Running is a popular form of exercise, with people running for various reasons, such as reducing stress, improving health, and competing in races. When it comes to shredding muscle, the answer is nuanced. Running can help build lower body muscles, particularly in the quadriceps and hamstrings, but this depends on the intensity and duration of the runs. High-intensity, short-duration running, like sprinting or HIIT workouts, can promote muscle growth, while long-distance running can hinder it by increasing muscle protein breakdown (MPB) and causing muscle damage. Additionally, running burns calories and can increase appetite, so it can be a tool for creating a calorie deficit, which is necessary for fat loss, but it should be combined with a diet that includes sufficient protein to support muscle growth and preservation.

What You'll Learn
Running can build lower body muscles
Running is a great way to build lower-body muscles, especially in the quadriceps and hamstrings. High-intensity, short-duration running workouts like HIIT have been shown to build muscle in the lower body. One study found that college students who performed HIIT workouts involving 4 sets of running at near-maximum capacity for 4 minutes, followed by 3 minutes of active rest, showed an almost 11% increase in the muscle fiber area of their quadriceps.
Sprinting and interval training are particularly effective for building lower body muscles. For example, you can try 6 sets of 20-second sprints at maximum intensity, followed by 2 minutes of light jogging, or 4 sets of 45-second sprints at moderate intensity, separated by 5 minutes of walking or light jogging. Running uphill or downhill can also increase muscle growth by requiring more core engagement and greater activation of the calves.
However, it's important to note that long-distance running can actually hinder muscle growth. This is because it can increase muscle protein breakdown (MPB) and interfere with muscle growth. To support muscle growth, it's crucial to have a balanced diet with adequate nutrients, especially protein, carbs, and fats. Additionally, warming up and cooling down are important for preventing injuries and enhancing recovery.
While running primarily targets the lower body, it's important not to neglect your upper body. The muscles in your arms, shoulders, chest, and upper back can significantly impact your running performance and posture. A strong core is also essential for runners, as it helps to stabilize the body and protect the spine from excessive force during strides.

High-intensity, short-duration running builds muscle
Running is a popular form of exercise that has many health benefits, including weight loss and improved endurance. However, the impact of running on muscle growth depends on the type of running performed. While long-distance running may inhibit muscle growth due to muscle damage, high-intensity, short-duration running, such as sprinting and HIIT (High-Intensity Interval Training), can promote muscle growth, particularly in the lower body.
High-intensity, short-duration running workouts like HIIT can effectively build lower body muscle when performed consistently. HIIT involves short bursts of intense exercise, such as sprinting or hill sprints, alternated with recovery periods of walking or light jogging. This type of training stimulates muscle growth by creating a physiological stress response that promotes muscle protein synthesis (MPS) while temporarily suppressing muscle protein breakdown (MPB).
The key to maximizing muscle growth with HIIT is to focus on exercises that target the lower body, such as the quadriceps and hamstrings. Examples of HIIT workouts for muscle building include performing sets of 45-second sprints at moderate intensity or 30-second hill sprints, with appropriate rest periods in between. It is recommended to perform these workouts 3–4 times per week, adjusting the intensity or rest periods as needed to suit your comfort level and training experience.
Additionally, proper nutrition and hydration are crucial for supporting muscle growth. Consuming a balanced diet rich in protein can provide the necessary building blocks for muscle repair and growth. Staying hydrated also plays a vital role in muscle health and performance, ensuring your body can effectively repair and build muscle tissue.
In conclusion, high-intensity, short-duration running, when combined with a balanced diet and adequate hydration, can effectively build muscle, particularly in the lower body. By incorporating HIIT principles into your running routine and focusing on exercises that target the quadriceps and hamstrings, you can promote muscle growth and improve your overall fitness.

Long-distance running can damage muscle growth
Long-distance running can be beneficial for muscle growth in the lower body, but it depends on the intensity and duration of the runs. While running is an excellent form of aerobic exercise, it can also hinder muscle growth if not approached thoughtfully.
High-intensity, short-duration running workouts like HIIT (High-Intensity Interval Training) can effectively build lower body muscle, particularly in the quadriceps and hamstrings. This type of training involves short bursts of running at a near maximum capacity, followed by active recovery periods. For example, performing 45-second sprints at moderate intensity, separated by 5 minutes of walking or light jogging, can stimulate muscle growth.
However, long-distance running can have a different effect on the muscles. While it can build muscle to some extent, it can also lead to significant muscle damage. A study on male amateur runners found that those who ran longer distances experienced increased markers of muscle damage, which remained elevated even three days after their run. The levels of these markers rose with the distance covered, indicating that long-distance running can hinder muscle growth by causing muscle protein breakdown (MPB).
Additionally, long-distance running may increase appetite, leading to potential overconsumption of calories, which can further hinder muscle growth if not managed properly. It is important to note that muscle growth occurs when muscle protein synthesis (MPS) exceeds MPB. Therefore, finding the right balance between running and adequate nutrition is crucial for supporting muscle growth.
To optimize muscle growth while incorporating long-distance running into your routine, consider the following:
- Include high-intensity intervals within your runs: Incorporating short bursts of higher intensity running into your long-distance runs can stimulate muscle growth. For example, you can include intervals of faster running within your run, followed by a slower recovery pace.
- Focus on adequate nutrition: Ensure you are consuming enough high-quality protein to support muscle growth and repair. Aim for 0.64-0.91 grams of protein per pound of body weight daily. Include lean protein sources such as chicken breast, turkey, fish, or tofu.
- Manage your calorie intake: Long-distance running can increase appetite, so be mindful of your calorie intake. Ensure you are in a slight calorie deficit or maintenance mode, depending on your overall goals.
- Incorporate strength training: Include strength training exercises such as deadlifts, squats, or lunges into your routine to target multiple muscle groups and enhance overall muscle growth.

Running and nutrition for muscle building
Running can be an excellent form of exercise to build muscle, but it depends on the type of running you're doing. High-intensity, short-duration running, such as sprinting or HIIT workouts, can effectively build lower body muscles, particularly in the quadriceps and hamstrings. On the other hand, long-distance running can hinder muscle growth by increasing muscle protein breakdown (MPB). Therefore, if your goal is to build muscle through running, focus on high-intensity, short-burst exercises rather than long-distance runs.
Now, let's discuss the role of nutrition in muscle building for runners. Proper nutrition is crucial for anyone who runs regularly, whether it's a casual jog or an intense training regimen. A good diet can boost your physical health and help you meet your fitness goals, including building muscle. Here are some key nutritional considerations for runners aiming to build muscle:
- Carbohydrates: Carbohydrates are the cornerstone of a runner's diet. They are broken down into glucose, which is the primary source of energy for the body. Aim to get 60% to 70% of your calories from carbohydrates.
- Lean Protein: Include lean protein sources such as fish, poultry, beans, lentils, and tofu in your diet. Protein is essential for muscle building as it provides the amino acids that form the building blocks of muscles.
- Healthy Fats: Choose good fats over saturated varieties. While fats have a high energy value, they should be avoided as an immediate pre-run fuel source as they slow down digestion.
- Vitamins and Minerals: Ensure you're getting enough fruits and vegetables in your diet to provide essential vitamins, minerals, and antioxidants. This is crucial for overall health and can impact your running performance.
- Sodium: Sodium imbalance is a common issue for runners, leading to gastrointestinal distress, nausea, bloating, and fatigue. It is recommended to take 700-900mg of sodium per hour during longer runs or races to maintain proper sodium levels in the body.
- Hydration: Proper hydration is crucial for runners to avoid issues related to dehydration, such as gastrointestinal distress and impaired concentration.
Remember, the specific nutritional needs of each individual may vary, so it's important to listen to your body and adjust your diet accordingly. The key is to provide your body with the fuel it needs to support both your running regimen and your muscle-building goals.

Running and lifting weights
Running and weightlifting are two very different forms of exercise, but they can be combined effectively with a thoughtful approach. Running is excellent for cardiovascular health and endurance, while weightlifting is ideal for building strength and muscle mass. Both have unique benefits, and when combined, they can lead to a more balanced and robust physique.
When integrating running and weightlifting into your fitness regimen, it is important to develop a structured schedule that considers the intensity and impact of each workout. For example, pairing a high-intensity interval run with a lighter lifting session can enhance muscle recovery. Conversely, focusing on upper body or core weightlifting after a high-intensity run can prevent overtaxing the leg muscles. It is also crucial to prioritize recovery by including rest days, adequate sleep, and practices like foam rolling or massage to aid in muscle recovery.
Runners who lift weights have better running form and are less prone to injuries. Weightlifting helps to build running-specific muscles, such as stronger calves, which can lead to more explosive propulsion and faster running performance. Additionally, putting more muscle on your bones can help reduce the impact of repetitive running motions, providing a break for your bones and joints.
To effectively combine running and weightlifting, it is recommended to vary the intensity and volume of training through periodization. As you get stronger and fitter, gradually increase the intensity and duration of both your runs and weightlifting sessions. It is also important to listen to your body and be mindful of the signs of overtraining, such as consistently high levels of fatigue or nagging aches and pains. Incorporating flexibility and mobility work, such as yoga, can also enhance recovery and improve your range of motion, leading to better running form and lifting technique.
