@dr_nick_dpt_: The soleus muscle is the largest and most powerful muscle in the lower leg. It originates from the head of the fibula and soleal line of the tibia and inserts into the posterior calcaneus via the achilles tendon. Its action is to plantarflex the ankle and to stabilize the tibia when the foot is touching the ground. It is estimated to create as much as 80% of the force generated in the lower leg during plyometric activity. Try this soleus release and let me know how it goes for you! 💪🏼 #physicaltherapy #physio #physiotherapy #calf #anklepain #achilles #anatomy #physiology #kinesiology #plyometrics
