Insanity was a lot of fun but not my favorite cause it is always fast paced so you get your endurance up big time but I just don't like always being on the move. It's opinion on that matter so you may like it better if you are a fast paced type of person. I did both of these workouts in the summer during the day as well as my own workout at night and it gave me great results.
I was taking creatine and whey protein for recovery purposes as you most likely will need it until you get used to the tempo of each program as well as keeping up with the people on it.
