I am curious what a good ab routine would be? I have lowered all my volume and training down to around 4-8 total sets for each bodypart.. I am thinking seated leg tucks 2 sets, and cable crunches 2 sets.. but theres no direct oblique isolation work...
I do the same as b fold.I train the abs just about every training day(every other day).I too am only concerned with function, not looks(I'm pretty skinny anyway).I just do a couple of sets of hanging leg raises with a plate tied to my ankles either at the beginning or end of my weight workouts.I've heard these can help decompress the spine somewhat so they are particularly useful after squats or pulls.
weighted knee ups (2-3 sets of 15) or weight straight leg ups (for hip flexors 2-3 sets of 15)
weighted cable crunches (3 sets of 15)
weigt cable twists (2 sets of 15)
I have been doing this for 2 years now and i am very happy with my results
