What type of stretch is exemplified by "arm swings"?

The example of "arm swings" is best categorized as a dynamic stretch. Dynamic stretching involves moving parts of your body and gradually increasing reach, speed of movement, or both. This type of stretching is typically performed in a controlled manner and is often used as part of a warm-up routine to prepare the muscles for more intense activity.

Arm swings allow the shoulder joints to loosen up and the muscles around them to engage in a manner that mimics the motions you will perform during your workout or sport. This helps to increase blood flow and improve functional mobility, making it an effective way to warm up large muscle groups.

In contrast, static stretching involves holding a position for a set amount of time, isostatic stretching involves a combination of isometric contractions followed by passive stretching, and ballistic stretching consists of bouncing movements to push the body beyond its normal range of motion, which can be riskier and is generally not recommended for most warm-up routines.
