If you have problems with back you have the backrest more inclined back (then weight of barbells is spread on rest). Effect of exercise is more transferred on upper part of pectoralis but it is not damaging.

You hold barbell with overgrasp and palms are dialled forward. Correct width of grasp is in a moment when are upper arms in one line with shoulders and in elbow is approximately right angle (see photo). Starting position is on thorax under clavicles. You are breathing out and pull the barbell above your head. You are breathing in and return the barbell to the starting position.
