If you think Dexter does no cardio, look at these:
Before
After
Do you really think he always did this?
The only way I can see ANYONE getting by with absolutely ZERO cardio, is to increase the fat burning drugs (clen, T3, ephedra, etc...) to a seriously dangerous dose. Then again, who am I to talk? I've taken Bronkaid, 400mg of caffeine pills and a triple shot Rockstar as "one dose" numerous times in a day.
