I am thinking of purchasing the Insanity Workout DVDs. I have tried them before and think they are great, but I'm just concerned about what happens when the 60 day program is done... Do you just start the program all over or are you done after the 60 days?? If anyone has used this program, can you please let me know what you think of it and what you do when the program is done to continue losing weight or maintain the results?? Thanks!!
