Static stretching means a stretch is held in a challenging but comfortable position for a period of time, usually somewhere between 10 to 30 seconds. Static stretching is the most common form of stretching found in general fitness and is considered safe and effective for improving overall flexibility.
While static stretching takes a muscle to its full length and holds it there for 15 to 60 seconds, a dynamic stretch takes soft tissues to their full length and rather than holding it, after a brief pause of 3 to five seconds, the muscle being stretched contracts and the muscles and tendons exert a force in that lengthened position.
