Thanks for the initial feedback on my lifting! i've been working on the pull from the ground as you guys suggested and it seems to be getting my positioning a bit better. I've done quite a bit of work off boxes (http://www.catalystathletics.com/art...p?articleID=52
Great Instructions!) and more pulls from the ground.
I caught an 85kg snatch on film yesterday (a PR for me!) and it looks like i could get a bit more extension by pulling from the knees into a bit more of a vertical position before the main drive? Either that or get stronger i guess?
