Said I'd bump this as I tried the Snatch Push Press for the first time this wednesday. It went up handy enough but lowering the bar felt excruciatingly painful, like my shoulders were being pulled out of their sockets. Even today my shoulders (right at the top, on the AC joint) feels quite sore.
I recorded two sets and noticed I was dipping forward a lot on the first set so looked to correct that somewhat on the second set. Seemed to improve.
Did these at 55Kg. Did regular push presses at 50Kg last week with no problems I felt.
Searched but couldn't find anything on this.
