Insanity?

Roskarin

I have recently been doing Insanity and enjoy it and have seen a change. I am almost done with the program next week and wanted to get some input from previous Insanity workout people about whether it is beneficial to start it again? I would like to do Insanity back to back but is it worth it or does you body just get use to the workouts and no progress or change happens? Please let me know your input or advice.
Thanks!!
