I used Gin's tape when starting out. I rank it as beginner level for anyone who aspires to master Cathe advanced tapes in a near future. It equates, for me, to the level of Cathe's Step Heat. I think it is a very well made video, Gin is motivating, it is well balanced program, but I never use it anymore because after conquering Step Works, Imax and the like, Gin's tape hardly makes any inroads on my heart rate any more. If you are already doing Cathe's Cardio & Weights and enjoying the level of intensity it provides, then Gin's tape will be a step backward for you.
