Hi Darija, well, to complicate matters, I would write �push up � but I think any of those push-up, pushup or push up is fine, although pushup looks odd to me.
1. Have you ever engaged in any vigorous fitness activities?
2. Do you like (enjoy) going to the gym and doing exercises/exercising there?
3. Do you have a favourite fitness activity? If so, which one? (Or any favourite activities)... Which ones?
4. Why do you think fitness training has become such a popular sport activity?
5. Would you do exercises/exercise to get into (good) shape or because you want to be healthier?
7.Do you usually need to consult your doctor if you want to engage in (take up) fitness activities/training?
8. fitness training
Note: �fitness� on its own might be OK... But I think �fitness training� is better....
Just a few suggestions!
Note: I�ve edited these a bit; did a first quick response while at school!
