Hi, I still consider myself new to Cathe's workouts and am still trying to figure out what will work for me to get this extra 10 pounds off. I am eating clean, exercising well and can't seem to budge. I saw one person comment on one of the tapes being "endurance" versus "strength building". What am I trying to do if I want to burn calories in the most effective way. I have not been big on strength building and am trying to incorporate this into my rotations - I know it will help burn calories. I need to lose this fat on my body and gaining strength would also be good. I am up to 10 pound reps on many upper body - and have seen gains (starting at 5 pounds) in chest, biceps, shoulders. The tapes I have are: rythmic step , the wedding tape, circuit max and I am in the process of buying some new ones - including some strength tapes - BUT, I want to buy the right ones. So...my question is for a beginner to weight training, I assume it is better to build strength first, correct? Can all of Cathe's tapes do this and/or which ones will do this best. Also, should one continue using the same tape until they stop seeing results? Thanks so much. I learn so much from y'all. Sandy
