I've become a total Google junkie of late. Feeling the need to add to my gym training regimen, I came across Power Zen, part of a Reebok site devoted to core training. Before deciding whether the core trainer equipment sold at the site was necessary, I decided to simply try the exercises. What I like is that there's no writeup at all, but an animation that plays over and over so you can follow along and try to duplicate the movements with just your laptop watching. I may never get to the point of purchasing the 'core board' but the exercises all by themselves are great. I'm not giving up Google cooking. I'm just adding Google workouts to counter the effects.
