I brace my core > suck in air into my stomach > hold my breath > lift > feel high blood pressure on my head because it takes about like 3 second to lift up the weight > breath out > carefully put down the weight (not slam, not eccentric)

Am I doing it right? I am a bit more concern about the "high blood pressure on my head"

Also, is there any cue to properly engage my core? I still cant feel the pressure on my core compared to bench.

Deads, is just hard to get everything right
