I don't think is there anything like Asylum. The same I can say about Insanity. Speaking about the style of the workouts or if there an instructor like Shaw T. He's unique
But if we are speaking about Intensity there are few killer workouts out there, that I can compare and rise my HR as Insanity. Greg Cooks on CK (if you use heavy challenging weights), Shadow (if you follow the workout to the T), Amy Bento old advance workouts, and anything Michael Olajide. I'm getting Animal Conditional and it look really Hardcore
You may like it because is athletic bodyweight/calisthenics w/o choreography. But I'm don't have the program specifics details until I receive it next week.
ETA: I just though about The Pit Workout set. Is on my Amazon wishlist. I think that will be my next set purchase.
