An isolation exercise to develop the deltoid muscles. It also works the lower trapezius muscle and rhomboids, improving posture.
Sit down facing the training machine.
Place your chest or stomach tightly against the machine back and grasp the handles.
As you exhale, pull the handles backwards so that you feel your muscles stretch but no pain in the joints.
Slowly return to the starting position as you inhale.
Do not swing your torso and keep your back straight.
Do not try to push the handles - you risk hurting the ligaments and preventing your muscles from working correctly.
This exercise improves your posture by working the rhomboids responsible for contracting the shoulder blades.
