I know for the IMAX's, Cathe recommends one or two times a week, and no more. I guess I always thought that was due to the high impact nature of those workouts. Is there a reason NOT to do interval training whenever you do cardio, like using iTrain or cardio coach for running or ellipticizing? What if you do cardio 6x week? Can you interval train that much? TIA
