Anyone Planked While Hanging SO?

Pardon me if I don’t have the acronyms correct, but I believe I’m hanging straight out by laying between a chair and my bed. While in this pose one can plank for the duration of the stretch. Anyone tried this? I admired someone’s signature on here, it read something closely to this: big cock, strong abs, big muscles, strong mind

plank?if you are horizontal, parallel to the floor, then the weight hangs between your legs, between your ass cheeks. Not straight out. Straight out is same direction as an erection.
