This month's article is part two in a two-part series on dynamic stretching.  Part one covered static, ballistic and one variation of dynamic stretching.  The second type of dynamic stretch is more active than the first and has become one of the preferred methods of stretching.

First, let's review briefly the different types of stretching and the basic definition of dynamic stretching: 

Static stretching is the common type of stretching that most athletes perform. Static stretching is where the body is placed in a position and held for a set amount of time, typically 10 to 30 seconds.   

Ballistic stretching is what we think of when we imagine what they did in the "old days" before they knew better.  Ballistic stretching involves forcefully stretching a muscle repeatedly over a set amount of time.  For example, one might bend over with the legs straight and attempt to "bounce" down to touch the floor.  These types of stretches can likely lead to injury and are typically discouraged.

Dynamic stretching could be considered a combination of the two other types but is distinctly different in its outcome.  Dynamic stretching focuses on multiple muscle groups versus one and typically is specific to a sport movement.  Last month we covered one type of dynamic stretching, and this month we will cover another.
