Yes, i did work backwards with my X-Step. I wanted a very compact footwork because I was going for Power+Accuracy. With Accuracy being the greatest when it comes to the footwork I realized. It harnesses your body placement. But I do other things in opposed to getting accuracy.
1) All I did for about 2 weeks straight was standing in a stationary position and start my pull from my right pectoral, getting the feel for acceleration. Then, after the 2 weeks I slowly worked my X-Step by taking tiny steps. while still starting my pull from my right pectoral, and pulling through at full speed.
First, I would start with one step and pulling through, then I would work two steps. Then I worked a really slow X-Step. By this I mean stepping through the X-Step rather then running through. I worked my X-step and pull through this way. The whole Time I was doing this, I was always starting my reach back from my right pectoral and pulling through at max speed. Because your right pectoral is where the acceleration starts, while most people release at that point, which I was doing before this. After about a month I worked my X-Step all the way at the speed I wanted to incorporate into my game with 2 leading steps.
2) By kicking your back leg up clears your hip and gets weight forward, I'll just say it right there.
3)The reach back you seen in the videos, is the reach back I use all the time, I just recently incorporated that in my form like a week ago because I wanted to get more out of my throws, not just distance but a better follow through and it's also helped me lead with my elbows and not come to early with my body. I figured that out for myself.
The hardest thing to grasp was learning to clear my hip. I just did not understand it at all. I would kick my back foot up, but still not clearing my hip or I would clear my hip but I would lung forward and not pivot. So I made clear of this and worked extra hard for a long time before I finally got it. The easiest thing to understand was the Acceleration for me, I still asked a lot of questions, but those were the answers I already knew but just wanted to make sure I was right.
My favorite part of DG, are the throw ins. We play a rec round you can expect me to hit at least 1-2 125' throw ins. I practice those all the time.
