The soleus muscle is a wide, flat muscle in the calf that is responsible for pointing the toes downward and maintaining posture and balance. It is also the main plantar flexor muscle, generating the majority of the mechanical work through active shortening. This means that the soleus is very important for athletes, especially those who specialize in long-distance and endurance running or walking. As such, it is important to know how to shorten the soleus muscle to improve its function and prevent injury.

Soleus pushup
The soleus muscle in the calf can have a significant impact on improving the metabolic health of the body if activated correctly. The soleus pushup (SPU) is a type of exercise that can be done while sitting and can elevate muscle metabolism for hours. It is a potent physiological movement that capitalizes on the unique features of the soleus.
The soleus pushup was developed by Marc Hamilton, professor of Health and Human Performance at the University of Houston, along with his colleagues. The SPU targets the soleus to increase oxygen consumption more than what is possible with other types of soleus activities, while also being resistant to fatigue. The soleus is a posterior leg muscle that runs from just below the knee to the heel and is one of 600 muscles in the human body.
To perform a soleus pushup, sit in a chair with your knees bent and your feet flat on the floor. Push your toes into the ground as you raise your heels. When your heels get to the top of their range of motion, lower your heels and repeat. The aim is to simultaneously shorten the calf muscle while the soleus is naturally activated by its motor neurons. The movement might look similar to walking, but it is the exact opposite, according to researchers. When walking, the body is designed to minimize the amount of energy used, due to how the soleus moves.
The soleus pushup has a relatively low energy expenditure as it uses a muscle that makes up only one percent of total body mass and burns fewer calories per minute than walking. However, researchers found that it boosted metabolism and improved glucose regulation. Participants who performed soleus pushups saw elevated whole-body metabolism levels and a 52% improvement in blood sugar regulation after drinking a glucose drink.

Soleus stretches
The soleus muscle is a posterior leg muscle that runs from just below the knee to the heel. Stretching and activating the soleus muscle can improve metabolic health and blood glucose regulation in the body.
A soleus stretch targets the lower leg muscles to promote flexibility and function. It helps to improve ankle flexibility and reduce calf tightness, which can help prevent injuries and make physical activities easier.
To perform a basic soleus stretch:
- Stand with your feet hip-width apart.
- Keep your knees straight.
- Lean forward, keeping your heels on the ground, and stretch the calves.
- Hold this position for 15-30 seconds.
- Relax and repeat as needed.
The Soleus Pushup:
The Soleus Pushup (SPU) is a type of movement that specifically targets the soleus muscle. It is performed while seated and helps to increase oxygen consumption and is resistant to fatigue. Here's how to do it:
- Sit with your feet flat on the floor and muscles relaxed.
- Raise your heels while keeping the front of your feet on the ground.
- When your heels reach the top of their range of motion, slowly lower them back down.
- Repeat this movement to activate the soleus muscle and improve metabolic function.
It is important to note that you should not bounce while stretching and always listen to your body to avoid injury.

Soleus tear treatment
The soleus muscle is located deep in the calf and is responsible for pushing off the ground when walking, running, or jumping. It is also crucial for maintaining balance. Tears in the soleus muscle can occur due to sudden forceful actions like jumping or abrupt stops during sports. These tears can cause intense pain and difficulty in calf movement.
If you suspect a soleus tear, it is important to seek medical attention to confirm the diagnosis and rule out other conditions. Your doctor may recommend an ultrasound or an MRI scan to check for muscle tears and internal bleeding.
Once a soleus tear is confirmed, treatment options are available to facilitate healing and relieve symptoms:
Rest
It is crucial to stop any physical activity that causes pain and allow the calf muscle to rest. You may need to use crutches or wear a boot for several days to avoid putting weight on the injured leg.
Ice
Applying ice packs or cold compresses to the affected area for 15-20 minutes every few hours during the first two days can help reduce inflammation and pain.
Compression
Wrapping the calf with a medical bandage can provide mild compression, which helps prevent swelling and provides support to the injured muscle.
Elevation
Keeping the injured leg elevated above the heart level can further reduce swelling and promote healing by improving blood flow to the area.
For severe tears or when non-surgical treatments are ineffective, surgery may be considered. During surgery, the surgeon makes an incision in the calf and reattaches the ruptured muscle ends with stitches. This is usually followed by a cast for several weeks, after which physical therapy may be recommended to restore strength and flexibility to the calf muscle.
To prevent soleus tears, it is essential to warm up properly before workouts, focusing on calf muscle stretches. Gradually increasing activity intensity and avoiding sudden increases in distance or weight can also help prevent overload and reduce the risk of injury.

Soleus and gastrocnemius
The calf muscle is made up of two main muscles: the gastrocnemius and the soleus. Together, these muscles help us walk, run, jump, stand on our toes, and flex our feet. The gastrocnemius is the larger calf muscle that runs from the back of the knee down to the Achilles tendon. It is close to the skin's surface, so you can often see its outline. The soleus is a wide, large, and flat muscle that sits slightly deeper than the gastrocnemius. It runs from just below the knee to the heel.
The gastrocnemius and soleus muscles are both susceptible to strains, which are common injuries. Strains of these muscles can be differentiated through clinical testing, including palpation, strength testing, and stretching. The physical examination is key to determining the site of injury and guiding rehabilitation.
The soleus muscle is also known as the "most important" muscle in the body by some researchers. This is because, when activated correctly, it can improve metabolic health and elevate muscle metabolism for hours, even while sitting. A technique called the soleus pushup has been developed to target the soleus muscle and increase oxygen consumption. This movement is designed to be performed while seated and involves raising the heel while keeping the front of the foot on the floor.
To improve the flexibility and function of the soleus muscle, a stretch called the "soleus stretch" can be performed. This stretch targets key muscles in the lower leg to promote better flexibility and function, improve ankle flexibility, and reduce calf tightness.

Soleus and metabolic health
The soleus muscle, found in the calf, is one of the 600 muscles in the human body. It is a posterior leg muscle that runs from just below the knee to the heel. The soleus is responsible for pointing the toes downward and helps maintain posture and balance when standing and doing slower, controlled movements.
Research has shown that the soleus muscle can significantly improve metabolic health in the body if activated correctly. For instance, the soleus pushup (SPU) developed by Marc Hamilton, a professor of Health and Human Performance at the University of Houston, effectively elevates muscle metabolism for hours, even while sitting. The SPU targets the soleus to increase oxygen consumption while also being resistant to fatigue.
The SPU involves a specific movement that requires the feet to be flat on the floor while seated and the muscles relaxed. The heel is then raised while the front of the foot stays on the ground. When the heel reaches the top of its range of motion, the foot is passively released to come back down. This movement simultaneously shortens the calf muscle while the soleus is naturally activated by its motor neurons.
The soleus muscle has the potential to contribute to systemic metabolic regulation, as evidenced by studies. For example, a 2022 study found that the human soleus muscle could elevate local oxidative metabolism for hours during a type of soleus-dominant activity while sitting, even in unfit volunteers. This suggests that the soleus muscle can improve metabolic health, particularly in individuals with a sedentary lifestyle.
