Sitting, be sure to have a back at right angles to the thighs. The latter will also be at right angles to the calves, the shoulders, pulled back, the head, raised proudly, the neck and back, straight and calves, parallel to the back .
Have a parallel back to the file. During long sitting stations, the bust tends to lean forward. Always remember to sink into your seat and keep your back parallel to the back.
Sit on your hands. It’s a test of whether you are standing upright in a sitting position. Slide your palms down with both hands under your buttocks on each side of your body. Find the most comfortable position, one that puts most of the weight on both hands. When you feel the weight is that you are in the perfect position.
Have a good position of the legs and feet. Your feet should lie flat on the floor. Never cross your legs or your feet: your thighs should be parallel to the floor
If your feet do not touch the floor, install a footrest.
4 Adopt a seat that requires you to have a good position. There are now ergonomic and height-adjustable seats. Choose one that provides true lumbar support. In addition, the choice of a seat depends on the size and weight of the person If you can not buy an ergonomic seat, put a small cushion against your seat that will marry the curve of the lumbar.
Adjust the height of your monitor. In the office or at home, be sure to align the center of the screen at eye level. Thus, you will have to hold your head upright. Conversely, do not put it too high to not have a sore neck .
Of course, you can play on the height of the monitor, but also on the height of your seat if it is adjusted.
Set your seat. Your forearms should rest freely on the worktop, the angle at the elbow should be about 90 °. If your arms are too loose, you are too far from the keyboard and if your arms are too bent, you are too close or slouched.
Adjust your car seat. If you are traveling long distances, adjust your seat depth and height. Adjust it deeply so that your legs are at a 100 ° angle to the knee. At the elbows, your arms will make an angle of 120 °, the backrest will be slightly inclined backwards .
Support your lower back. If your seat is not ergonomic, slide a small cushion under the lumbar. Adjust the head restraint so that your head touches it or is not far away (less than 10 cm). The upper back should rest on the backrest, the lumbar supports the padding and the head rests on the headrest.
In this position, the knees are at the hips, perhaps slightly above.
The same goes for your safety in the event of an accident: the airbags have been programmed for people who are properly installed behind the wheel.
Take breaks. If you sit for hours, it is good to get up regularly to take a few steps. Get up every hour and stretch, also walk for a few minutes before resuming your activity .
If you have a busy business, do not hesitate to program, on your smartphone for example, all your stops.
Breaks are important to restore tone, because the body always adapts badly to static positions, even if they are necessary.
