Oh, another low back exercise is the good morning performed while sitting on a bench since this disables the hams to a greater degree.
Be sure to start very light since the greatest stress to the erectors will be in the bent forward position.
OK first the ATP. You're correct that CP will take over after just a few seconds but after you rest the glycogen stores (which are bigger from eating more) will restore ATP. It's not making you STRONGER as such but increasing your work capacity a whole bunch. Hope this answers that. If not I can find some other sources but here is a start:
LIFT-RUN-BANG: Developing your raw bench - Part 1
I agree with you on the sticking point issue. Although I wouldn't call it "muscular weakness", I think this encourages "weak point training". Really it's just developing the muscular base that is needed for developing the lift. Targetting the weak part of the ROM did not work for me AT ALL, until I started thinking that the first part of the lift was the "weak point" and started pausing my benches, pausing my squats and doing my deadlifts from a mechanical disadvantage. I think anything that increases the ROM of the lift (close grip benching, deficit deadlifts, deep squats etc) will benefit the raw lift. Partials however I do not. Unless it's from a mechanical disadvantage and you're actually lifting LESS (example deadlifts from mid shin). Just how I feel
I'm no Oni but I think it's Creatine Phosphate.
Also, to add into the Assistance Programming debate. My 2c is that the more you rely on assistance in your programming the less margin for error you have in your programming compared to if your program is focused on frequency/volume of the lifts you're trying to improve
Have you heard of g rows goosey?
From what I have read round back goodmornings used to be popular for what you describe but not really popular now because of the fears of any round back lifts these days.

The MedX or kieser low back and exercise lumbar pieces will do both of these. Now, I know many on this board have never tried either of these, but these are the real deal.
I found the MedX low back machine on Youtube, really impressive design!
Kieser training I remember for ACA a while back. Really smart and methodical on their treatments which I can appreciate. Would've loved that sort of approach when I tore my MCL (grade 2), yet the Docs at the hospital diagnosed as a sprain lol.
The only thing I work about is people getting the wrong idea about flexion based lower back movements. People who know what "a little" is like people on this forum are okay, but let laypeople hear that and disc are going to be flying out of peoples backs and bouncing around the gyms haha.
With the seated Good Mornings, try having your legs straight out in front of you to miminise any other muscle involvement =)
The legs should be bent on this exercise and not straight or contracted.
5)A movement I kind of "came up with" one day which really smoked my low back is the following: use a straight bar, feet shoulder width with a "soft" knee (maintain this knee position throughout), and peform a Romanian Deadlift (keep the head up, and shove the butt back and keep a neutral spine).
Keep the bar close to the body, and go down until the bar is at mid-shin (remember, keep the neutral spine).
Once you've reached mid shin with a neutral spine, round out the back slowly until the plates touch the floor.
Now, using only the lumbar muscles, extend back up, slowly and smoothly, into the neutral spine position.
Do not come all the way erect (like when you began the set).
Once you reach neutral spine, round out again and repeat the extension. 15-20 reps. You won't need much more than the bar to start this, and your low back will be screaming after 15 reps. It is kind of an RDL, SLD, Good Morning, and back extension all rolled into one. Try it.

Because straight legs will stretch the hamstrings. You're not trying to build the hamstrings on this exercise, you're building the lower back through flexion and extension
"Truth is, I tell seminar attendees all the time that a training program rarely fails due to improper assistance exercise selection. It will fail from poor programming, a lack of consistency, and failing to accommodate the ups and downs of life. In other words, a program must allow you to adjust a bit when you have a particularly good or absolutely shitty day. It’s not as simple as “Do this.” You have to rely on that thing that rests between your ears." - Wendler
