the PSLegs and the Leaner Legs withthe new 8-pak? I've ordered the 8-pak and can't wait until they get here!! I don't have any of the PS Series,but I'm strongly considering it. I have MIS, BodyMax, TWV,MSB, Step Heat, and Step-n-Motion1. With the 8-pak and what I already have, will I really need PS {any of them}? My goals are to build more upper body definition{especially in the chest and back areas}, get just a little more definition in my legs,and to lose 3% body fat. Thank You in advance Cathe!! I appericate it!!
