What are the types of flexibility exercise?

There are several types of flexibility exercises, including static stretching, dynamic stretching, ballistic stretching, and PNF (proprioceptive neuromuscular facilitation) stretching. Static stretching involves holding a stretch for an extended period to improve overall flexibility. Dynamic stretching incorporates movement and is often used as a warm-up to enhance range of motion. Ballistic stretching utilizes bouncing motions to push muscles beyond their normal range, while PNF stretching combines stretching and contracting of the muscle for increased flexibility.
