Surprising study: One minute of exercise at 90% of your max heart rate followed by one minute of rest ten times (twenty minutes total) had significant health benefits. This is true even if done once or twice a week, you aren't fit, and are a cardiac patient!

Also people seemed to like the more intense shorter workout better than a longer more moderate one. Seems like it is worth a shot! What have you found the best way to stay fit in the minimum time?´╗┐
