Less body fat means you can see the abdominal muscles.
As you are a novice in fitness, you can do some simple anaerobic training first, and then do an hour of aerobic training, which can not only reduce fat, but also preserve muscles to the maximum extent.
As for what to worry about, even if you lose weight and exercise your muscles, it won't look good. As long as you lose weight, you will look good with muscles. Especially fat people, they have a lot of muscles in their bodies.
Extended data:
1. Aerobic exercise: refers to physical exercise carried out by the human body under the condition of adequate oxygen supply. That is, in the process of exercise, the oxygen inhaled by the human body is equal to the demand, achieving physiological balance.
Simply put, aerobic exercise refers to low-intensity, rhythmic exercise, which lasts for a long time (about 30 minutes or more) and has moderate or upper-middle intensity (60% to 80% of the maximum heart rate).
2. Anaerobic exercise: It comes from the classification of skeletal muscle metabolism during human exercise. At present, the concept of anaerobic exercise is mainly evolved from anaerobic metabolic energy supply system. For example, anaerobic exercise refers to the movement of human muscles in anaerobic energy metabolism.
But what we think of as anaerobic exercise in our daily life refers to the high-speed and strenuous exercise of muscles in the state of "hypoxia". Anaerobic exercise is mostly exercise with high load intensity and strong immediacy, which is difficult to last and the time of fatigue elimination is slow.
