It is possible to burn fat without doing cardio exercise, but it may be more challenging. Cardio exercises such as running, cycling, and swimming are effective at burning calories and fat, but they are not the only way to achieve this.
Strength training exercises can also help burn fat by increasing muscle mass and metabolism, which can lead to a higher calorie burn even when at rest. A combination of strength training and cardio exercises, called high-intensity interval training (HIIT) can be also very effective in burning fat, as it alternates periods of intense exercise with periods of rest.
A healthy diet, which includes a balance of protein, carbohydrates, and healthy fats, can also play an important role in burning fat. By reducing your caloric intake and eating nutrient-dense foods, you can create a calorie deficit, which can help you lose fat.
It is important to keep in mind that losing fat is a process that takes time and effort. To see results, consistency in exercise and diet is key, as well as being realistic with your goals and not expecting instant results. Consult with a healthcare professional or a certified personal trainer to design a workout plan that fits your needs, goals and abilities.
