I had a very similar problem as you when learning the lifts. My coach gave me a lesson in humility and I actually did a little video on youtube demonstrating what he did to me. I'm not a little fellow and I carry a lot of pillows, as my father calls them, in my extremities. But it doesn't keep me from getting into the rack and my palms onto the bar when I jerk.
Here's the link. I hope it helps.
for some reason, I can't get your vid to play. I'll check back later with hope that I can help.
All the best,
