Proprioceptive neuromuscular facilitation (PNF) is a flexibility training technique that typically involves a partner who assists the individual in stretching. PNF utilizes both the contraction and relaxation of the muscle group being stretched, which often requires the active involvement of a partner. In this method, the individual will perform an isometric contraction of the target muscle followed by a passive stretch facilitated by the partner. This is effective because the isometric contraction can create greater relaxation in the muscle immediately following it, allowing for a deeper and more effective stretch.

In contrast, static stretching involves holding a stretch for an extended period without any partner assistance, making it less dynamic than PNF. Active isolated stretching is characterized by the use of specific muscle contractions to hold stretches for short periods, also typically performed without a partner. Myofascial release is a technique focused on relieving tension in the fascia and muscles through self-massage or with tools, not requiring a partner to assist with stretches.
