If you can hold on for 15 minutes, I don't think you are standing on a physical pile.

You can choose the following methods according to your own situation:

1. Watching TV while standing on the pile, although the eyes are moving, which affects many elements of the pile, this method has been confirmed by many people and is really effective in prolonging the time of standing the pile. When the time can be extended to more than half an hour, replace the TV with a clock and put it in front. You can hold back at the last few minutes, but when you get used to standing for forty minutes, remember to throw away the clock, too. This is suitable for the light-hearted stacking method.

The second is to rest in the middle. You can stand 15 minutes, walk 15 minutes (don't do anything specific), and then stand 15 minutes. This can prolong the physical and mental strength needed to stand on the pile.

The third is the overall effect, which is what you said, divided into morning, middle and evening, but if you stand like this, it may take 15 minutes, and each station can't stand for 30 minutes. After that, you can only stand for one or two minutes at a time as long as possible to improve your strength.

In fact, everyone standing on the pile knows that when you have the idea of standing for a certain time, the last ten minutes are often the most difficult. Some people even said, "Standing on a pile means standing for the last ten minutes." This kind of difficulty is not physical, but directly reflected in your heart, so people who have experienced it will say that standing on a pile is a bitter thing.

After standing for half a year, we should get into the habit of not looking at the time, and stand as long as the time is loose and willing.
