Don't worry, there's a way to fix it if you have this "dead butt" syndrome.
Regularly get up from your chair during business hours, it is best to set the phone alarm to remind you of the campaign time. Stand up, walk around, and do some stretching.
Sit in the correct position, adjust the height of the chair so that the toe of the big toe must touch the floor.
Exercise: Squat, lunge or deadlifts (weightlifting squat) are all exercises that have a great influence on these muscle groups.
If you don't have time to practice, just stand up, "tighten" your buttocks for 5 seconds and then release them, repeat 10 times throughout the day, your buttocks will live up for a short time.
