OK, hands are on the bar, weight is on the heels. I'm "squatting down" loading the hamstrings and trying to get behind the bar.
I'm going to explode at the right moment, once I get into the right position.
Do I know when this moment is? Do I "time" it? Or do I keep tight, trying to get into better and better position until the lift just happens?
Like when you fire a gun. You don't Pluck the trigger, you slowly squeeze until... Bang! One of our shooting fundamentals back in the day was "Be Surprised."
Are you "surprised" by the bar breaking off the ground? I've been doing tons of Sumo/Squat stance DLs in the power rack. My feet push Out, chest kinda up, almost falling back. Then all the sudden, Deadlift.
Am I on the right track, or just all to hell?
