Final answer:
The three stages of an exercise session are warm-up, workout, and cool-down.
Step-by-step explanation:
The three stages of an exercise session are warm-up, workout, and cool-down. Warm-up is the initial phase of an exercise session that involves light physical activity to prepare the body for more intense exercise. It helps increase heart rate, improve blood circulation, and warm up muscles. Workout is the main part of the exercise session where the body is engaged in moderate to high-intensity physical activity. It can include various exercises such as aerobic exercises, strength training, or sports-specific drills. Cool-down is the final phase of an exercise session where the body gradually returns to its resting state. It involves light exercise or stretching to help prevent muscle soreness and promote recovery.
