How do you do a proper sit-up?

I think you want to say “proper exercise routine.”  Is this because you want to exercise to lose weight, or are you just interested in health?

That's not what I said. I said I want to know how to proper execute a sit-up.

You don't need to write "proper" every time you use it. In this case I'd interpret the sentence as “How do I do a good sit-up?”
assistant
I meant to say "properly". It's important to emphasize that because there's a correct way to do it.
