How long should I wait to do cardio workouts after I done heavy weight lifting workouts?
I read some where in a magazine that if you do both you will mix up the growing dna genes and the body will not build muscle because it gets confused from the cardio workouts, maybe?

1. You should alternate days. Two days weight, two days cardio, two days weight, etc. And you should only do about 30 mins of cardio. The cardio actually stops having a positive affect on your body after 45 mins.
