Workout ideas for indoors?

I have all my equipment set up outside in my back yard. I keep my mats, weights, bands, and pull-up bars outside. Does anyone have ideas about some indoor idea for when its raining, or bad weather?

Push ups, squats, good mornings, if you have enough room to practice stand up, it's great cardio

dumbbells, TRX Suspension, Calisthenics, stretching, rolling around on your floor .. lolol
