I'm honestly a believer in cardio i think its good for you all around, and i believe it reflects back on weight lifting, but thats just me. And yeah that sounds alright to me, but be warned, if you're running in the morning without eating any meals, you're going to be burning muscle for energy, not fat. ESPECIALLY first thing in the morning. they call it breakfast, because its your first meal, and your body is still burning calories at an accelerated rate (fast) in the morning, so that first meal BREAKS your fast, so you stop losing precious muscle tissue for energy. and most the calorie burning takes place a couple hours after your cardio session, not during. Just make sure you're not starving yourself while you're doing your cardio, or any workout for that matter, and you should be alright.
