I prefer to do short periods of cardio with high bpm than looong tiring sessions with low bpm. Remember, in the end all that counts is the calories taken versus calories burned. Short periods of cardio with high bpm will not take away your muscles. Also, it will boost your metabolism better than low bpm workout. After a high bpm workout your body will "run" faster longer than after a low bpm workout. The exact time of doing the workout is not the ONLY time you burn calories.
