ME Concentric goodmornings with coach Stump

I've been wanting to do max effort concentric goodmornings for a while, but haven't done them because I would have had to do them off the pins of the power rack  with a normal squat bar ( and my hands could get in the way ).  Stump had straps which solved this issue so I finally got to do them.  The workout went as follows ( I could be remembering some of the specifics wrong ) :

A few sets with just the bar

135 x 5

135 x 7

185 x 4

185 x 5

225 x 3

225 x 3

255 x 0 ( I know I can do this, but still have to just get used to the movement )

255 x 2

255 x 2

I can see these helping my deadlift HUGE.  As with my deads, I can see being able to do quite a bit more weight with this after I get used to the motion.

On to some squats, working on the hip flexibility and getting to parallel

Maybe 5 sets of 135 x 5 to 7.  

Stump verified that I can get to parallel.  I know the weight's light, but this is HUGE!   

We figured out that if we set the pins on the 11th hole up, when Im at parallel the bar just touches the pins.  This is really going to help my squat workouts when I'm solo since it's hard for me to know when I'm actually parallel. 

135 x 5-6  to bar touching the pins

135 x 5-6 to bar touching the pins

Ah, lets set the pin to the 10th hole then only my hands need to touch because I was finding that I had to try to move my hands out of the way before.

135 x 5 (to hands touching the pins, ie they're all essentially to parallel)

185 x 4 

185 x 4

225 x 3

225 x 3

I feel like I'm really making progress on the squats, woohoo I can get to parallel!   Reaching my short term squat goal is in sight  ( ie being able to squat 315 to parallel with good form ).

I then did a few sets of back hyperextensions.  A few with no weight and a few holding on to a 25 pound plate.
