A pull up bar is a simple piece of equipment that can be attached to the doorway of your house for pulling exercises. Any sturdy tree branch, existing railings by the stairs or basically any horizontal bar on which you can hang from can also be improvised pull up bars.
Pull ups are basically upper body exercises performed with the body suspended, arms extended with palms doing an overhand grip on the fixed bar. Pull ups differ from chin ups in that the latter uses an underhand grip. Pull ups workout the lats while chin ups target the biceps more specifically. Pull ups are also easier to do. Both exercises, however, are essential in building muscle, developing grappling or gripping strength and in promoting overall shoulder health and balance.
The most basic pull up exercise is done by hanging from the pull up bar before pulling the body directly upwards without kicking or swinging and using only the power from your upper body. As a beginner, it will be difficult to do even a single correct pull up. As you get begin to develop and strengthen the muscles in your upper back and get more used to this kind of exercise, you should be able to do at least six pull ups. This is the minimum number of pull ups you can do to gain any benefit from it.
