1. I can do 20 push-ups.
2. I can push-up 20 times.
[Are both okay? Can we use #2? Do you have similar expressions to #1?]

The first one is the only one that I've heard used.

Thank you for your help.

3. I can pushup 20 times.

#1 is a correct sentence.
Can we use 'pushup' as a verb?
The score/point for #1 is four. Then what could be the partial point for Sentence 3?

Push-up is a noun, not a verb.
