I only go to the gym in the winter. We are sometimes buried under snow and cold here in Flagstaff in the winter and since it is dark when I get off work, Yes, I do work out in the gym in the winter. A little weights, a little yoga and a lot of spinning classes.

I just can't hack it after the weather gets nice though, gotta ride (mountain and road, hike, and kick back outdoors - That is where it is at!
