This is an interesting question because what you experience as “tight fascia” may involve a combination of muscles, connective tissue and the way your body is moving.
Previous injuries, repetitive activity, long periods in one position and changes in training may all contribute to feelings of stiffness or restriction.
Sometimes the area that feels tight isn’t the whole story either.
That’s why I’ll assess your movement rather than simply pressing on the sore spot and assuming we’ve found the answer.
Bodies are wonderfully complicated like that.
