Maybe you should strap that electric exerciser thing to your head for a little home shock therapy...

Pick up a hobby that exercises those muscles, I have chosen the drums...other suggestions:

1. A little less Chi-nookie, a little more actual nookie.

2. Get sent to jail. This can affect your a** in a myriad of ways, but I figure just running away from the sweeter inmates would be enough to do the trick. Of course, if you aren't fast enough you'd be in for some exercise of a whole different kind.
