Of course Adam didnt invent the penultimate step, Adam made a video of him explaining it step by step, his way, (which by the way is not the same amongst different track and field jump coaches), and using hand claps as a cadence guide. This dude comes along a short while later, AND MAKES THE EXACT SAME FUCKING VIDEO, USING THE EXACT SAME HAND CLAPS. Adam has a very extensive background in track and field, Jacob has a vertical jump program, Adam was explaining the penultimate step the way it was taught to him, by his coaches, which as I said before is not the same as other coaches often have different methods of teaching it, and it got copied, fed back out by Jacob as if it were his info. I mean if youre going to use someone elses info, just fucking give credit in the video. He of course wouldnt do that as it would divert attention away from his program.
