When it comes to weight loss and calorie burning, two popular forms of exercise often come to mind: strength training and cardio. Both have their own unique benefits and drawbacks, and the question of which one burns more calories often sparks heated debates among fitness enthusiasts. In this article, we’ll delve into the intricacies of both forms of exercise and explore whether strength training truly burns more calories than cardio.
Understanding Strength Training and Cardio
Before we dive into the comparison, let’s first understand what strength training and cardio entail.
Strength Training
Strength training, also known as resistance training, involves using weights, resistance bands, or your own body weight to build muscle and strength. This type of exercise focuses on short, intense bursts of activity, targeting specific muscle groups. Examples include weightlifting, bodyweight exercises like push-ups and squats, and using resistance machines at the gym.
Cardio
Cardio, or aerobic exercise, is any form of physical activity that increases your heart rate and breathing for an extended period. It’s primarily designed to improve endurance and cardiovascular health. Common examples include running, cycling, swimming, and brisk walking.
Calorie Burning During Exercise
Now, let’s look at how many calories each type of exercise burns.
Calorie Burning in Strength Training
Strength training burns calories during the workout itself. The number of calories burned depends on several factors, including your body weight, the intensity of the exercise, and the duration. For instance, a one-hour session of intense weightlifting might burn around 462 calories for a person weighing 77 kilograms (169.4 pounds), while someone weighing 54 kilograms (118.8 pounds) might burn around 326 calories.
Moreover, strength training has a unique advantage: it continues to burn calories after the workout. This is due to excess post-exercise oxygen consumption (EPOC), a phenomenon where your body requires more oxygen to return to its resting state after intense exercise. EPOC can increase your metabolic rate for several hours after a strength training session, leading to additional calorie burning.
Calorie Burning in Cardio
Cardio exercises, on the other hand, also burn calories during the workout. However, the rate of calorie burning is usually more consistent and steady, rather than the short, intense bursts seen in strength training. For example, running at a moderate pace for an hour might burn around 600-700 calories for someone weighing around 70 kilograms (154 pounds), depending on factors like speed and terrain.
While cardio doesn’t typically provide the same level of EPOC as strength training, it keeps your heart rate elevated and burns calories steadily throughout the workout. This makes it an excellent choice for those looking to maintain a consistent calorie deficit over an extended period.
Calorie Burning After Exercise
As mentioned earlier, strength training has a unique advantage in that it continues to burn calories after the workout due to EPOC. This effect can last for several hours, depending on the intensity and duration of the exercise. Studies have shown that both resistance training and high-intensity interval training (HIIT) can increase EPOC more than steady-state cardio exercises like jogging or cycling.
This means that even after you finish your strength training session, your body is still working hard to recover and repair the muscle fibers that were damaged during the workout. This process requires energy, which comes from burning calories.
In contrast, cardio exercises typically don’t provide the same level of EPOC. While your heart rate and breathing might stay elevated for a short period after the workout, the calorie-burning effect usually tapers off more quickly.
Building Muscle and Boosting Metabolism
Another key factor to consider when comparing strength training and cardio is their impact on muscle mass and metabolism.
Muscle Mass and Metabolism
Strength training helps increase your lean muscle mass, which is metabolically active tissue that requires energy even at rest. The more muscle mass you have, the higher your resting metabolic rate (RMR) will be. RMR is the number of calories your body requires to perform basic functions like breathing, circulation, and digestion.
Since muscle tissue is more metabolically active than fat tissue, having more muscle mass means your body will burn more calories even when you’re not exercising. This makes strength training an excellent choice for those looking to boost their metabolism and burn calories throughout the day.
Cardio and Muscle Loss
While cardio exercises are excellent for improving cardiovascular health and endurance, they can also lead to muscle loss if not done correctly. Long-duration, low-intensity cardio exercises like marathon running or cycling can actually break down muscle tissue over time, leading to a decrease in muscle mass and metabolism.
To avoid this, it’s important to combine cardio exercises with strength training to maintain or even increase your muscle mass. This will help you burn more calories both during and after exercise, as well as throughout the day.
Practical Considerations
When deciding whether to choose strength training or cardio for weight loss, it’s important to consider your goals, preferences, and lifestyle.
Goals and Preferences
If your primary goal is to build muscle and strength, then strength training is the way to go. It will help you increase your lean muscle mass, boost your metabolism, and burn calories both during and after the workout.
On the other hand, if your goal is to improve cardiovascular health, endurance, and overall fitness, then cardio exercises are a better choice. They will help you increase your heart rate and lung capacity, improve your circulation, and reduce your risk of chronic diseases like heart disease and diabetes.
Lifestyle and Schedule
Another factor to consider is your lifestyle and schedule. Strength training typically requires less time per session than cardio, but it’s more intense and can be more physically demanding. If you have a busy schedule and limited time to exercise, strength training might be a more efficient use of your time.
On the other hand, cardio exercises can be done in shorter bursts and are more flexible in terms of scheduling. You can incorporate them into your daily routine, such as by taking a brisk walk during your lunch break or cycling to work.
Combining Strength Training and Cardio
The best approach for weight loss and overall fitness is often to combine both strength training and cardio. This will help you build muscle, improve cardiovascular health, and burn calories more efficiently.
Creating a Balanced Workout Routine
To create a balanced workout routine, consider incorporating both strength training and cardio exercises into your weekly schedule. For example, you might do strength training three times a week and cardio two or three times a week. Alternatively, you could do a full-body strength training workout followed by a cardio session on the same day.
Listening to Your Body
It’s also important to listen to your body and adjust your workout routine as needed. If you’re feeling particularly sore or fatigued after a strength training session, consider taking an extra rest day or doing a lighter cardio workout instead. Conversely, if you’re feeling particularly energetic and motivated, you might want to increase the intensity or duration of your cardio session.
conclusion
the question of whether strength training burns more calories than cardio is a bit nuanced. While strength training does burn calories during the workout and continues to burn calories after the workout due to EPOC, cardio exercises also have their own unique benefits in terms of improving cardiovascular health and endurance.
The best approach for weight loss and overall fitness is often to combine both forms of exercise into a balanced workout routine. This will help you build muscle, improve cardiovascular health, and burn calories more efficiently. Remember to listen to your body, adjust your workout routine as needed, and stay consistent to achieve your fitness goals.
