Gastrocnemius
Rolling and stretching of gastrocnemius is essential for the proper functioning of the ankle and knee joints. If it becomes too “strong”, it can cause a number of posture defects and consequent pain. (most often it causes the inflammation of the Achilles tendon)
It belongs to the *back muscle chain, so it is worth dealing with all the muscles of the chain, rolling, stretching.
Roll both sides of the gastrocnemius, stretch it.
The presented image and video material can be done for everyone, but in case of any injury, a consultation/survey is recommended for individualized training.
