Article: One of the most effective ways to work your lats is making use of a weight machine at your local gym. Exercises involving weight machines are great for the lats.  A weight machine is a kind of gym equipment where weights are attached to a bar that the user pulls up and down to help build muscle. A weight machine is often the best way to start lifting weights if you haven't before.  Usually, you sit on a moveable seat and pull the bar down while squatting. The seat and level of weight may need to be adjusted for your size and fitness level. Talk to an instructor at the gym if you have any questions about adjusting the machine.  To work your lats, do an exercise called the lat pulldown. Sit down on the weight bench and place your hands slightly wider than shoulder length apart. Slowly, pull the bar towards your chest, keeping your shoulder blades rolled behind you. Then, slowly return to the starting position. Strive for one set of 12 to 15 repetitions.  Start at a low level of weight and resistance on the machine and gradually work your way up each week. A resistance band is an elastic strap with handles on either end used in workouts that can be purchased at most sports or gym stores. You can also buy one online. There are a variety of exercises you can do using a resistance band that work the lats.  Try the bent over row. In this work out, you will stand on the center of the band with your feet spread slightly apart. Bend over slightly, with your knees somewhat bent, and grab both ends of the band. Form a 90 degree angle. Pull the band up towards your hips, squeezing your shoulders as you go, and then return to the original position. Do this for two to three sets of 10 to 12 reps.  You can also try a lying pullover. Anchor the band around a low lying immovable object, such as bedpost. Lie on your back, knees bent, and grab either end of the band with your arms held over your head. Then, pull the band in towards your torso and return to the original position. Do 8 to 10 repetitions.  The lat pulldown focuses more on the upper back. You will have to anchor the band around a high up object, such as a tree or a horizontal bar at your local gym. Kneel facing the anchor and grip either end of the band with your arms extended over your head. Bend your elbows to pull the band towards the floor. Contract your back muscles as you do this. Then slowly return to the starting position. Do two to three sets of 10 to 12 repetitions. You can also work your lats by incorporating chin ups into your workout routine. These can be done with a workout bar at your local gym.  Grab onto a pull up bar with your palms facing towards your torso. Keep your grip close to the width of your shoulders.  Keep your back straight and your lower back curved. Your chest should be sticking out slightly.  Pull yourself upward, breathing out, until your head is level with the pull up bar. Breathing in, lower your body back to the starting position.  If you are new to doing chin ups, it may take practice before you are able to successfully incorporate them into your workout. The number of repetitions depends on your overall fitness level. Start off by seeing how many chin ups you can do successfully before becoming tired and gradually build up from that number. To use dumbbells to work your lats, you will need to set a workout bench at a 30 degree angle. The weight of the dumbbells depends on your fitness level, but you should start at the lowest weight possible if you're new to working out.  Lie over the workout bench and grab one dumbbell in each hand. Keep your back straight and your shoulders back.  Bending your elbows, pull the dumbbells up towards your torso. Then, slowly return to the original position. Strive to do two to three sets of 10 to 12 reps.

Use a weight machine. Buy a resistance band. Do chin ups. Use dumbbells.
