Sit down on the Lat Machine and get your knees nice and tight under the leg pads. Grab the bar with your palms facing away from you. Your grip should be wider than your shoulders. This is your starting position.
Pull the weight down all the way until you the bar goes past and under your chin. Then, release it back up until you are back to the starting position. Don't fully extend your arms on the way back up because you should always keep tension in your arms.

SPECIAL NOTES & LEVEL of DIFFICULTY VARIATIONS
To increase the level of difficulty, slow down the movement or select a heavier weight on the weight stack or use a wider grip.
This is a classic machine exercise for the lats and it will carve our your back very nicely. By carving out we mean that you will have plenty of details added to you back which is always a good thing.
One thing this exercise will not do is build slabs of muscle onto your back. If you want to focus on building muscles and getting a huge back you will need to perform exercises that involve the use of free weights.
