Professional athletes never train at maximum intensity all the time, so I don't know why recreational athletes assume they can.
Then again, recreational athletes generally represents people trying to stay in shape, not actually trying to be athletic.
At any rate, HIIT and 'standard' cardio are the same thing repackaged. It's not magic.
In research, HIIT has been shown to burn adipose tissue more effectively than low-intensity exercise"”up to 50% more efficiently. In other words, HIIT speeds up your metabolism and keeps it revved up for some time after your workout. The bottom line is HIIT training burns a greater number of total calories than low-intensity training, and more calories burned equals more fat lost. What I'm suggesting is you forget about the "calories burned" readout on the stairstepper or Lifecycle; if you practice HIIT training, the majority of calories burned will come after your workout.
