Be a healthy and fit role model for my 6 year old son, so that I can teach him good eating habits, all the sports I like, plus learn a few new ones with him!

My biggest obstacles: eating while at work!!! And I am surrounded by sweets at work (I work for a gourmet food company with an R&D kitchen and 3 wonderful pastry chefs, and have chocolates on my desk at any given time as samples).
I have a sedentary job and don't move enough.
My husband, who is a chef and cooks the most delicious, unhealthy food :-)
Motivation: I need a good kick in the rear sometimes!

How to overcome the obstacles: I will try to add more activity to my day.
I will have apples or veggies every time I am tempted to eat junk at work.
I will do 10 to 15 minutes of easy cardio every morning to get the blood flowing.
Hopefully this group will hold me accountable and we will all support each other!
