I will teach you how to negate sentences ('not').
You have options either adding '안' before verbs or adding '지 않다' after verb roots.
1) 안 + verbs
Here is the thing,
if you use '하다'(do) ending regular verbs, you could often break 'N + 하다'.
For example, '운동하다' is a combination of '운동' and '하다'.
In this case, it's better if you put '안' negation between the noun and 하다.
