Thanks, i do try to do those sorts of exercises, they just play havoc with my back. the core muscles ( under the wobble.lol) are all strong and firm, but think there is still some fat too lose over the tum. Although according to the height weight chart i am near the low end of weight, i think i need to go under to lose the last actual fat and then put back on muscle tone to build back to normal weight, but not with fat!
