We mortals that are aware that too much activity is as bad as too little, that the first thing we have have to do following a workout is recover, should also be aware how much activity is required to give a training effect. Cooper, in the New Aerobics for Women, found that maintaining a heart rate averaging 150+ beats per minute was only necessary for 12 minutes (including 2 minutes warm up), or 140+ bpm for 20 minutes, or 130+ bpm for 45 minutes, or 120+ bpm for 90 minutes.
