I did 20 push-ups this morning.

I do push-ups every morning.

Grown ups should set a good example for children.

I wanted to give you a heads-up about the meeting tomorrow.

The mark-ups on the products were too high.

There were several toss-ups during the game.

I enjoy watching stand-ups at the comedy club.

I collected several power-ups during the game.

I have many one ups in this game.

He always one ups his competitors.
