Attacking one's absolute max as mandatory every session will not work in our drug-free environment. Working at that near-level and sometimes that very level or exceeding it when warranted is what you are looking for. A lot of different forces come into play... especially the individual and chemistry between athletes and between athlete and coach. Knowing when to let your lifter "have his nose" so to speak and knowing when to rein him/her in becomes vital. Likewise, pushing one when one needs to be pushed is also part of the menu.
