Leg Stretching - Tibial Flexion With Semi-flexed Knee.
Muscles involved: Soleus
Standing and holding on to a support, push one leg backward and – with the knee semi flexed – plant the entire sole of the foot on the ground in such a way that the tension is felt in the area of the soleus (below the gastrocnemius). The forward leg remains in semi-flexion, supporting the weight of the body.
The important thing in this exercise is to keep the knee in flexion, to place more emphasis on the stretching of the soleus. The point of maximum stretch is achieved, by gently placing the heel of the back leg on the ground. The most common way of adjusting the tension over the soleus is to gradually bring the knee closer to the wall without lifting the heel off the ground.
