Ive begun to notice that i perform lifts the best when i just walk up to / or just jump under the bar and get'r done before i can think too much about it.
Take a clean or power clean for example...I'll see those dudes that sit there for half a minute stooped/squatted over the bar mulling over in thier head the execution of the lift before they do it.
I for some reason seem to lose like half my damn thunder doing that crap and will very regularly screw up a lift. Im much more successful when i just walk up to that thing and yank it off the ground.
Or with squats, people will have this big looonnnng setup where they are grabbing the bar, planning and plotting, walk the bar out, take 3 big deeeeep breaths and then squat.
I ever do it that way i just get crumpled, doing heavy singles i gotta angry power leap underneath the bar and just get it done as fast as possible. I seem to lift more weight this way.
Not sure if its overthinking, losing tension or probably a combo of both. Kind of a funny brain game you need to play sometimes.
