Walking burns excess body fat. However, it does not target the fat around your waist because you cannot spot-reduce. To burn fat around your waist — and everywhere else on your body — do at least one hour of brisk walking every day. Vary your walking route, pace and style to add new challenges, build muscle, increase your endurance and boost fat-burning. If you have injuries or medical issues, speak with a doctor before implementing a vigorous walking regimen.

To burn fat effectively and trim your waistline, you need to walk quickly for a sustained period. Strolling or stopping and starting do not elevate your heart rate enough to burn many calories. Walking a 30-minute mile burns only 180 to 270 calories per hour, while walking an 18-minute mile burns 275 to 415 calories in one hour. Walk a challenging 12-minute mile and burn 585 to 875 calories in one hour. If you burn 500 calories walking every day, you lose 1 lb. of fat per week.
Vary your walking workout, burn more calories and strengthen your abdomen, thighs and calves by climbing hills, moderate grades or stairs. Climbing stairs burns 660 to 980 calories per hour. Hiking up hills burns 440 to 655 calories per hour. Add a weighted pack, and you burn 510 to 765 calories in one hour. In addition, the muscle tissue you add to your lower body raises your resting metabolic rate so you burn more calories even when you're not exercising.
Increase the fat you burn during your walking workout by doing speed intervals. Warm up by walking slowly and then moderately. After 10 minutes, walk vigorously for five minutes. Then, break into a sprint, either running, jogging, race-walking, jumping rope or doing another intense activity. After 30 seconds to one minute, slow down to rest, but keep moving. Return to your vigorous walk. Do speed intervals every five minutes and you spike your heart rate, build endurance and burn more belly fat.
Engaging Your Core
Using proper form during your walking workout reduces your chances of injury, and it also strengthens your abdominal muscles so you look slimmer around your waist. Inhale deeply and contract your abdominal muscles. When you exhale, keep your muscles contracted. The contraction supports your back so you stand up straighter while walking. You gradually increase your core strength, adding muscle tissue and toning abdominal muscles.
