I always like to gravitate towards simple and sinister. I did weeks and months of zercher lifting and handstandpushups (freestanding and/or between chairs). I am almost two years into heavy A+A one arm snatches. It is a liftthat has it all to me. Essentially I lift a weight up from the ground and bring it overhead. A few standing ab wheel rollouts afterwards and for arguments sake I could reason to counterpart the posterior back work with anterior ab work. I don't believe in wanting to address everything. Doing essentials and I do many things right.
