I have not done the Insanity Asylum, but I did the entire Insanity rotation. The good news is that I increased my cardio during the cycle, which made it easier to do the Cathe workouts that I used to struggle with. The bad news is that even with all of that work and a very clean diet, I did not really lose any weight, which seemed impossible, but it was true. I also did not enjoy the workouts. Not just because they were tough, but because they were so boring and repetitive. No matter how hard Cathe's workouts are, I still look forward to doing them and there is very little dread factor...and some of them are 3x as long as Insanity, which means I'm burning even more calories, and I'm actually having a relatively good time doing it. I was excited about starting Insanity, but in the end, I did not enjoy it and I could not wait for it to be over so that I could go back to my Cathe workouts. I started LIS in November and I've managed to actually lean out a little more. Insanity did not give me those results.
