Hi, I currently own the Maximum Intensity Strength video, and I do it 3 days/week. Is this video my best bet for losing fat and building muscle or is there another Cathe video better suited for my purpose? I was wondering about the slow and heavy series and whether it would be better in conjunction with my cardio which I do 6-7 days/week (am attempting to lose MAJOR pounds!) Any advice is appreciated, I've been working with weights only about 4 months, regularly using 8, 10 and 15lb weights with the MIS video. So, move on to another Cathe or stay put? And if I do move on, please suggest to what and how often. Thank you so much for any answers. Donna
