Strength training, also known as resistance training, is a form of exercise designed to improve muscle strength, endurance, and size. This type of workout involves using resistance, whether from free weights, machines, resistance bands, or bodyweight exercises, to challenge and strengthen muscles. So, How many calories does an hour of strength training burn? Unlike cardiovascular exercises, which focus primarily on improving heart health, strength training targets specific muscle groups to promote muscle growth, tone, and overall body strength.
Strength training is essential for building lean muscle mass, which in turn boosts metabolism and aids in fat loss. It plays a vital role in improving functional strength, helping individuals perform everyday activities with ease and reducing the risk of injury. Moreover, regular strength training enhances bone density, improves posture, and supports joint health. For those looking to lose weight, strength training is an effective strategy, as it not only burns calories during exercise but also increases the body’s ability to burn calories at rest, making it a crucial part of any fitness regimen.
How Many Calories Does an Hour of Strength Training Burn?
Strength training, often referred to as resistance training or weightlifting, involves using your muscles to move weight against resistance. Many people incorporate strength training into their fitness routines to build muscle, enhance strength, and boost metabolism.
The number of calories burned during strength training can vary depending on several factors, including your body composition, workout intensity, and overall fitness level. Understanding these elements can help you estimate how much energy you’re expending during your workout and how it aligns with your fitness goals.
Average Calorie Burn During Strength Training
On average, an hour of strength training can burn between 200 to 400 calories. However, this range varies based on individual factors. For example, someone who is heavier or has more muscle mass tends to burn more calories than someone who is lighter or has less muscle mass.
Additionally, the intensity of your strength training session plays a key role in the number of calories burned. High-intensity workouts, such as circuit training or strength training with minimal rest between sets, can lead to a higher calorie burn compared to traditional weightlifting, where rest periods are longer.
Two Phases of Calorie Burn During Strength Training
When engaging in strength training, the calorie burn occurs in two distinct phases:
- During the Workout: The act of lifting weights burns calories as your muscles exert energy to lift and move the weights. The heavier the weights and the more intense the exercises, the greater the number of calories burned during this phase.
- After the Workout (EPOC Effect): The Excess Post-Exercise Oxygen Consumption (EPOC) refers to the increase in calorie burn that occurs even after the workout has been completed. During this phase, your body continues to burn calories as it works to restore normal metabolic function. The more intense the strength training session, the longer and more pronounced the EPOC effect will be, leading to a higher overall calorie burn.
Factors That Influence Calorie Burn During Strength Training
While the average calorie burn during strength training ranges from 200 to 400 calories per hour, several factors contribute to how many calories you’ll burn. These factors include:
Body Weight
- Heavier individuals burn more calories during strength training because their body mass requires more energy to move weights.
- As body weight increases, the body works harder to support movement, resulting in a higher calorie expenditure.
- Individuals with a larger body mass may experience a greater calorie burn during both resistance exercises and cardio.
Muscle Mass
- The more muscle mass you have, the more calories you burn even at rest, as muscles require more energy to sustain.
- Muscle tissue is metabolically active, meaning individuals with more muscle mass naturally burn more calories during strength training.
- Having a higher muscle-to-fat ratio increases overall calorie burn during exercise and throughout daily activities.
Workout Intensity
- HIIT strength training, such as circuit training or high-rep exercises, elevates the heart rate and burns more calories than moderate-intensity workouts.
- Compound exercises (e.g., squats, deadlifts, and bench presses) that engage multiple muscle groups lead to a higher calorie expenditure.
- The intensity of the workout directly correlates to the calorie burn—shorter rest periods and quick transitions between exercises boost the overall energy expenditure.
Rest Periods
- Shorter rest periods between sets keep the heart rate elevated, leading to an increase in the total number of calories burned.
- Quick transitions between exercises help maintain intensity, optimizing calorie burn during strength training sessions.
- Longer rest periods allow for muscle recovery, which may reduce the overall calorie burn per workout.
Exercise Variety
- Compound exercises, such as squats and deadlifts, work multiple muscle groups simultaneously, resulting in a higher calorie burn than isolation exercises like bicep curls.
- Variability in exercises helps engage different muscle groups, ensuring a more comprehensive calorie burn throughout your training session.
- Alternating between different exercises and using a range of movement types (e.g., push, pull, squat) can maximize calorie expenditure.
Fitness Level
- Fitter individuals tend to burn fewer calories during the same workout because their bodies are more efficient at completing exercises.
- As your fitness level increases, your body becomes more adept at using energy, which can lower the calorie burn during the same exercises.
- Those new to strength training or with lower fitness levels may burn more calories, as their bodies work harder to complete each movement.
Benefits of Strength Training Beyond Calorie Burn
While calorie burn is an important aspect of strength training, the benefits extend far beyond just weight loss. Strength training plays a crucial role in overall health and fitness, including:
Improved Muscle Mass and Strength
Strength training is key to increasing muscle mass, which directly enhances physical strength and overall endurance. As you build muscle, your body becomes more efficient, allowing you to perform daily activities with greater ease. More muscle mass also increases your resting metabolic rate, meaning your body burns more calories even when at rest. This long-term benefit supports weight management and improves athletic performance, making strength training essential for overall health.
Enhanced Bone Health
Engaging in weight-bearing exercises like strength training significantly improves bone density. This is particularly important for preventing osteoporosis and reducing the risk of fractures, especially in older adults. Strength training encourages bone remodeling, leading to stronger bones. The increased load on bones during resistance training stimulates bone-forming cells, which promotes better bone health. For those concerned about aging or bone-related conditions, strength training is an effective preventative measure.
Boosted Metabolism
Strength training is an effective way to boost your metabolism, helping you maintain or lose weight over time. The increase in lean muscle mass that comes from regular strength training allows your body to burn more calories, even when you’re not working out. This is because muscle tissue is metabolically active and requires more energy to sustain than fat. Over time, this metabolic boost leads to better weight management and overall body composition.
Improved Mental Health
Strength training has been shown to have significant benefits for mental health. Regular strength workouts release endorphins, the body’s natural “feel-good” chemicals, which help reduce symptoms of anxiety and depression. In addition, strength training can increase self-esteem and confidence, especially as you see physical improvements and achieve your fitness goals. The mental clarity gained through strength training can provide a sense of accomplishment and positively impact your overall well-being.
Better Functional Fitness
Strength training improves functional fitness, which refers to the ability to perform everyday tasks with greater ease and less risk of injury. This includes activities like lifting heavy groceries, climbing stairs, or performing manual labor. By strengthening muscles and enhancing coordination, strength training helps increase mobility, balance, and flexibility. With a well-rounded strength routine, you can enjoy an enhanced quality of life and reduce the likelihood of strain or injury during daily activities.
