First you'll need to find a pullup bar. If you don't have a gym, try a heavy tree branch or playground equipment. If you're light and have a sturdy door you can use the top of the half-open door (put a towel over it first). Be certain that whatever you use can support your weight and won't cause any damage before you try the exercise. Make sure you can at least hang from the bar before attempting a pullup.
There are several grips you can use. Your workout will specify which grip to use. For the outside grip, hold your hands so your palms are out and grasp the bar. Your thumbs should not wrap under, but they should be next to your index fingers. Your hands should be about shoulder width apart unless the workout specifies a closer or wider grip. For the inside grip, turn your palms toward you and grab the bar.
Pull yourself up by squeezing your shoulder blades together and driving your elbows to your back. Lean backward slightly to focus the workout on your upper back and not your arms. If you cannot get your chin to the top of the bar, you should try assisted pullups in a gym, or find a low bar where you can keep your feet on the ground.
