Techniques to enhance flexibility include static stretching, dynamic stretches, and proprioceptive neuromuscular facilitation (PNF). Static stretching involves holding a stretch position for an extended time, promoting muscle lengthening. Dynamic stretches incorporate movement and are typically performed before workouts to prepare muscles for action. PNF combines stretching and contracting muscles to achieve greater range of motion. Incorporating these techniques into a regular fitness routine can improve flexibility, contributing to better overall physical performance and reducing injury risk.
