How to safely perform overhead press?

In every exercise we perform, we should always emphasize safety when performing, especially when it comes to exercises where we activate a larger number of muscles.
Which are those exercises?
Most of these are exercises for the development of shoulder muscles, with a military press bar, thrusts overhead with puckers, kettlebel and other props that pose external stress and thus put additional stress on the muscle for growth purposes.
What should I look for?
Most attention should be paid to the lumbar spine (popularly called the lower back) and which position is during exercise. Insufficient mobility in the shoulder or compensator has twisting in the lumbar region to allow the cargo to rise above the head, not in front of it.
The problem with shoulder mobility can be gradually solved by stretching the surrounding structures, and if you can not perform a movement because of pain, it is necessary to perform a review and dedicate primarily to the removal of pain and kinesitherapy. Here are things individually so there is no general advice but every case for themselves.
Conclusion
Over-head presses are a complex exercise where it is very important to have sufficient mobility in the shoulders before we run it, and since there is a large number of muscles involved in the exercise and at one point we hold the weight above the head, it is necessary to ensure proper performance before working with larger weights.
