A deficit deadlift is standing on a plate or two to increase the ROM by lowering the bar's starting point.
Glute Ham raises are brutal, did you check the video? Yeah, it's just BW for me, although some beasts like Layne Norton actually hold weight and do it without pushing off at the bottom, hopefully someday I can do that.
They don't compare to any other exercise, they are very unique. But the action is a leg curl with isometric hip extension.
I stopped squatting because I needed a break from it, I ran Smolov twice this year (although I didn't finish the 2nd time) so I have squatted more times that most mortals this year even with a 6 week break. I hope to come back to the squat refreshed now.
My legs seem fine, definitely progressed in terms of the deadlift.
