Some people think it's boring and tiring to keep exercising and lose weight all the year round. Can you use the usual manual labor instead? The answer is no, because exercise is systemic, and manual labor is often confined to a certain part of the body. The action is both single and mechanical, and the calorie consumption is very limited. At the same time, repeating certain actions for a long time is particularly easy to make people tired. Excessive fatigue will produce fatigue toxin, which is not only bad for losing weight, but also harmful to the body. Once the body is tired, it needs enough rest to adjust, thus limiting the consumption of calories. Long-term single, mechanical labor will not only bring local fatigue, but also cause tissue damage. For example, farmers generally bend over more, so the waist soft tissue is easy to strain; Typists have to keep tapping the keyboard with their hands every day, so their wrists are easily damaged. Although they don't know how many times they have to repeat their movements every day, the calories they consume are negligible. Exercise is an activity in which all organs participate, which is conducive to the enhancement of cardiopulmonary function, the strengthening of blood circulation and the supply of adequate oxygen. It can not only consume excess heat in the body, but also is not easy to get tired. Further reading: Exercise with the best weight loss effect can reduce appetite.
