All sounds like good advice in my opinion but I will say from time to time exercises will take their toll on you and you may be forced to up your rest times to compensate. Squats and Deadlifts for me are two key exercises that no matter how much cardio I do still leave me short of breath and almost vomiting. My point is listen to your body if need be. Personally, I like being short of breath and just before vomiting but I have issues.
