The pulleys are generally regarded as a safer palliative, more practical but alsoless flexible as dumbbells. More or less sophisticated, they also make it possible to carry out unique Exercises and represent, to some extent, an intermediary between the dumbbells (“free loads”) and the specialized machines (which generally offer a better muscular localization).

The low pulley is used mainly for the various Exercises of inflection of the arms (Curls...), but also of vertical rise in order to work shoulders and trapezoids.
