Answer: All of the above.
Step-by-step explanation:
The stretching is an act of healing the scars and the scar tissues that will help to increase the mobility of the body. Various stretching and flexibility exercises helps to line up, lengthen and stretch the impacted tissues that are found near the scar, which are typically the myofibrils. If the tissue fibers are elongated and not much tight and rigid, then the body will experience less restriction and better mobility. Thus the scars on the muscles are removed.
