Ditto. I've gotten into the habit of overworking my legs. Deadlifts, squats, martial arts training, and sprinting... oy! Two days is definately my max for days off. Like others have mentioned, the most difficult part for me is sticking to my off days.
Because I'm crazy I purposefully overtrained during this brief holiday respite. Five straight days of total body workouts, with moderate to high intensity cardio everyday. I've been consuming 5000 to 6000 calories, and amazingly, I've been recovering quite well from the workouts! I even set a new personal best on my squat while also cranking out more HIIT sprints than I ever have. Oooh, if only I could sit around, play guitar, read T-Nation, read, and write all day.
