I was wondering..as I am trying to increase size and definition of my abs what kind of training approach is better..training them once or twice a week or almost every day?
Right now I train them like 25 minutes a day, but most times I struggle to reach failure with lots of exercises and struggle to focus on the lower abs. The only one that seams to work ok is hanging legs or knee raises .and few times i get tired not by core engagement but by the fact that my upper body needs a rest. Especially my lower abs are very lazy even with leg raises.
Would it be better trying to train them for 45 min twice a week instead?
To be said is that I struggle to gain mass , in general, due to 2 bowel operations and bowel diseases that do not let me have a big food intake and don't let me absorb nutrients properly.
That's what made me think that maybe I am overtraining them .
