Answer:
<h2>Awkward postures.</h2>
Explanation:
We can define awkward postures as those body positions that deviate significantly from the neutral axis position or they are maintained for a long period of time. For example, the neck have a neutral posture is you don't move it, because you are in the neutral axis, if you move a 15 to 30% more often, you will be able to do it, but if you move more than 50% of the time, you will be in a awkward posture.
Same thing with back postures, you can bend a couple of times, but if you do it all the time, soon you will be having pain, because you are often putting your back in a awkward position. Another case is when you bend a few times, but you do it extremely, in such flexible ranges, soon or later you will be having pain.
