What is the primary goal of performing arm swings in defensive tactics practice?

Performing arm swings in defensive tactics practice primarily serves to enhance flexibility and warm up the shoulders. This is essential because flexibility in the shoulder joint is critical for executing a wide range of movements effectively in defensive scenarios. Warming up the shoulders helps prepare the muscles and joints for more intensive physical activity, reducing the risk of injury. Increased flexibility can also improve the overall range of motion, which is particularly beneficial in a defensive context where quick reactions and fluid movement are necessary. While arm swings might contribute secondary benefits to strength or endurance, their primary purpose is focused on flexibility and preparing the upper body for subsequent physical demands.
