DAREBEE Workout: What it Works
You wouldn't normally think that the sofa is a place you'd go to when you need some exercise. Normally it isn't. But a lot of us are spending quite some time on our sofas so being able to do something there is a win that's too good to miss. Cozy Up is a sofa upper body workout. It will stop you from getting rusty and you can do it any time. 
Extra Credit: Do it before and after watching a movie.
