In a seated position, the soleus muscle is primarily engaged during calf raises. The soleus is located beneath the gastrocnemius and is responsible for plantar flexion of the foot at the ankle joint, particularly when the knee is flexed. When seated, the gastrocnemius muscle is less active because it crosses both the knee and ankle joints, and its effectiveness is diminished due to the bent knee position. This makes the soleus the main muscle working during seated calf raises, as it can contract effectively in this position to elevate the heel while the knee remains flexed.

The other muscles mentioned, such as the peroneals and the flexor hallucis longus, play different roles in ankle and foot movement but do not contribute significantly to the movement during seated calf raises.
