When is dynamic stretching typically performed?

Dynamic stretching is typically performed prior to exercise because it serves to prepare the body for physical activity by increasing blood flow to the muscles, enhancing flexibility, and improving overall range of motion. This type of stretching involves movements that resemble the activity that one will be doing during the workout, which helps in activating the muscles and preparing them for the demands of exercise.

Engaging in dynamic stretching before a workout can also help to improve performance and reduce the risk of injury, as it gradually raises the heart rate and primes the nervous system. The movements utilized in dynamic stretching, such as leg swings, arm circles, or lunges, mimic the skills or motions involved in specific sports or fitness activities, making it a functional warm-up routine.

The other options are less appropriate because dynamic stretching is specifically designed to warm up before the main physical activities commence, rather than post-exercise, during workouts, or on rest days when the intention is usually to recover rather than prepare.
