Me but make sure you give me the right answer : )

It is not representative of the whole school because you asked only peple at the gym
what if there happened to be 1 person at the gym,
therfor you conclude that 100% of people at school exercise?
rediculus

1. no, becuse yo only asked peple at gym who are probaly exercising or pretenitng to exercise or showing off

2. yes, at the doors of the school or the school cafeteria or where there is a mixed group of people, the more the better, if you can survey the entire school, great

3. that is an either or situation, also people don't like to be called a couch potato so theere will be some people who will lie and say they exercise every day and there will be some peple wo don't want to answer and there will be some who will think you are insulting them and punch you
you will have biased results since you changed the question to the extermes

1. No, the results will only represent how much exercise those people do. 2.A better location would be somewhere like a playground because everyone goes there. At a gym you will only talk to people who do exercise. 3. The results of you answer would be different because there is less of a range of answers. People who don't exercise every day would have to go with the second answer even if they exercised on like 5 days a week. Without those answers you could say that they exercised a lot.
