associated with even greater health benefits, and that there is no upper limit to the health benefits of exercise. However, it is important to note that individuals should consult with their healthcare provider before beginning an exercise program, particularly if they have any pre-existing medical conditions or risk factors.

Finally, it is crucial to consider the individual’s preferences and lifestyle when prescribing exercise, as adherence is key to achieving the health benefits of physical activity. Therefore, exercise should be enjoyable, feasible, and sustainable in the long-term. With these considerations in mind, individuals can develop an exercise routine that meets their individual needs and goals, while improving their overall health and well-being.
