definately dont need one hour cardio this far out. if anything i'd be using the last 3 weeks or so just to try and add some more quality mass, start eating healthier foods, things that you could incorporate into your diet and then start tapering down with your calories, or however you plan to do it. you said you were carb cycling. in my experience, just taking out all refined sugar from my diet makes a big difference. but to each his own i guess lol
