Please take a second to let your arms hang down and look at your wrists. How are they rotated? No kind of horizontal bar or machine handles lets you train at this angle - also called the neutral grip position. The potential result according to science: shoulder, wrist and elbow injuries. But not only.

Your muscle growth is going to suffer too, since you are not training at angles that hit your back and shoulders most efficiently. In addition, by always choosing the same training positions, you will only activate those same muscle fibres again and again.

Static/ fixed bars in general are further contributing to these problems. From an anatomical point of view, the optimal pull movement should involve rotating the handle from the overhand grip (palms facing you) to the underhand grip (palms turned away).
