Running is a high-intensity activity that engages multiple muscle groups and gets your heart rate up. It is a form of cardiovascular exercise that increases heart rate and boosts metabolism, aiding in weight loss. Running works your legs, including the quads, hamstrings, and calves, as well as your hips and glutes. Your abdominal muscles, inner thighs, and shoulders also get a workout, but the large muscles of your hips and legs do most of the work. The degree of muscle engagement depends on your speed and terrain. For example, running downhill demands more from your quadriceps as they have to perform strong eccentric contractions to control your speed.

What You'll Learn
Hip flexors, quads, and hamstrings
Running is a complex movement that requires many parts of the body to work in unison, from the feet to the core to the arms and legs. Hip flexors, quads, and hamstrings are key muscle groups that are activated during running.
The hip flexors are a group of muscles and tendons located at the front of the hip joint, linking the legs to the pelvis. They influence the movement between the torso and legs, affecting the smoothness of the stride. Tightness in the hip flexors can limit the range of hip extension, reducing the contribution of the glutes during running. To prevent this, it is important to include hip flexor stretches and mobilisation exercises in your routine. Additionally, strengthening the hip abductors, such as the Gluteus Medius, can improve hip biomechanics and reduce the strain on the hip flexors.
The quadriceps, or quads, are a group of four muscles in the front of the thigh. They play a crucial role in bending the hip when lifting the knee and straightening the knee during the foot strike. While quads are essential for generating power, excessive quad-dominance can lead to injuries such as Runner's Knee, shin splints, and knee osteoarthritis. To optimise running form and reduce the risk of injuries, it is important to focus on achieving a balanced engagement of the glutes and quads. This can be encouraged through movements and cues that promote a "Push. Don't Pull." mantra, emphasising the use of the backside muscles to propel the body forward.
The hamstrings are comprised of three muscles located at the back of the thigh. They work in tandem with the quadriceps, contracting and stretching to control the forward motion of the knee and pull the leg into the foot-strike position. Strong hamstrings are beneficial for runners as they help prevent injuries and improve running performance. To strengthen the hamstrings, exercises that load the hamstrings during stretching and contraction are recommended. For example, slowly leaning forward until you feel the hamstrings engaging, and then gently catching yourself with your hands.

Calf muscles
Running is a great way to tone your calf muscles, along with your quads, hamstrings, and glutes. The calf muscles are located on the back of your lower leg and are used to propel you forward when you run. They are also responsible for reducing the shock of impact as you land, helping with balance, and ankle mobility.
To tone your calf muscles, you can try classic exercises such as calf raises. These exercises strengthen and tone the gastrocnemius and soleus muscles. They can be done anywhere and don't take a lot of time. Simply stand with your feet hip-width apart, and press down into the balls of your feet to raise your body upward.
You can also try dynamic plyometric movements or sports such as soccer, basketball, and tennis, which will strengthen your calves over time. Swimming is another excellent option, as it works your calves while being low-impact.
If you're looking to tone your calves through running, you can try running uphill. The steeper the incline, the more your calf muscles have to work. Just remember that running will only build muscle to a certain point, and strength training exercises may be necessary to see more significant results.

Gluteal muscles
The gluteal muscles are located in the buttocks and play a vital role in running. They are responsible for hip extension, which propels the body forward with each stride. The gluteus maximus is the largest and most powerful of the three gluteal muscles, and it is crucial for extending the hip joint. Going uphill or running at faster paces requires more engagement from the gluteus maximus.
The gluteus medius and minimus contribute significantly to stability and balance during running. These muscles stabilize the pelvis, preventing excessive lateral movement and maintaining alignment, which is crucial for injury prevention. Weak gluteal muscles can lead to injuries, such as IT band syndrome, patellofemoral knee pain, and foot and ankle problems.
To strengthen the gluteal muscles, targeted exercises such as squats, lunges, hip bridges, and lateral band walks can be incorporated into a training routine. Running uphill is also an effective way to build gluteal strength.
Overall, the gluteal muscles are essential for maintaining proper running form, stability, and forward propulsion. By strengthening these muscles and incorporating cross-training activities, runners can enhance their endurance, balance, and overall performance while reducing the risk of injuries.

Abdominal muscles
Running is a great way to tone your abdominal muscles. While it won't give you a six-pack, it will strengthen and tone your abs and help burn fat around your midsection. Each stride you take while running requires the effort of several muscles, and your abdominal muscles play a supporting role in your running cadence. These muscles hold your torso upright, helping you to avoid back pain. As running causes a significant amount of spine movement, strong abdominal muscles can also stabilise your spine and pelvis, preventing injury.
The muscles in your abdomen link your upper and lower body. While running, they stabilise your pelvis and spine, allowing you to move your legs more efficiently and preventing your body from twisting back and forth, which would waste energy. Your abdominal muscles also engage during the stance phase when you shift your weight onto one leg, creating stability so that you don't fall to one side when lifting a leg. They work extra hard to limit trunk rotation during sprints, as the faster speed demands more from these muscles to stabilise.
The core includes the transversus abdominis, a deep layer of muscle that stabilises the spine; the multifidus, a group of small muscles alongside the spine that also help with stabilisation; the internal and external obliques, which help flex and rotate the trunk; the erector spinae, three long muscles along the spine which help straighten and rotate the back; the diaphragm, which raises and lowers the ribs as you breathe; and the pelvic floor muscles, which support and stabilise the pelvis and spine.
To maintain maximum efficiency as a runner, it's important to have strong abdominal muscles, as well as flexible hamstrings. Otherwise, your form suffers, and your risk of pain and injury increases. Running will strengthen your abdominal muscles to a certain point, but to build muscle further, strength training will be more effective.

Shoulder muscles
Running is a full-body workout, but it primarily engages the core and lower-body muscles. However, the shoulder muscles are also involved, and they can be affected by running in various ways.
The shoulder joint, clavicle, and thoracic spine are less frequently associated with running-related pain, accounting for about 4.8% of total complaints among runners. Nevertheless, shoulder pain can significantly impact a runner's performance and enjoyment.
The upper trapezius, deltoids, and rotator cuff are specific shoulder muscles that may experience discomfort during or after a run. Poor posture, such as rounding the shoulders, hiking them up, or leaning the head forward, can cause these muscles to ache. This improper positioning overworks the upper trapezius and levator scapulae, leading to pain.
Additionally, tightness in the chest muscles, such as the pectoralis major, can pull the shoulders forward, further exacerbating poor posture issues. The pectoralis minor may also be over-engaged due to aggressive arm movements across the body.
To prevent shoulder pain and tension, it is crucial to maintain proper running form and posture. This includes keeping your shoulder blades back and down, chest up, eyes forward, and neck in line with the spine. Practicing good posture in daily life and incorporating exercises that work the upper body, such as bent-over rows and push-ups, can also help improve running posture.
Furthermore, focusing on smooth, rhythmic breathing patterns and consciously relaxing the shoulders and arms during runs can help prevent unnecessary shoulder tension. Runners should also be mindful of their overall relaxation while running to avoid overworking the shoulder muscles.
While some cases of shoulder pain can be managed with adjustments, persistent or severe pain, or symptoms like swelling and redness, may require medical attention.
