What does PNF stretching aim to achieve?

PNF stretching, or Proprioceptive Neuromuscular Facilitation, is primarily designed to enhance flexibility through specific contraction-relaxation sequences. This technique involves a partner or therapist assisting the individual in stretching a muscle by first contracting that muscle isometrically and then relaxing it to allow for a deeper stretch. This approach takes advantage of the body's natural reflexes to improve range of motion and flexibility more effectively than static stretching alone.

While muscle hypertrophy, improved cardiovascular endurance, and increased coordination of movements are important aspects of physical fitness, they are not the main goals of PNF stretching. The focus is on how the neurological response to muscle contraction can help facilitate greater flexibility and optimize stretching outcomes.
