Recently days, I find myself able to use leg drive on my bench which I see many power-lifter does by thinking I'm pushing my body down towards the bench rather than pushing the bar up towards the ceiling, is this the correct technique to do use leg drive? I am able to feel the force from my feet towards the bar, and tighten the core is really an important factor to transfer the force. I've never been able to do that with cues that shown by Alan Thrall nor Candito

Maybe i missed this part. Still not able to feel my lats yet so bending the bar doesn't really work now. Might cause my lats is still weak, not built. Might sounds illogical but those cue feel, doesn't comes in 1 day, it just come slowly.

There's something called the Bulgarian Method covered by Omarisuf, it's mostly squatting everyday. I don't think this is the same as the original Bulgarian system though.
