<human>:  What is the best exercise regime to reduce belly fat?
<bot>: The best exercise regime to reduce belly fat is a combination of cardio and strength training. Cardio exercise such as running, biking, or swimming can help burn calories and fat and increase your metabolism. Strength training can help build muscles, which burn more calories than fat does. It's important to ensure that you are putting in enough time for both types of exercises. Aim for at least 30 minutes of cardio and 15 minutes of strength training a day. Additionally, eating a balanced diet that's rich in protein and low in carbohydrates can help you better achieve your goal of reducing belly fat.
