Taking both of your words of advice, I did a snatch workout today focusing on super slow pulls. Worked up to a 176 snatch (a previous PR for me) very easily and decided to go for the 186, which has been a goal for some time. The pull on this is much faster than my previous lifts of the night, but it felt good going up. I think I'm able to get under the bar a little more balanced due to not toeing so much.
This video is the 186 lb attempt, featuring a clumsy escape from the failed lockout. Got it up no problem but the overhead position, whether due to weakness or confidence (I was picturing Matthias Steiner prior to the go, probably not a good idea in hindsight), didn't lock and my foot went wonky.
As far as strengthening the overhead position, specifically the moment of lockout, is there anything other than snatch balances or drop snatches that I should be specifically focusing on in technique training? As far as confidence in the lockout goes (I feel like the above lift was mine and I sissied out), I guess just working with close to but still sub maximal (like 85-90% heavy singles) is a good idea?
