When using a computer (basically, you don't need to tap the keyboard, but use the mouse more), you can support your arms on the desktop (but you can't shrug your shoulders), move your chair away, watch the computer, and do simple exercises, such as walking back and forth (highly recommended! There are many ways to lose weight and the effect is good! ), bending over (the desktop is lower than the chest), stepping, squatting, and jumping left and right legs alternately are all good! Especially after eating, you can't do strenuous exercise, just do some small exercises of your lower limbs!
Come on! This is my personal experience, and I will share it with you ~'
