Achieving a toned stomach involves reducing body fat and building muscle in the abdominal area. This can be accomplished through a combination of diet and exercise.
A healthy diet that is low in calories and fat and high in protein can help to reduce body fat. Regular exercise, including both cardiovascular activity and strength training, can help to build muscle and burn calories. In addition, some people may find that using a waist trainer or other abdominal support device can help to improve their posture and support their back, which can also contribute to a more toned appearance.
