I love how some of use on this forum have been doing shit for years and posted on them exhaustively but nobody takes it seriously until Dan John or Mike Robertson 'suddenly' discover it years later. It's so gratifying.
This is why so many people just don't bother any longer. Swings are like three years ago. Great but not exactly news.

You learned these before I thought. They are not that complicated. I know it was over two years ago. Me and Dan have both posted extensively on these.
I'm not sure what attack the zipper means but if it's what I think it is they it's going to promote flexion at the upper back. Also, why should you need to "shove" a heavy weight behind you when the swing back is "pulling" it behind you and all you need to do is accept the pull while controlling the hips and back? That's over-coaching in my book.
You've got not time to speak of to reverse the kettlebell or dumbbell. Any concious thought your are trying to give to silly shit like "shoving it" is only going to hang you up. While you should be doing it, quite naturally, you're thinking about artificial things like 'shoving it' and all that does is 1. help you not, young padawan and 2.) interrupt the flow of the movement.
On snatches why should anuj take a bunch of time to practice a technical movement for the purposes of conditioning. WAY too much effort to expend for a secondary goal.
There is nothing he could get out of snatches conditioning wise that he couldn't get out of simpler derivatives. You just be diverting resources with complications.
That is, I have nothing against snatches but for the purposes of conditioning it's like learning to break dance so you can get in shape.
