Just to clarify, Coach Jen's suggestion of resting 1 day between core workout sessions means 48 hours.
Strength training works by creating microscopic tears in the muscle fibers, which then grow back stronger. But it takes time for this to happen, which is why it is important to rest between sessions.
There is little advantage to doing a core workout video twice over in a single session. Having worked the core muscles once, you will have got most of the benefit anyway - doing it a second time offers minimal additional benefit. You are better off spending the time doing a different workout entirely.
I agree with the suggestion however that visible abs is mainly about low overall body fat, not about how hard you work the core. And the best way to achieve low body fat (and visible abs) is through an overall program of cardio, all-body strength training and watching your intake, rather than heaps of core videos.
The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man.
