What should be avoided during a warm-up?

Avoiding lactic acid build-up during a warm-up is important because the purpose of this phase is to gradually increase the body's readiness for more intense physical activity. The warm-up is designed to enhance circulation, elevate muscle temperature, and prepare the cardiovascular system for increased demands. Ensuring that lactic acid does not accumulate is consistent with maintaining an aerobic state, which is ideal during the warm-up.

During a proper warm-up, the aim is to prepare the muscles and systems gradually without overexerting them. If lactic acid begins to build up, it indicates that the body's energy systems are shifting towards anaerobic metabolism, which is more intense and not suitable for this phase. Instead, the focus should be on encouraging a smooth transition into the main workout without incurring fatigue or excessive strain.

In summary, avoiding lactic acid build-up supports the physiological goals of a warm-up, ensuring that the body transitions safely and effectively into more challenging activities.
