Sit on the bench pad and secure the bar attachment on the GR8Flex. With an erect posture and a straight back, grab the EZ bar attachment with a supinated hand position. Keep your shoulders retracted and back neutral throughout the curl. Start with your arms out in front of you and finish by bringing the bar to your shoulder level. Allow your feet to levitate so that you are able to perform the movement freely. Avoid leaning forward or backward during the movement by allowing for a brief pause at the beginning and end of every repetition.
