Frit, great stuff.
Your response is precisely what I would have predicted.
As I stated in another post, I have started to perform pulls from the hang and cleans from the hang.
I am doing this as I recover from a sprained interspinous ligament around L5 downward over the sacrum.
This allows me to continue to get hip extension work in, albeit not as heavily loaded as DL’s, while concurrently providing a fairly high CNS stimulus. Most importantly, I am able to perform them without aggrivated my low back.
I am experiencing exactly what you have listed as the contributing factors towards developing your clean.
I, however, am coming from the opposite direction, as my assistance lifts (relative to the clean) are already strong (e.g., DL variations, GM’s, GHR’s, etc.). For me, as you would guess, the matter is perfecting the skill and, as you eluded to, developing my wrist flexibility.
The degree of muscle cross-section in my forearms (brachioradialis) is fairly significant. Hence, I am only able to flex my elbows so far. Accordingly, my wrists must compensate for my lack of elbow flexion by over extending in order to properly catch/rack the bar.
I don’t plan on converting to an Olifter, however, I am really enjoying the cleans and pulls.
My first benchmark is a 315 hang clean or 140kg if I end up getting some bumber plates.
After having worked on the technique for about a month now, I performed 8 easy singles with 205 catching the bar almost standing straight up. I am still a little reluctant to squat down to catch the bar, as this would involve more spinal flexion.
I actually think that I could hang clean 315 right now, however, I do not want to risk re-aggrivating my low back by catching the bar in a half squat position.
