i dont need help with what types, but input on it wouldnt hurt. My main question is when to do cardio, by the time i am done lifting i am fucking beat so i never have the drive to do cardio. My new schedule would allow me to do cardio in the am and lift in the PM. What you guys think about fasted AM cardio, how much is enough, how much is too much? Do you eat or drink anything before doing to to preserve mass? I am in need of the guys that know the science with this shit to help me out as i am still learning on that aspect.
