Try to sit in the hole as long as you can. Sets of five are preferable. Side bends - Use bodyweight as soon as you can to toughen the obliques. Good Mornings - Use about 100kg for sets of eight. Pull as hard and as high as possible without dipping below the bar.
Triples are best.
Do these from the front. Snatch from hang - Develops the second pull. Sets of five will develop the grip as well. Now, back to my milk.
