關於Pushup的意思和用法的提問

A: They mean the same thing. Using “goes” is very casual and some consider it improper grammar.

A: ‎I can do 40 push-ups. I'm trying to push my limits.

A: I think he can do 5 pushups if any....
(I think --is too positve, you are saying it as if there is a slight chance he might be able to do more. Though your sentence says you don't think he can even do that amount (if any). The sentence in this case needs to stay negative throughout because you are not sure what the person is capable of.
Because the point of this sentence is you are hopeful that you are not underestimating his abilities but you hope you are right, that he cannot do more than 5.
I don't even think ---this starts off neg and ends negative.
At best I think ----this starts off neg and ends negative.
I don't think ----this starts off neg and ends negative.

A: It sounds great Just remember pushup is in plural form so its "pushups". Keep up the great work. 😜👌

A: If you use a verb as the subject of a sentence it should be in the gerund. Otherwise it sounds overly poetic.
