As far as “posterior chain” size, I can’t say I’ve given a proper deadlift the chance. I switched to mat pulls before I started training a hip hinge movement for size.
The changes I did make, to focus on increased tension and TUT:
- added chains
- focus on the hamstring stretch at the bottom, and glute contraction at the top
- touch-n-go style, with very controlled eccentrics
I’m not using chains in the Westside/speed sense. For myself, I realized that once I get the bar off the floor, the rest of the movement is pretty easy. With the chains, it makes the whole movement “hard”, and forces me to work the whole time. There’s a lot more tension on my back this way. (Other people have more trouble with the lockout, in which case something like reverse bands might make sense.) My goal was to keep the applied force fairly constant through the whole movement.
After getting a bit of SI joint irritation, I looked for deadlift information on people with similar builds as my own. After watching a few of Richard Hawthorne’s videos, I adjusted my form to be more like his, starting with a strong “upper” hamstring stretch, and focusing on wedging my hips forward during the lift. Every rep gets a strong hamstring stretch, and a strong glute contraction.
The touch-n-go style, with all of the above, increases the total TUT. Every eccentric is controlled so that it’s reversible at any point. The plates touch, but they’re not bounced, and there’s no deload of the weights.
Growth has mostly been hamstrings, spinal erectors, and traps (mid, uppper, and lower), with some in my quads, glutes and lats. However, my glutes respond better to deep back squats, and lats respond better to weighted chins.
I haven’t done it, but I imagine those same ideas would transfer fairly well to a deadlift from the floor.
