Sore muscles are a result of working out and causing damage to the muscle's tissue and fiber. While soreness does not indicate repair to muscle tissue, you do burn some calories when repairing and rebuilding muscle. Muscle soreness may not happen immediately after a workout, and can instead be delayed-onset muscle soreness (DOMS), which can peak within 24 to 48 hours after training. The number of calories burned depends on your body composition and basal metabolic rate (BMR). Muscle is more metabolically active than fat, and having more muscle mass means you burn more calories at the same body weight than if you had less muscle mass.

Sore muscles do burn calories, but not necessarily more than usual
Muscle is more metabolically active than fat and requires energy to maintain, whereas fat tissue is not metabolically active. This means that having more muscle mass increases the number of calories burned at the same body weight compared to having less muscle mass. For example, 10 pounds of muscle would burn 50 calories in a day spent at rest, while 10 pounds of fat would burn 20 calories.
While sore muscles do not burn more calories than non-sore muscles, working out and building muscle mass can help with weight loss. Additionally, strength training has other benefits, such as improving mood, sleep, and cognitive function, as well as reducing the risk of various diseases. It is important to note that the most effective way to burn fat is to focus on a combination of exercise, diet, and overall health, rather than solely on muscle soreness.

Muscle soreness is not an indicator of muscle repair
Muscle soreness, or Delayed Onset Muscle Soreness (DOMS), is not a reliable indicator of muscle repair. DOMS is an inflammatory response to microscopic tears in the muscle fibres and connective tissues caused by eccentric muscle action. This can be brought about by unaccustomed or intense exercise, or a new type of exercise that the body is not used to.
While DOMS may provide some indication of muscle damage, it is not a definitive measure. Studies have shown that DOMS can be significantly reduced with subsequent training sessions, and this effect can persist for several weeks. As such, DOMS is more common at the beginning of a new programme or for beginners, and eases as the body adapts.
The presence and intensity of DOMS can depend on various factors, such as the type of exercise, the intensity of the workout, and individual differences in physiology. For example, a 2012 study found that a 20-minute cool-down of low-intensity cycling after strength training reduced soreness in the quadriceps muscle two days later. Additionally, hydration status can influence muscle soreness, with one study showing that men who drank water before, during, and after exercising in hot, humid temperatures experienced less muscle soreness than those who did not hydrate sufficiently.
While muscle soreness is not a direct indicator of muscle repair, it is important to address and manage DOMS to optimise recovery and performance. This can include rest, gentle movement, stretching, hydration, and proper warm-up and cool-down routines.

Muscle is more metabolically active than fat
Your metabolic rate is your rate of burning calories, and the ratio of lean tissue to fat is your body composition. Lean tissue includes muscle, organs, connective tissue, and bones, while fat is also known as adipose tissue. Your body composition influences your metabolic rate, or the number of calories you're likely to burn every day.
To burn fat, you need to exercise, eat clean, whole foods, eat a high-protein diet, improve your body composition, and be in a slight calorie deficit. Strength training can help to build muscle strength and stamina, and it can also help to preserve metabolically active muscle mass while you lose body fat.
Burning calories is different from burning fat. Calories are energy, and fat is stored excess energy. You accumulate fat on your body when you consume more calories than you burn daily.

Strength training is important for losing fat and keeping your body strong and healthy
Strength training is a vital component of any fitness regimen aimed at losing fat and keeping your body strong and healthy. While cardio exercises are great for increasing heart and breathing rates, strength training, also known as resistance training, helps build muscle strength, power, and endurance.
One of the key benefits of strength training is its ability to increase muscle mass, which in turn boosts your metabolism. With a higher metabolic rate, your body burns more calories even at rest, making it easier to maintain a calorie deficit, which is crucial for losing fat. Additionally, strength training can lead to excess post-exercise oxygen consumption (EPOC), where your body continues to use increased energy after a workout to recover, repair, and return to its pre-exercise state, burning even more calories.
Another advantage of strength training is that it can be tailored to your body type and fitness level. Whether you're a beginner or an advanced athlete, you can adjust the weights and exercises to challenge your muscles appropriately. This adaptability ensures that anyone can engage in strength training and experience its benefits over time.
Furthermore, strength training offers a range of additional health benefits beyond fat loss. It can improve your posture, enhance your endurance, and reduce the risk of injuries. Research also suggests that strength training may have positive effects on managing diabetes, lowering blood sugar levels, and improving insulin response. Additionally, it may even contribute to brain health and help prevent cognitive decline.
By incorporating strength training into your fitness routine, you can effectively lose fat, build muscle, and promote overall health and well-being. Remember to combine strength training with a healthy, nutritionally balanced diet and adequate rest days for optimal results and a strong, healthy body.

High-intensity strength training burns extra calories for up to 72 hours after your workout
High-intensity strength training is an excellent way to burn calories, not only during your workout but for up to 72 hours after your session has ended. This is due to a phenomenon known as the "afterburn effect", where your body continues to use oxygen at an elevated rate, resulting in increased calorie expenditure.
The afterburn effect, also known as excess post-exercise oxygen consumption (EPOC), occurs when your body needs to restore its resting metabolic rate after an intense workout. During high-intensity training, your body consumes more oxygen, leading to a greater EPOC and, consequently, more calories burned after your workout. The harder your body works to recover, the more calories you'll burn.
Research supports the notion that high-intensity strength training has a significant afterburn effect. Studies have shown that metabolism can remain elevated for up to 48 hours after very high-intensity workouts. Additionally, a 2011 study found that some individuals burned almost 200 extra calories in the 14 hours following a high-intensity interval training (HIIT) session.
It's important to note that the number of calories burned during and after a workout can vary depending on various factors, including the training volume, intensity, and duration. For example, circuit training and HIIT consume the most calories but require longer recovery times. On the other hand, endurance training has a lower and shorter afterburn effect but may result in more calories burned during the actual workout.
While sore muscles are not a direct indicator of fat burning, they do indicate that you've exercised and experienced muscle damage at a tissue and fiber level. Sore muscles can burn calories, but this may or may not come from body fat. The number of calories burned also depends on your body composition and basal metabolic rate (BMR).

Frequently asked questions
Yes, healing muscles do burn calories, but it is not a significant amount. When you work out, you tear muscle fibres, which your body then has to repair, and this repair process requires energy in the form of calories.
Sore muscles do not burn fat directly. However, muscle is more metabolically active than fat, so having more muscle mass means you will burn more calories at the same body weight than if you had less muscle mass.
High-intensity exercises are the most efficient way to burn calories, but low-intensity exercises are also effective if performed for a longer duration.
Body composition plays a major role in determining the amount of calories burned each day. The amount of lean muscle tissue in the body is the primary driver of metabolic rate, which influences the number of calories burned.
Being physically active is not the only way to burn calories. Improving your sleep, managing stress, and maintaining a healthy diet can also help promote weight loss and increase muscle mass.
