Turn for your slim- quick fitness formula

Switching up your workout routine throughout the week boosts the body’s production of metabolism-revving human growth hormone (HGH) to power off up to 6 pounds and 5 inches of belly fat per week. Even better, you don’t have to spend hours exercising to see results. “I’m not an exercise fanatic—with a career and kids, I can’t be,” promises fitness expert Denise Austin. “In fact, I do only 30 minutes of official exercise a day.”

To get the benefits, Denise recommends switching between the cardio, toning and stretching workouts detailed on these pages throughout the week. Beginners should aim to try each type of exercise once a week, working up to two toning and two cardio workouts per week as you get more comfortable.
