Rainy day exercises

AmbsBams

Since it has been threatening to rain ALL day (still hasn't started) I have come up with a way to get a little exercise in while entertaing my 9 month old daughter. I go to YouTube, press play on my favorite reggae songs and WE DANCE!
How do YOU get a decent workout in when the outdoors or the gym is not an option?

Lots of floor exercises. If time is short I do compound and core only, like pushups, squats, burpees, dips, pullups, etc.

My gym has a roof and walls so I just go there.
