Here is another great workout challenge posted by our friends at Curvy, Confident and FIT on Facebook. It’s a core challenge! You can add this workout to your “1 hour per day minimum” workout goal for our January 2012 Challenge. Planks, crunches, mason twist, supermans, and more. If you need to see how the exercises are done, just do a search for them on YouTube or Google. They are common exercises.
