Title: Does fat burning really start after 30 minutes of exercise? Introduction: The article challenges the myth that fat burning only begins after 30 minutes of exercise, highlighting intensity and frequency instead.

Life lies in movement. In recent years, a variety of exercise methods have emerged, including aerobic and anaerobic exercises, as well as those utilizing different equipment. Regardless of the form and method adopted, the duration and effectiveness of exercise are closely related. Recently, a common saying has circulated: "Exercise must exceed 30 minutes for fat to start burning." But is this scientifically valid? A reporter interviewed Wu Xinglin, Director of Area B at the Orthopedic Diagnosis and Treatment Center of the First People's Hospital of Yinchuan, to verify this.

Wu Xinglin explained, "This statement is actually a widespread misunderstanding. Fat does not only begin to 'work' after 31 minutes of exercise. In reality, your body starts to utilize glycogen and fat from the very first minute of a workout; however, the ratio of energy sourced from these elements changes based on different intensities and lengths of time. This misconception may arise from the fact that after 20 to 30 minutes of moderate-intensity exercise, the percentage of fat as an energy source reaches a relatively high plateau, making fat burning more effective at that point. Nonetheless, it is not a matter of starting from zero."

The myth that "fat burning only starts after 30 minutes of exercise" has been debunked. For the average individual, how long should each exercise session ideally last? It is suggested that, for public health, the total amount of exercise performed each week is more significant. Wu Xinglin recommends that adults engage in at least 120 minutes of moderate-intensity aerobic exercise weekly, such as brisk walking or jogging, or 75 minutes of high-intensity exercise. This total of 120 minutes can be flexibly allocated throughout the week. For those new to exercise, even sessions of just 10 minutes can be beneficial for health, provided they are active. The key is to start with brief, low-intensity workouts and gradually build a habit.

It is crucial to remind everyone that the duration of exercise does not necessarily need to be longer to be better. The effectiveness of exercise is not determined solely by the length of a single session, but also by appropriate intensity, frequency, and consistency. Extended periods of exercise, particularly in a singular form, can lead to excessive fatigue, joint strain, temporary immune system decline, and even heighten the risk of injuries. Listening to your body is essential; if one experiences significant fatigue, joint pain, or discomfort, it is advisable to cease exercising and take a break. For most individuals, a single aerobic exercise session lasting up to 60 minutes is generally safe. More importantly, proper recovery and nutritional replenishment following exercise are vital.
