Cardio isn&#x27;t powerlifting. Every single workout is more or less the same. I worked out three times a day on cardio because the balls of my feet would get irritated after about 45 minutes, so I couldn&#x27;t just do 3 hours in one sitting. The calculus changes when you&#x27;re doing 14-21 workouts a week.<p>I <i>want</i> to do more cardio. Even now, I wish I could get on the machine. I&#x27;ve come to need it just like my morning coffee. I have to keep myself away from it so I don&#x27;t get injured.<p>It will take me probably another year before my body adjusts to the massive amounts of cardio I want to do.
