One: The chair sits in the front third.
This posture can avoid being too comfortable lying in the office chair, so that after sitting for a few minutes, you will feel as if your whole body is burning.
Two: please hold your head up and hold your chest in a sitting position.
When you deliberately hold your head up and hold your chest high, you are unconsciously eliminating calories. In the long run, your figure will be in a better curve. Shaping a perfect figure is very beneficial to really forming good habits.
Three: Take a big bottle and drink plenty of water.
Drinking water really enjoys the pleasure of being thin, and it is not hard or easy to persist. Drinking more water can promote metabolism, which is a great way for office workers who don't exercise. And drinking more water has another advantage, that is, you will always run to the toilet, which virtually increases the number of walks.
