Let's see, my routine is pretty set right now, so Christmas is Wednesday, which would be back and arms.
I have no problem working out on Christmas or other holidays. That said, I also love family time and have no problem skipping a workout to be with my two boys, wife or extended family.
So it sort becomes an issue of whether I find the time. If, for example, my boys are playing a new video game they got from Santa or a family member, than I could escape to the basement and get in my workout.
How about you Ratcat?

Do not be deceived, my beloved brothers. Every good gift and every perfect gift is from above, coming down from the Father of lights
