Well I brought in my Sissel SitFit type device, its basicly like a small squashed swiss ball. I put this on the edge of the high bench at the gym, it sits over the lip, and off course my stomach sits ontop. Really improves the exercise!
Firsly it wobbles a bit, an interesting feeling, and secondly it allows your body to curve over, molding into the shape of your body. This allows the spine to flex. You can literally feel your erector stretching and spine open up at the bottom of each rep! Because the spine flexes the erectors are worked dynamicly.
