Many JMs know that a balanced diet along with appropriate exercise is the best way to lose weight. However, not all exercises in weight loss methods are helpful for weight loss. Inappropriate exercise can even make you fatter. Below, 39 Weight Loss Network, a professional weight loss website, lists three types of exercises that are not conducive to weight loss, hoping it will be helpful to you.

1. Excessive Exercise

When the amount of exercise is large, the body's required oxygen and nutrients as well as metabolic byproducts increase accordingly. This requires the heart to strengthen its contraction force and frequency, increasing cardiac output to transport these substances. During high-intensity exercise, cardiac output cannot meet the body's oxygen needs, causing the body to be in an anaerobic state due to oxygen deficiency. Anaerobic metabolism does not primarily use fat as the main source of energy release but mainly relies on breaking down stored glycogen in the body for energy release. In an oxygen-deficient environment, fat is not only unable to be utilized but also produces some incompletely oxidized acidic substances, such as ketones, which reduce the body's exercise endurance. After short-term high-intensity exercise, blood sugar levels decrease, and reduced blood sugar is a significant cause of hunger, leading to increased appetite, which is extremely unfavorable for weight loss.

2. Too Short Exercise Duration

During aerobic exercise, the body first uses stored glycogen to release energy; after about 30 minutes of exercise, it begins to transition from glycogen energy release to fat energy release; approximately after one hour of exercise, the energy required for exercise is mainly supplied by fat. For example, in the commonly seen aerobics for weight loss and body shaping, the duration is usually around one hour. That is to say, when fat just starts to decompose, people stop exercising, and the weight loss effect naturally goes without saying.

3. Rapid Explosive Power Exercise

Human muscles are composed of many muscle fibers, mainly divided into two categories: white muscle fibers and red muscle fibers. During exercise, if performing rapid explosive power training, the mainly exercised fibers are white muscle fibers, which have a relatively thicker cross-section, making the muscle group prone to develop thick and strong. Using this method for weight loss may make you look "thicker."

In summary, to achieve the goal of full-body weight loss, you should engage in low-to-moderate intensity, long-duration (more than 1 hour) aerobic metabolic whole-body exercises with a heart rate of 120-160 beats per minute. For example: aerobics, slow long-distance running, long-distance swimming for a long time.
