First of all, what is the state of persisting in exercise for two years? Have you exercised every day in the past two years? Or should I exercise every three to five days? Or don't exercise once every ten and a half months? This is very important, because the body is honest. If you really pay in place, then the body will definitely give you a corresponding return. If you have two years' exercise history, but the number of times you actually exercise in these two years is less than half, then you can explain why it has no effect.
In addition, exercise should be persisted. You may exercise every day for three months in a row, but you don't exercise much for the next six months, so even if the first three months are effective and you rest for a long time, the previous effects will disappear.
Secondly, how much exercise do you need each time? How long do you exercise every time? For example, I may have to gasp for half a day in the 100-meter sprint, but the actual exercise only lasted for more than ten seconds, well, 20 seconds at most. However, it will send a very tired signal to the brain. If this is exercise, it is normal that body fat can't be reduced. Of course, what I said is a little extreme. Maybe you will walk or jog for an hour and a half at a time, but it may not be enough to consume all the energy you consume that day, so you can't expect to lose body fat.
If you really want to reduce your body fat rate, you must do enough exercise every time. For example, you can only jog for half an hour at a time before, and your body is not particularly tired. Then run for another ten minutes, and then walk for another twenty minutes until you feel tired. This kind of exercise can be done every other day. If the body can eat, it is no problem every day.
If you want to lose body fat, don't do too much anaerobic exercise, because it will not only make you more tired, but also be of little use to fat consumption, while aerobic exercise such as jogging can maximize the consumption of excess fat in your physical strength.
Finally, simple exercise can not achieve the most efficient effect of reducing fat, and it needs to be combined with good life rules. For example, although you exercise every day, but take eating too much as an excuse, then the effect of exercise will definitely be greatly reduced.
Therefore, a reasonable diet and moderate exercise, coupled with long-term persistence, can finally achieve the purpose of fitness and fat reduction!
