What is defined as a brief period of exercise preceding a workout?

The phase referred to as a brief period of exercise preceding a workout is known as a warm-up. This is a crucial part of any fitness routine as it prepares the body for more intense activity. A warm-up typically involves light physical activity that gradually increases in intensity, helping to raise the heart rate, improve blood flow to the muscles, and enhance flexibility. By engaging in a warm-up, individuals can reduce the risk of injury and optimize their performance during the main workout.

The cooldown is a separate phase that occurs after the main workout, where the body gradually returns to its resting state. The main workout is the core part of the exercise session where the primary training occurs. Lastly, the recovery phase refers to the period after the workout where the body heals and adapts to the stress of the exercise. Each of these components has its specific function and timing within a workout regimen, but it is the warm-up that is specifically defined as the preparatory activity done right before engaging in the main exercises.
