Which muscle is primarily targeted during the seated calf raise exercise?

The seated calf raise exercise primarily targets the soleus muscle. The soleus is located beneath the gastrocnemius and is an essential muscle for plantar flexion of the ankle, especially when the knee is bent, as it is in the seated position. This position effectively isolates the soleus by reducing the involvement of the gastrocnemius, which is more engaged when the knee is straight. The seated calf raise emphasizes the strength and endurance of the soleus, making it highly effective for developing the muscles involved in activities that require balance and powerful ankle movements.

In this exercise, the soleus also plays a critical role in standing postural stability and is crucial for activities such as walking, running, and jumping, where a strong and well-conditioned soleus can enhance performance and reduce the risk of injury. Therefore, this makes the soleus the primary target of the seated calf raise, distinguishing it from the other muscle options listed, which do not share the same primary role in this particular movement.
