Kk thanks guys, i am aware of the value of deadlifts from a deficit and use them often to train my bottom end.
The halting deadlifts and rack pulls still seem intriguing to me though. I read about them in this article by Mark Rippetoe, and he seems to know his stuff.
I think the reason rack pulls dont significantly increase peoples dl’s, is because for a lot of people, their weak point is the floor or around mid shin. Pulling from a deficit and halting deadlifts seem to be a good method of improving this part of the ROM.
Also, by shortening the ROM (halting deadlifts) your able to handle more weight.
Usually someones top half is much stronger, and thus rack pulls with heavier weight would be beneficial in this case.
EX:
If you can only do the bottom of the movement with 300, but can do the top half with 400, then if your doing full dl’s then your really only using enough weight for the bottom half to benefit.
Sure in the long run, the bottom would become stronger, and you would be doing similar values in both areas. (maybe 400 through the entire ROM)
But if you do halting deadlifts (bottom) and rack pulls (top), your able to increase the strength in both areas, not just at the weaker part.
in the long run you may be (400 bottom and 450 top)
Also, theres probably a lot of carryover from using heavier rack pulls, like stabalizing muscles and grip, etc. that would actually help in the bottom of the movement.
(so it might end up being 425 bottom, and 450 top)
Im not too sure if this is the actual case or not though, but im just throwing out the idea. The author of that article seems pretty credible, and it seems like a feasable technique.
***Also think of this. If you had someone only do full olympic cleans, versus breaking down the movement into deadlifts and hang cleans, which method would produce better results? Im not really sure, but its something to think about.
