What is one potential consequence of not warming up before exercise?

Not warming up before exercise can significantly increase the risk of injury. When a person engages in physical activity without proper preparation, their muscles, ligaments, and tendons are cold and less pliable. This lack of flexibility can lead to strains or sprains, as the body is not adequately prepared for the demands of exercise. Warming up increases blood flow to the muscles, raising their temperature and enhancing elasticity, which helps to prevent injuries.

Additionally, warming up gradually prepares the cardiovascular system for the upcoming aerobic or muscular activity, thereby improving performance and safety. The other options, such as increased flexibility, enhanced mental focus, and improved cardiovascular health, are benefits typically associated with proper warm-up routines, rather than consequences of neglecting to warm up.
