Question

why should intense stretches be saved for the end of a workout?
stretching is never important before a workout.
intense stretching takes too much time to include in a warm - up.
none of the above
there is less risk for injury because muscles are more pliable when warm, such as at the end of a workout.

Explanation:

Muscles are more flexible and less likely to be injured when they are warm, which occurs at the end of a workout. Stretching is important before a workout (in the form of light - dynamic stretching), and time is not the main reason for saving intense stretches for the end.

Answer:

There is less risk for injury because muscles are more pliable when warm, such as at the end of a workout.
