A teacher prepares a lecture on the benefits of exercise. which of these will it not highlight?

The answer to this question would be: Exercise provides decreased warmth and body arousal.

Exercise can give much benefit. By doing exercise regularly, you can boost your mood, increase your cognitive ability and also promote the growth of the brain cells. Exercise also increases your heart capacity so it can do much more work. But it won't decrease body warmth as the muscle used will produce heat, not decrease it.
