" If you would rather use less equipment, or want to incorporate at home workouts into your normal routine, there are a variety of lats workouts you can do without equipment. Two of the easiest kind are the "reverse snow angel" and the "dolphin kick."  For the "reverse snow angel," lie face down with your arms and legs at your sides. Your palms should be facing down. Move your hands and shoulders a few inches off the ground and move your arms up to your shoulders until your thumbs meet. Then, return to the original position. Keep your arms straight and elbows locked throughout the entire movement. Strive for two to three sets of five repetitions, resting for about 30 seconds between sets.  To do the dolphin kick, you will need a workout bench. Position yourself face down on the bench, with your hips at the end of the bench. Your hands should grasp the underside of the bench for support. Pointing your toes away from your body and keeping your hips straight, point your legs upward and then hold the position for 5 seconds. Slowly return to the original position and then repeat. Aim for two to three sets of six to 12 repetitions, with 30 second breaks in between. The superman is a great activity for your lats. To start, you'll need to lie face down with your chin facing the ground, your ankles touching, your arms spread forward, and your toes pointed outward.  By contracting your back and shoulder muscles, pull your arms and legs a few inches off the ground. Try to get your hand and feet elevated around the same height. Try to hold this position for 15 to 30 seconds.  Do six to 15 repetitions of this exercise, with 30 to 60 seconds of rest in between. There are some exercises you can do to work your lats that involve standing up. The hip hinge means standing up straight, with your hands on your hips, and your feet spread apart slightly wider than your hips.  Bend forward slowly, while keeping your shoulders and hips aligned. Bend until you are parallel to the floor and your body has formed a 90 degree angle.  Bring yourself back to the starting position and then repeat. Do three sets of 10 to 15 repetitions with 30 second breaks in between.
