I dont believe in over training, I believe in undereating. If your body is able to recover and you can physically do it then shit go for it. Any one that says you have to take a week off per muscle or ect is full of shit. Every one is created differnt and if your body is capable of that then go for it. If you feel like your being drained up your carbs and protein. Keep your fat really low in the diet, so you burn off fat. If I am bodybuilding I like to go no carbs, with fat and high protein. But with your work outs I would go no fat, high carbs, and high protein. Force your body to burn its own fat as long as your utilizing your carbs.
