the best indoor excerise??

Jumping rope. Do several 3 minute rounds, add a few sets of pushups and situps, and you have a good, well-rounded workout.

I'm afraid my answer would get me in trouble. FYI, it's also my favorite outdoor exercise too.
Go play DDR!!! No, it's fun but, I don't know if you want to play a game like that. Umm, just go get a treadmill or do some regular exercising if that'll help.
Bedroom aerobics, handstands and push ups.
