Ana wants to increase the range of motion in her shoulder muscles. which of these provides the best cool down strategy for reaching that goal using static stretching? slowly extending stretches until the muscle hurts gradually increasing the challenge level of stretches quickly swinging the arms back and forth for more stretch intensely holding stretches for five to 10 seconds

Gradually increasing the challenge level of stretches

Explanation:

The best thing Ana should do to achieve her goal is to increase the overload principle, which is a principle that states that the intensity of training should be gradually increased. This means that in order to improve, athletes must work harder and harder as their bodies adjust to existing workouts.

Overloading explores the body's mechanisms that bring about the desired changes that go hand in hand with specificity. Increasing endurance requires lifting progressively heavier loads and practicing the sport in question more intensely.

With the progressive increase in training, Ana will be able to increase the range of motion in the shoulder muscles without overloading her.
