Super Short, Intense Workouts Won't Help You Lose Weight
Super short workouts sound fantastic. Who wouldn't want to pack

The math doesn't even come close. Any runners who exchange their four-times-weekly six-mile runs for four seven-minute workouts are going to burn at least 1000 fewer calories per week. Which will lead to a weight-gain of 12+ pounds in a year. Minimum. In one year. Try multiplying that by a couple of years.

You'll only get more bang for your buck with that approach. Otherwise, you have to put in the time.
