Problem Areas

I am really hoping to work on problem areas...  I want to work on toning up my arms, my thighs, calves, and stomach.  I also want to work on my flexibility and endurance, because I am working on getting my fitness level up to the point that I can do the FitnessBlender 1000 calorie burn work out.  I really want to be able to do that, but there are things I need to work on first, before I can start doing that.
