Overview
PNF (proprioceptive neuromuscular facilitation) stretching is a technique that uses alternating cycles of muscle contraction and relaxation to achieve deeper, more effective stretches. Originally developed for rehabilitation, PNF stretching is now widely used to improve flexibility in healthy individuals and athletes. These exercises typically involve holding a stretch, contracting the target muscle against resistance for a few seconds, then relaxing into a deeper stretch. A partner can help, but many PNF stretches can be performed solo using a towel or resistance band.
