@purchell53 I'm not sure but I think you'll not be able to use the posas in that way, if you use the psoas you can not use only the upper part of the psoas, you'll always use the full Iliopsoas muscle the through its full orgin (t12-l5) an not only t12 (m. psoas maj and m. iliacus) the psoas also do lateral flexion (moving your trunk to the side) but no flexion in the lumbar spine afaik.
It does! i just never thought of it that way. Question: could it also support FLEXION of the lumbar spine, given that it has connections on t12.... pull t12 towards the GT of the femur and we get flexion, right?
@Krpi No I hit all of my reps, but I do what is recommended in the video not to (getting tight AFTER grabbing the bar in the bottom position). If you go to my channel it should be my most recent video called "HFS and Deficit Deadlift 11-26-11".
@EliteKrieGer -.- "chance" I obviously mean "change" and i forgot to say: through the "extension-action" of the psoas you're unable to archive full extension in the hip and compensate through lumbar hyperextension (like Kstarr said)
pretty easy, just search for the anatomy of the M. psoas major an you'll find the structures it comes from (Origin) (T-spine 12 +lumbar spine 1-5) an the structure it pulls on (Insertion) (lesser trochanter of the femur) chance puntucm fixum and puntum mobile et voila the psoas does extension in the lubar spine instead of flexion in the hips :) i hope this helps, greetings from a german PT ;)

Ok, I just wondered if you thought you had missed reps due to psoas activity since you seemed to think this was an important tip to you.
