Changing workout routine?

Hey everyone-

So for some reason my body seems to get very quickly acclimated to whatever workout I decide to do.
I am currently doing 5 days of Ripped in 30, and 5 days of INSANITY. Some people might argue that its "too much" but honestly Im fine with it.

Only one issue though. In the last 10 days I have felt, and seen pretty much no results. These are both very good workouts, and Im also using a Bodymedia Fit armband, so Im a little confused on why nothing is happening. My caloric deficit is between 600-900.

People have suggested I try and change things up. Not really sure what I should do. Any ideas?
