This segment increases flexibility with Proprioceptive Neuromuscular Facilitation (PNF) techniques which may offer a superior mode of stretching because it facilitates muscular inhibition. Perform hold-relax techniques in this segment by pre-stretching a tight muscle for 10 seconds. Following, the stretched muscle is isometrically contracted in a hold position of resistance for six seconds before passively stretched for thirty seconds. Read more about this technique.
