What do Muscle Groups Running Work?

in this section, I will discuss the crucial role of running muscles or main muscles which are used in this complete body workout. All these key muscles work on your upper leg, hamstrings, quads, etc to make your body strong and injury-free during this training.

Hip Flexors Muscles

When you are running, every time you lift your thighs high, your hip flexors are used. When you raise your thighs to the level of your stomach, these muscles get stretched.

There are 5 main hip flexors muscle groups which are the Sartorius muscles, Psoas, Iliacus, Rectus Femoris, Iliocapsularis. All the hip flexor muscles are utilized when you do activities such as swinging, steps climbing, running, leg forward, and so on. Generally, they work in the combination with your thigh and abdominal muscles.

Calf Muscles

The calves are located just below and behind your knees region which are responsible for the movement of your toes. The calf muscles flex whenever you extend your toes. If you ever notice then the professional runners have fairly toned calves.

Besides, when you go for long runs, the calves tend to become sore. It gets toned by regular lifting work of the leg when you are running. Apart from this, they play a vital role to keep your legs and ankles free from sprains.

Abdominal Muscles or Abs

The abdominal muscles or abs are your core regions that are important for the harmonious functioning of all the muscle groups. Among all your abs, running strengthens and tone up the intercostals and rectus abdominis.

Here, the rectus abdominis is a cluster of long flat muscles that are along the center of your abdominal muscles and on the sides of your Abs. While the intercostal muscles are found between your ribs and these muscles do the running work.

They are useful when you need to do heavy inhalation and exhalation while running. Further, the abdominal muscles connect your lower body and upper body and keep your posture perfect and erect.

Above this, to strengthen your upper and lower body abdominal muscles, you have to maintain your posture while running longer distances. This practice prevents fatigue and uninvited injury too.

Glutes or Gluteal Muscles

These muscles are located in your buttocks that directly get affected while running. The glutes comprise 3 primary muscles namely: Gluteus minimus, Gluteus Medius, and Gluteus Maximus. Professional runners have experienced their glutes contracting when they run up or sit up.

In addition to this, the Gluteus maximus is the largest muscle present in your body. Further, gluteus medius and minimus are vital to stabilizing your legs and body while running. Many runners do some particular exercises to strengthen their glutes and hips.

Thigh Muscles

The thigh muscles include hamstrings and quadriceps. Further, the quadricep muscles include vastus medialis, vastus intermedius, vastus lateralis, and rectus femoris. Out of four muscles, 3 are attached to the kneecap right from the femur. While the rectus femoris connects from the hip to the kneecap.

Coming to the hamstrings, these muscles are located on the back of your leg and work the same as your biceps which contract whenever you fold your elbows. Basically, the hamstring muscles work whenever you extend or stretch your lower leg which is essential for swinging the leg forward and backward. So, all these muscles do the running work effectively.

Upper Body Muscles

Running primarily impacts the lower body, however, many runners know that the upper body automatically works out particularly your pectoral muscles and biceps. The shoulder muscles, also known as deltoids, experience an intense workout when these muscles get involved when runners swing their shoulders.

Besides, a strong abdominal is important to minimize the impact on your back and to keep your body upright. However, a weak core may force you to compensate with other body muscles which may lead to injury and pain.

Feet

The feet region comprises 4 layers of muscles. Out of 4, some start in the leg and connect to the feet whereas some originate in the feet themselves. To master your running skills, the combination of flexible ankle and strong feet along with the mobile hips do wonder.

Further, runners wear cushioned running shoes so their feet cannot utilize their capability in steadying the body weight. Also, overly rigid ankles lead to foot injuries as they pressurize the foot to take over the flexibility role.
