Do pushing up...?

[crazYgeeK]

Could you please point out the incorrect ones in the following sentences:
1. I can do pushing up for 30 ones.
2. I can do pushing up for 30 times.
3. I can do 30 push-ups.
Could you please give me the more natural sentences to express such an idea?
Thank you very much!

What's your opinion, crazYgeeK?

One of the three sentences is very simple and natural.

Thank you! I think the #3 is the most natural of three ones but if so, that is the case we use the noun "push-up" to make sentence, I would like to know the natural one in which we use the verb form, could you please show your sentences?
Thank you very much!

There is no verb form. We do push-ups.

"To push up" is a [phrasal] verb but it has nothing to do with the exercise you're referring to.

For info, in BrE, you're just as likely to hear "press-ups" as well - "push-ups" is AmE but has probably crossed the Atlantic like many other things.

Congratulations if you can do 30. I can barely do 3!

Dear crazYgeeK,

A "push-up", in the context of the third sentence you proposed, is an exercise in which a person lies facing the floor and, keeping their back straight, raises their body by pressing down on their hands.
It's not a verb. "Do" is the verb.

OK, drop and gimmie 30.
