Brief introduction of kneeling cross-arm training machine (that is, big bird)

Cross-arm training machine is also called gantry. Its main operation is that the big bird exercises the width of the pectoral muscle, which can make the visual effect more full, but it has no obvious change in the strength and thickness of the pectoral muscle.

Replace the handle with a thick rope with a bent rod, and you can do chest pull-down and other actions (other side actions can be mastered by the user). The main training of triceps brachii is to assist the flexion and extension of barbell arm and parallel bars arm. The best way to shape the triceps brachii is always to carry weight freely, so this kind of instrument can't be used as the main content, and it is usually used at the end of training.
