Came across the 'reverse plank' in abs level 17, wasn't sure what it means, and theres no instructional video on the website for it. Does anyone know?

If there's not an instructional video on this website, YouTube is a good option, I have got a few from there.

For future anyway looks like Gligor already sent you a picture of how it's done.
