Explain the difference between a static and dynamic stretch, and when each type might be more appropriate within a yoga practice.

Static stretching and dynamic stretching are two distinct types of stretching techniques, each with its own characteristics, benefits, and appropriate applications, especially within a yoga practice. Understanding the differences between these two can help yoga teachers and practitioners design more effective and safe routines. Static stretching involves holding a stretch in a stationary position for a period of time, typically ranging from 20 to 60 seconds. The muscles are lengthened and held at their maximum range of motion, often without any movement. The goal is to lengthen the targeted muscle and improve its flexibility by gently increasing the range of motion at a particular joint. In static stretching, there is no active engagement of the muscles involved other than to maintain the position. Examples of static stretches commonly used in yoga might include holding a hamstring stretch by extending one leg forward and reaching towards the toes, maintaining a long forward bend (Uttanasana) for a long time, or holding a deep lunge (Anjaneyasana) with the back knee on the ground for an extended time.
