Replying to Knuckle front flip help.

Ok so let me start off with background. I can front flip flat off of one leg or both, and sideflip on flat ground. I want to try a knuckle Front flip but am not sure how to throw it. In a lot of edits I see a motion sort of like pulling one leg back and throwing it off of one leg. Amy tips are appreciated! When I try it I will post a follow up video. Also for the /claim my Instagram is @efrayne if you want to see proof of my flips on flat. Thanks and any tips help!
