How Much Time You Should Spend Exercising Depends on Several Factors

On the one hand, the type of activity you do matters because a HIIT training session does not have the same intensity as going for a walk with your dog.

Of course, your physical condition also comes into play here. As much as you may want to spend hours in the gym to burn more calories or gain muscle, this may not be suitable if you are in poor shape. Your body may not tolerate the workload, and pushing too hard could even be dangerous.

Ultimately, your goal will also influence your routine. You may want to stay healthy, lose weight, or gain muscle through exercise. Setting realistic fitness goals can help you decide how much exercise to do and track your progress.

Of course, any amount of exercise is better than none. That being said, the answer to how long you should exercise will depend on your state of health and your goals.

How Much Exercise Should You Do to Be Healthy?

The physical activity guidelines set by health organizations such as the WHO can help you understand how much exercise you should aim for.

They serve as minimum recommendations to help combat the effects of a sedentary lifestyle. These guidelines are framed according to age groups.

For the average adult, they recommend 150 to 300 minutes of moderate-intensity aerobic physical activity a week.

Alternatively, adults can aim for 75 to 150 minutes of vigorous-intensity aerobic physical activity or an equivalent combination of both. The guidelines also recommend performing strengthening activities that work all major muscle groups on two or more days a week.

Several aspects, such as an increase in breathing rate, heart rate, or body temperature, can help you identify the intensity of your workout.

To give you an idea, moderate-intensity exercise generally allows you to talk but makes singing difficult. You may notice that your breathing and heart rate have increased.

More specifically, brisk walking, cycling, and mowing the lawn can count as moderate-intensity aerobic activities, while running or fast dancing can be vigorous-intensity activities, depending on your effort.

Strength Training Can Include Using Heavy Machines, Dumbbells, or Your Body Weight

According to these guidelines, your goal for staying healthy should include regular aerobic activity and strength training. For example, you could aim for around 30 minutes of moderate-intensity activity on most days, adjusting your schedule to reach the recommended weekly total.

It is also essential to take into account the time you spend sitting. The more hours you remain inactive, the more important it becomes to incorporate movement into your day. Try to take regular breaks from sitting and find opportunities to walk or stretch.

How Much Exercise Should You Do to Lose Weight?

To lose weight, you generally need to burn more calories than you consume. Therefore, your diet is a significant factor.

Exercise also plays an important role. Both diet and physical activity influence energy balance, while strength training can help preserve muscle mass during weight loss.

It is useful to alternate cardiovascular and strength training. Cardiovascular exercise supports heart health and calorie expenditure, while strength training helps you build or maintain lean muscle.

The amount of exercise needed for weight loss varies from person to person. Some people may need more than the minimum recommended activity to achieve their goals, depending on their diet, starting weight, and daily activity level.

A practical approach is to start with manageable sessions and gradually increase the duration and intensity as your fitness improves. Combining regular exercise with sustainable eating habits is generally more effective than relying on exercise alone.

Duration of Your Workout When Looking to Gain Muscle

Do not make the mistake of thinking that muscle-activating exercises will automatically make you look like the Hulk.

As people age, muscle mass and strength can decline. Including strength training regularly in your routine can help reduce this impact and support healthy movement.

To build muscle, focus on resistance exercises that challenge the major muscle groups, using weights, resistance bands, machines, or your body weight. Increase the challenge gradually as your strength improves, and allow enough recovery time between demanding sessions.

How often you train depends on your experience, goals, and recovery needs. Read our guide on how often you should exercise at the gym for more information about planning your weekly training schedule.

The best time to exercise is also the time you can follow consistently. Explore the best time of day to work out to find a schedule that fits your routine and preferences.

Remember that consistency, gradual progress, adequate recovery, and a balanced diet all contribute to reaching your fitness goals. If you have a chronic health condition or are new to exercise, consult a healthcare professional when you need help choosing a safe routine.
