Fitness is a step-by-step process. It is better to have a group. If you can insist on going to the gym, you'd better get a card. There are many people who lose weight with you, and it is easier to stick to it. In addition, you can't just do aerobic exercise to lose weight, so you lose fat and muscle, which consumes 20 times as much calories as internal organs. You also need to increase some muscle content, need anaerobic training, and supplement some protein intake (egg white, protein powder, skim milk, lean meat, etc. ), can improve the basal metabolic value, not easy to rebound. If you only do aerobic training, you will lose more than 5 kg every month, and it is easy to rebound.
