Im going to be going for abdominal surgery in the near future (no date yet but certainly within 6 months & possibly much sooner) and was thinking that it would be a good idea to work on strengthening my abdominal muscles before hand.
I do have pretty strong muscles but I figure that improving what I have can only help & hopefully mean faster recovery & less recoup time.

Any suggestions for things I can do to help with this? I do a lot of med-heavy lifting as part of my daily work and 1-2 times a week I do the essential movements workout (pushup/pullup/plank/squats)
