this guy rocks. btw, i think a pendlay row involves a complete deload at the bottom of the movement. in other words, the bar is rested completely on the ground before you start bringing it up to your body. what you're doing is a regular barbell row...which is fine. keep that up. i agree that your form (based on the videos you posted back in february) is good, but your movement seemed a little fast on the rows.
GHR = glute ham raise. triex = tricep extensions of some sort. you've probably figured this stuff out by now. good luck.
