Yeah, you're right. My brain is telling my body to do what Starting Strength says. But something keeps getting lost between command and execution.
I'll keep at it, though. Since I read the book, focused on progressive loading, and focused on multi-joint barbell movements, I've felt a lot better. Now, if I can just get my form right, who knows? Maybe I'll accomplish something. I wish I'd read Starting Strength when I started lifting. Pretty much everything I was doing before I read the book was wrong.
Ok. I re-read the chapter on the deadlift, watched the 5-step video, put plywood on the floor, practiced arching my lumbar spine, dropped the weight, narrowed the stance, and tried again:
I still think that, as the book tells me to expect, step 4 is the hardest to master. To get the back close to the illustration on page 107, I feel that I have to drop the hips a bit -- which you're not supposed to do. So, I still don't feel that step 4 is what it should be. As always, your thoughts are appreciated.
You set your low back a little less with each rep. While it at least isn't moving while you pull (which is good), it would be better if it was flatter to begin with. It will help.some mechanically if you get the weights to the same height as your feet. Put some plywood or house stall mat under the plates to lift them to the same height as your platform.
Push your stomach toward the ground before each pull.
You're right: I noticed that the plates being slightly lower than the plywood was not helpful. I'll follow your advice. Much appreciated.
Been doing SSOC as well. It is well worth it, even if you can only do it for a little while.
