All PBs, even for a single. Never had that much weight over my head before. Ever.

Push-jerk
1 x 57.5kg - failure to launch. Complete lack of technique.
5 x 50kg - struggling
5 x 50kg - better
5 x 50kg - got it!
5 x 50kg - got it!
4 x 50kg + 2 failed attempts - too confident, should have waited longer after the last set.
Tweaked my back slightly somewhere in there too, probably early on. Not staying tight enough.
I don't think I've ever done push jerks before?
The difference was in catching what for me is a heavy weight over head, with emphasis on the catch. The weight goes up easily, it's getting everything lined up to catch it that tripped me up.

I didn't video it. I was going to, put a white shirt on and everything!
As per LauraR's suggestion, I will work on push jerks with a reasonable load to get more comfortable with the movement. I was really shocked at how badly I did with the push jerks, I was hoping for 60kg, which would have been a HUGE breakthrough!
