However, Lu Yifan, a professor at the Sports Medicine Research Office of Beijing Sport University, reminded that it is best for the elderly not to try too steep slopes, whether it is treadmills or sports venues such as parks and playgrounds, so as not to damage their knees. If you find yourself gaining weight after an exercise, it may be caused by drinking more water after exercise; If you gain weight after a period of exercise, it may be that the proportion of muscle has increased and the proportion of fat has decreased. Because of the high density of muscle, the same volume of muscle is much heavier than fat, so although the weight has recovered, it actually achieved the effect of losing weight. "Any long-term exercise is effective for weight loss, and weight loss is also a gentle process. Generally speaking, it is more appropriate to lose weight within 1kg per week. " Lu Yifan said.

The Los Angeles Times pointed out that the intensity of exercise determines the purpose of your exercise. Losing weight requires low-intensity and long-term exercise, which can consume fat and calories, while high-intensity exercise makes your muscles more and more developed, which is why some people get thinner and thinner, while others get stronger and stronger. The fundamental reason is that the intensity of selection is different. When people do low-intensity exercise, it is mainly fat that provides energy. Therefore, burning fat on the treadmill will guide people to do low-intensity exercise for a long time. It is found that about 50% of the calories consumed by walking on the treadmill come from fat burning; If you run fast, only 35% of your calorie consumption comes from fat burning. If you want to double your calorie intake, try climbing fast. Its exercise intensity is between fast walking and fast running, and it can consume more calories in the same time, reducing both fat and weight. Compared with running on the ground, I exercised the muscles of my back, buttocks and thighs.

Core Tip: Summer is a good time to lose weight, but the effect is not obvious after many people go to exercise, mainly because the method is wrong.
