To get results from exercise, intensity and frequency are more important than duration. In fact, intensity and duration are inversly related. In other words, if your exercise duration is shorter and your intensity higher, you get the same, if not more effects from exercise. If you are running short on time, like most individuals are, then exercise sessions of a shorter duration make sense.



Scientific experiments have proved that this is an effective strategy for weight loss:

• More Miles. In a University of Nebraska-Kearney study, overweight walkers who did two 15-min bouts, 5x/wk, nearly doubled their weekly mileage compared with walkers who walked 30 min, 3x/wk.

• More Calorie Burn. Whether you do your workouts all in one shot or break them up, you burn about the same amount of calories. But what happens AFTER is a different story.

• Better Recovery. A long, tedious, 60-90 minute workout will burn you out physically and mentally fast. Concentrating your workouts into 30-35 minutes allows your muscles to recover between workouts, and to work your body more frequently.
