"Ugly Abs Training" Between Ab Blitz Cycles?

Hi Coach, do you still consider exercises like Overhead Supports and Zercher Holds to be effective in strengthening and developing the abs in between periods of ab blitz cycles? If so, how many days a week could you use these exercises?

The human body has not changed in 2-3 years. Why would they become ineffective all of a sudden?


Fair enough. In general, where would Zercher Holds and Overhead Supports be ideally utilized within a training routine?
