Work Out Day-Cardio/Arms/Chest/Back

I just went through my history and dang, it's been a while since I actually worked out arms. Bad me. Today marks my last official gym day. Both my kids are off for Christmas vacation from school and I don't have childcare covered at the gym for my son. So, I will really have to step it up with walking, jogging, pilates and other home exercise to maintain where I am at right now or try to lose. I know it will be a huge challenge considering that this is a horrible time of the year as it is to try to diet and exercise. Just wish me luck.
