Partner PNF (Proprioceptive Neuromuscular Facilitation) is a stretching technique that combines muscle contraction and relaxation to safely increase range of motion. It involves lengthening a muscle, then contracting it isometrically against resistance, followed by a deeper stretch. This works through the body’s proprioceptors, sensory receptors in the muscles and tendons that monitor tension and length. When a muscle contracts, the Golgi tendon organs signal the nervous system to allow the musc
