Safety is important, so you'll want to make sure you have adequate space to do your workout without risking injury. Make sure you can have any equipment you need, too, and that it's a spot you actually want to spend time in. Do you need a couch, chair, or larger screen? Do you like having a window close by? Once you find a space that accommodates all those requirements, make the effort to transform it into a workout zone when you need it. It sounds silly, but my routine changed immensely once I invested in a yoga mat. There's something about rolling the mat out on the floor that immediately puts me in the right mindset: OK, it's time to work out.
