There are some thoughts that come to mind, and one is with your nutrition. I had a peek at your Nutrition Tracker, but you don't seem to use it often - do you record elsewhere? Ensure that you are eating enough to sustain your exercise at the gym. Remember, too few calories can cause this. Below is a link that may give you ideas for that: www.sparkpeople.com/resource/nutrition_art
Are you getting a good mix of nutrition, as in plenty of lean protein, lots of fruit/veges, and in a variety of colour, and complex carbs (in the form of wholegrains, etc.)
How much sleep do you get over-all? .... AND is it quality sleep?
Do you have any health conditions - i.e. Diabetes etc., that could contribute to this problem?
Are you on any medications?
Apart from the work-outs, are you doing anything different on those days, than you do on the other days?
