Adjust the cable machine's handle to shoulder height. Grab the handle and take two to three steps away from the machine. Then, square your hips and face away from the machine. Make sure you keep the cable at shoulder height and when you start your first rep brace your core to avoid swaying left or right. Keep your core engaged and focus on engaging your chest muscles to push the cable in front of you and back when you bring the handle back to your chest make sure it's with control and through slow movements. Make sure you're engaging your chest and repeat the movement
