Winter workouts- Considering many of you are in winter right now, how do y'all stay active in the cold weather?

Personally, not only are gyms are out my budget right now, my area gets blizzards and over 10-20 inches every year in December- January making it hard to leave the house for anything other than work and groceries. 

When stuck in the house I usually just walk up and down the stairs. 

What about you guys?
