Losing weight requires perseverance first. Three days of fishing and two days of drying nets are totally useless. You can do 50 sit-ups before going to bed every day. If you get used to it, add more. This is for the fat in the waist and back. If you have fat on your legs, you'd better run. Since you feel tired from running, you can also use the lazy way, that is, when sitting on a stool, lift your legs, then extend horizontally at a 90-degree angle with your upper body, then put them down after 20 minutes, and then change them to half an hour later. If you have fat on your arms, pull-ups are very effective, and this kind of fitness equipment is available in general communities. Or push-ups, it will also work. Try sit-ups. I tried it myself. They are very useful. Typing is difficult. Take it. O(∩_∩)O
