Not to get into too much detail, when she goes 90% or above she panics and gets nervous, then mentally breaks down as she brings the weight closer to chest. I tell her to relax, trust her spotters (me) and the shirt. She ALWAYS cocks her wrist back and her forearms are not lined up with her elbows. She is fighting the groove of the shirt trying to accommodate her raw groove which is a big no-no. I have a general idea on what she needs to do and what cues to shout, but how does one convince a lifter to break that mental barrier? I'm getting frustrated myself as I been training her for months now but I know bringing negativity to the table won't do any good.
