What is myofascial release?
"Myo" refers to muscle, and "fascia" to the elastic web of connective tissue that spreads throughout your body and ties it together.  Muscles and fascia work together to support your body and facilitate movement.
Myofascial release is a hands-on technique involving the application of stretches and pressure to the fascia and muscles.  It relieves tension and pain by releasing and lengthening the fascia, which allows muscles to return to their correct position, length and function.
