What You'll Learn
High-intensity interval training (HIIT) can build leg muscles
Running is an excellent form of exercise for improving cardiovascular stamina, reducing the demand on the lungs, and enabling the body to use energy more efficiently. It can also help build lower body muscles, but this depends on the intensity and duration of the runs.
High-intensity interval training (HIIT) is a workout strategy that involves short bursts of intense exercise, followed by low-intensity recovery periods. HIIT workouts can be completed in a short amount of time, making them a time-efficient way to exercise. They are designed to burn fat and build muscle fast by stressing muscles more than other workouts.
HIIT can be a great way to build leg muscles, especially in the quadriceps and hamstrings. In one study, participants who completed a 10-week HIIT program involving high-intensity running showed an 11% increase in the muscle fiber area of their quadriceps compared to a control group.
To build muscle through HIIT, it is important to have proper form and preparation. HIIT workouts can lead to muscle and joint injuries if not done correctly, so it is important to start slowly and increase the intensity gradually. Additionally, good nutrition is essential for building muscle. Consuming adequate protein is crucial, as it enhances the muscle-building process.

Long-distance running can cause muscle damage and hinder growth
Running is a popular form of exercise, often taken up to improve health, reduce stress, or compete in races. While it is an excellent way to boost cardiovascular stamina and energy levels, the impact of long-distance running on muscle growth is more complex.
However, it is important to note that the impact of running on muscle growth depends on the intensity and duration of the runs. High-intensity, short-duration running, such as sprinting or high-intensity interval training (HIIT), can effectively build lower body muscles. This type of training stimulates muscle growth by increasing muscle protein synthesis (MPS) and promoting muscle fiber growth, particularly in the quadriceps and hamstrings.
To support muscle growth and prevent damage, it is crucial to incorporate weight training and consume sufficient protein. Protein is essential for the muscle-building process, as it enhances muscle protein synthesis. Experts recommend consuming 0.64–0.91 grams of protein per pound of body weight daily to support muscle growth. Additionally, proper footwear and knee support can help reduce the impact of running on the joints and prevent injuries.
While long-distance running may hinder muscle growth, it offers various other benefits for the body. It improves cardiovascular health, enhances energy efficiency, and promotes better sleep. Therefore, for those looking to build muscle, a balanced approach that includes a mix of high-intensity interval training, weight training, and adequate protein intake can support muscle growth while still enjoying the benefits of long-distance running.

Running can help lose fat while retaining muscle
Running is a great way to lose fat while retaining muscle. It is an aerobic exercise that can build muscle by inhibiting proteins that interfere with muscle growth and decreasing muscle protein breakdown (MPB). Running also stimulates muscle protein synthesis (MPS), which is key to muscle building.
However, it is important to note that the type of running and the intensity of the workout can have varying effects on muscle retention. While high-intensity, short-duration running can build muscle, long-distance running can significantly increase MPB, hindering muscle growth. This is because long-distance running can cause significant muscle damage, and the markers of this damage can remain elevated even three days after a run. Therefore, it is recommended to focus on high-intensity interval training (HIIT) workouts, such as sprinting, to promote muscle growth while losing fat.
To ensure muscle retention while running, it is crucial to consume sufficient protein. Protein enhances the muscle-building process, promoting greater muscle gains. Experts recommend consuming 0.64–0.91 grams of protein per pound (1.4–2 grams per kg) of body weight daily. Good sources of protein include meat, poultry, dairy, fish, eggs, soy, beans, and legumes. Additionally, including weight training in your exercise routine can help add mass to your leg muscles.
Running also has other physical benefits. It improves cardiovascular stamina, reduces the demand on the lungs, and enables the body to use energy more efficiently. It can also help you get better sleep and rest, leading to increased energy during the day. Running is a great way to develop lean muscle in your legs and build endurance. However, it is important to take measures to protect your joints, such as your hips, knees, and ankles, from the impact of running.

Running builds endurance and lean muscle in legs
Running is an excellent form of exercise that offers numerous physical and mental health benefits. While it is typically associated with cardiovascular endurance, it can also help build lean muscle in the legs, particularly when combined with strength training and proper nutrition.
The physical act of running engages multiple muscle groups in the legs, including the quadriceps, hamstrings, glutes, and calves. These muscles work together to stabilise the body, absorb impact, and generate power during the running motion. Over time, with consistent training, these muscles can become stronger and more defined, leading to improved endurance and performance.
High-intensity interval training (HIIT) is a popular form of running that involves short bursts of intense effort followed by active recovery periods. Studies have shown that HIIT can effectively increase muscle growth, particularly in the lower body. In one study, participants who performed HIIT workouts three times a week for ten weeks experienced an 11% increase in muscle fibre area in their quadriceps compared to a control group.
Additionally, running promotes the development of local capillarization, which refers to an increase in the number of capillaries in the muscles. This enhanced network of small blood vessels improves blood flow and oxygen delivery to the muscles, allowing for greater endurance and potentially facilitating muscle growth.
However, it is important to note that running long distances can lead to increased muscle protein breakdown (MPB) and hinder muscle growth. Therefore, a balanced approach that includes adequate rest and recovery is crucial. Proper nutrition, particularly sufficient protein intake, is also essential for supporting muscle growth and preventing muscle loss during endurance training.
In conclusion, running can indeed build endurance and contribute to lean muscle development in the legs. When combined with strength training, proper nutrition, and adequate recovery, individuals can effectively enhance their muscle-building efforts and achieve their fitness goals.
