■ lose weight? Of course, the longer the better. I'm afraid you have no physical strength. Exercise 1~3 times a day for more than 40 minutes each time. Jogging, badminton, table tennis, aerobics, street PK, outdoor ML, etc ... can be chosen at will according to personal preferences, and it is easy to stick to it if you like. It is suggested that the items should be arranged from weak to strong. If you can't insist, you can go quickly, but don't stop! Only continuous stability can lose weight. In fact, losing weight is not about what exercise you do, but about ensuring that you exercise continuously, stably and a lot.

■ "Why can't you stop for 40 minutes? I am lazy. Can't I have four minutes? In 40 minutes, you are just consuming what you just ate today, the enzymes that break down fat and the fat circulation system. It takes about 40 minutes of continuous exercise to get results. Don't think that after a few minutes' rest, no one will know that the production of those enzymes will be interrupted and then started again. Start with easy projects in the first 40 minutes, and practice hard on high-consumption projects after 40 minutes. All you need is persistence.

■ "Then why go? How soon? I can run very well ... "Because many people can't score 40 points in running and jumping, they choose to walk fast, which is also the easiest project to achieve continuous consumption. The simplest but not the most effective. The most effective are jogging and skipping rope. Therefore, if you want to lose weight, you must stick to it. The most effective is not necessarily the most suitable for you. Of course, the speed is better than that of Liu Xiang. You asked again, "Isn't swimming the best way to lose weight? Swimming resistance and heat loss consume a lot of physical strength and heat, and it is interesting, with even resistance, which makes people less tired. However, due to time, place, climate and other reasons, although wearing shorts can become a "slimming swimmer", it can't get out of the swimming pool. The feasibility should be considered as appropriate, and it should be remembered that swimming is not soaking in the hall.
