Look at people like McCarver, Piana, Rhoden, Meadows, Kali Muscle, et al.  Being ripped and/or able to perform in the gym is no sign your heart is in good shape - even if it's cardio!  If people have a restless night, or snore a lot, they wake up with darkness under their eyes due to lack of oxygenation of the blood.  So if workouts are causing the same, what's that indicating..?
