I got money for my birthday and am not sure how to spend it. Right now I have the Body Blast Series, B&G, Drill Max and I pre ordered STS Cardio. I am torn over purchasing STS or for about the same amount of money I can get the Hardcore Series AND Intensity Series. I can't make up my mind as to which would be the better purchase. My gut feeling is I will have more options getting Hardcore and Intensity but everyone seems to really love STS plus I pre ordered STS cardio.....I am 7 months pregnant with twins right now so in a few months I am going to want to shed the weight and get back into shape ASAP. Any advice would be greatly appreciated!!!
