For quite some time i've been meaning to include some very deliberate and slow negatives in my training. Something along the lines of the extreme advocated by DoggCrap. A problem I'm seeing, however, is that accentuated negatives to such a degree seem, while not quite counterproductive, a bit inhibitive for such lifts as the deadlift, where I'm envisioning an 8 second or so negative causing grip and similar supporting links to drop off the table long before the target muscles are sufficiently hit.
Has anyone employed such training while including such lifts? I'd be interested in hearing your experiences if so.
