1. Burn calories

Cardio exercise is an effective way to burn calories and create a calorie deficit, which is necessary for weight loss. Thakur says the more calories you burn, the more weight you can lose. So, running, cycling, swimming and rowing are great for burning calories.

2. Increases metabolism

Cardio exercise can boost your metabolism, which is the rate at which your body burns calories at rest. Regular cardio exercise can increase the number of calories you burn throughout the day, even when you’re not exercising.

3. Reduces body fat

When women think about weight loss, it’s mostly the abdominal area that they’re usually concerned about. The good news is that cardio exercise can reduce body fat, especially in the abdominal area. Losing fat is essential to weight loss because fat is a calorie-dense substance, and losing even a small amount of fat can have a significant impact on overall weight loss, says the expert.

4. Improve insulin sensitivity

Cardio exercise can improve insulin sensitivity, which is the body’s ability to use insulin effectively. Insulin is a hormone that regulates blood sugar levels, and when it works properly, it can help the body use glucose (sugar) for energy instead of storing it as fat.

5. Reduces stress

Cardio exercise can help reduce stress levels, which can contribute to weight gain. Stress can cause the body to release cortisol, a hormone that promotes fat storage in the abdominal area.

Effective cardio exercises for weight loss

While running is a great cardio exercise that can be done anywhere, anytime, there are more options. Let’s take a look!
