I have been doing deficit deads for quite a while now and they feel better than straight from the floor. Just wondering if you guys do deficits, how high up from the floor are you? For conventional deads the bar touches the top of my feet, and for RDLs or stiff leg I stand maybe 2 inches above the bar on a box. I just like the challenge of them really and I saw a video of Richard Hawthorne on instagram awhile back doing hella high deficits off a box.
Any higher than 2 inches of the ground and I feel my back rounding over just to reach down. Depends from person to person off of leverages and mobility, however.
