Refutation and Cncession

Refutation and Concession :

what is my thesis?

Exercise has positive effects on human mind.

What is the opposite position?

Doing exercise only effects on human body not the brain.

What arguments can I anticipate?

 ex) there is saying that the men who exercise a lot are cool but fool.

How I counter those arguments?

The saying is just a prejudice and generalization. And I mean moderate exercise. Not the professional athletes.

My refutation and Concession

Although there are a lot of studies that prove my arguments, there are some opponents who argue that doing exercise only effects on human body not the brain.

They are saying that how physical activity can affects the inner organization called brain. And also they use the saying that the men who exercise a lot are cool but fool.

However, I insist that the exercise can effects on human brain. I've already said that doing exercise trigger the gene expression that is associated with hippocampus which enhance the memory power. Also the saying that the men who exercise a lot are cool but foo is just a a prejudice and generalization. And I mean basic moderate exercise not the professional sports.

Also I want to insist that always there are some exception.
