Hi I'm just starting but consider myself in decent flexible shape.  I have just gotten the belly fat and "granny legs" along with the upper arms I'd like to get toned.  I'm 63 and have been exercising since I was 10.  I'm starting with the 5 day workout and have a question about after I complete that.  Do I just keep repeating this 5 day workout for a period of time? Or is there a format of videos I should do targeting the specific areas.  Its a little overwhelming and I'm not sure how to proceed.
