I have a very weak core and am suffering too often from lower back pain because of it. I've decided to really work on getting it stronger using Cathe videos since she has so many and is so good at working the core area! I'd like to start with her easiest ones first though. Can anyone rank the ab workouts she has from easiest to hardest? I have On Demand so I have access to all of them. For point of reference, I have found the Ab Hits to be doable. Planks are especially difficult for me, and forget anything other than just holding a plank. I'll need to build up to those. TIA!
