No, I only bent with my abs, similar to swim butterfly when I push.

If I make a v, I lift my legs then my mass center moves too. I do a rotation.

Zero relevance to what you wanted to know. Just use basic exercise descriptions or, if it's very different, post a video.

I find a solution. I use a tailoring tape instead of my iphone. In two weeks, I get .5 cm. The iphone can do an auto zooming. This is a perspective effect, the problem. Now, I must learn to close my mouth on final repetition in order to not disturb people.
