Hi everyone! I have been hearing about Cathe for months now, and everything I've heard has been wonderful. I have been using Joyce Vedral's weight training programs for about a year and have recently started doing BFL (the eating plan and upper body workout, at least, no supplements). At any rate, I've found that since I work out at home variety within the BFL program is going to be limited and I need to be challenged! I specifically want to build up my upper body and whittle down my big behind and thighs. I'm an advanced exerciser and have quite a bit of equipment at home (bench, barbells, plates, dumbbells). I don't have a step but I'm hoping I can improvise with a chair or my bench. I'm considering purchasing the PS series and possibly MIS. What do you all think? Any suggestions would be greatly appreciated. Thank you!
