OK. I am constantly looking for things to do to challenge myself. I know some people who do a plank a day and see how long they can hold the pose. I have been doing it a few times a day (my favorite is during commercial breaks at night) and using my stop watch on my phone to see how long I can hold it before my arms start uncontrollably shaking. :) Give it a try. Challenge yourself!
In the craziness of this time of year, it is important to stay on track. It is perfectly fine to go crazy and have diet cheat days....just not an entire diet cheat season. Keep your eye on the prize and remember why you decided to be healthy in the first place.
