three days a week and resting yourself for two...there's no way you're overtraining. the symptoms of overtraining are as follows.
-you're exhausted most of the time, but you have trouble sleeping at night.
-you're achy all over, beyond the specific fatigue and lactic acid you feel in your target muscles from individual training. you'll feel sluggish almost like you have a light case of the flu
-you're getting weaker...dropping weights or reps. not necessarily a plateau, but more like a general pattern of decreased strength over time.
-you're injuring yourself frequently in small ways, like a nagging or reoccuring pain in a body part that shows up even when you're not training it.
-you're immune system is down and you're catching colds, sties, cold sores and that sorta thing. you're body's overwhelmed because you're taxing your body too much.
if this is you, here's what to do about it:
-cut back on cardio...lower intensity casual cardio for like 15-30 minutes and keep it to like twice a week. just enough to get the heart rate up but you're not going full bore and killing yourself
-take 3 days off from training. don't scrap the program all together but your body is telling you it needs time to catch up to you and recuperate. after all, you grow when you recover, not when you're training.
-eat better quality food-healthy fats, bump up the complex carbs, whole food protein, and make sure you're taking a multivitamin.
-call your girl over and get a massage (happy ending is optional)
