Swimming is a very efficient exercise to lose weight, which can protect your knees and prevent them from being injured. If you want to lose weight by swimming, you must stick to it for two months. The main reason why swimming has a good weight loss effect is that the resistance when people are active in water is 12 times that when they are on land, and their hands and feet can move at the same time, and many parts can get great exercise, such as back, chest, abdomen, buttocks and legs. From the beautiful lines of swimming kinematics, we can see how good the effect of swimming exercise is.

Don't underestimate swimming, it is a very intense sport, and the heat transfer speed of water is much faster than that of air. To put it bluntly, people consume much more calories in water than in water, and the excess fat on their bodies will slowly dissolve when swimming. Relevant data show that people who swim in water for 20 minutes consume the same amount of calories as those on land 1 hour, so the time spent swimming to lose weight is half of normal weight, and the effect is good.

The speed of swimming metabolism is quite fast, basically it takes only half an hour to consume 1 100 kilojoules of heat, and even after swimming, the body's heat is still consumed for several hours. Some people lose weight by swimming. The reason is probably that they don't exercise enough and need to extend their exercise time. If you want to lose weight, you must swim for more than 40 minutes at a frequency of 3-4 times a week.
