The close-grip variation.
Make sure you grab one of the handles to close the rip handle, set it up, put your feet even on the platform, knees slightly bent. Grab the handle and make sure your back is straight the entire time. Keep your elbows slightly bent, the chest is out, and the shoulder blades are back and down. As you pull the weight back, drive back with your elbows to a 90-degree angle, and focus on squeeze your shoulder blades.
The wide grip targets your biceps and the middle range of your back. Focus on bringing the bar towards your belly button. Just like the close grip, keep the shoulder blades squeezed, elbows slightly bent, chest out, and knees slightly bent.
