Couple technique points:
* You never get your back set. It’s still quite rounded. See how arched Chad’s back is at the start in the video Murph posted?
* You’re jumping when you get the bar just above the knees, but you shouldn’t be until you’re in the pockets position.
* You need to sweep the bar back into you throughout the lift so that you make contact with the hips at extension - see Chad’s video from about 0:27 to 0:33
So what to do to work on these?
First, just make sure you get your back (both upper and lower) set before you pull anything from the floor. Show your workout buddies The Chad Vaughn video and get them to cue you if your back isn’t set. For me, I often think I’m tight, then I see the video and realize I’m not.
I think doing some work from the high hang or blocks would help you find the power position better and also help with the sweep in.
Snatch deadlifts can help with this as well.
Probably stop doing power snatches until you are comfortable with a full snatch.
I also like snatch drops and snatch balances to help with confidence under the bar. Just remember to check your ego at the door and only snatch balance up to where the bar is barely being elevated. It’s not a snatch grip push press followed by an overhead squat, it should be a little bump to unweight the bar, then an aggressive push under the bar.
I’m sure the other guys will have even better suggestions.
