its mostly diet unfortunately or fortunately however you look at it! Protein intake and just proper nutrition,not over doing the calories to keep the badness form happening to legs and buts and stuff.
I have cardio queen-itis in my genes as well. and was an addict..and can get hooked now and then..but it leads nowhere really special...just sweaty.
BUT as a general rule if you are doing pushing yourself enough with wt's you can ditch conventional cardio, just watch your food. I have trouble not doing SOMETHING that makes my heart rate up. Complexes, reps, things that make you have your arms over your head seem to work for me.
