those saying disregard cardio and just lift, obviously haven't stuck to a hiit cardio program for any length of time. in fact, i did the opposite..i gave up squats for sprints and my legs are more muscular than ever, im leaner, and most importantly my heart is healthier.
if your're man enough (it sucks balls) do all out sprint intervals in the mornings before you eat, 2-4 times a week...take approx. 50-100 mgs of caffeine (less if your sensitive), 2-3 grams of leucine, and lots of water first.
