Pull-ups is a great exercise for the upper body because it works the back, chest, shoulders,biceps and triceps all simultaneously. It’s the perfect strength training exercise that sculpts your body and adds amazing muscle definition, ideal for body sculpting. It can be a very difficult exercise to do because it uses your body weight and depending on how slowly you perform the exercise. It also will give you a great cardiovascular workout and for this reason pull-ups, included in a well-rounded fitness program, can help you lose weight - tone and lose those extra pounds.
I like to use a pull-up workstation that has multiple handles with multiple angles like the Hammer Strength workstation in my demonstration video below. If you like to work out in your home, Amazon offers pull-up exercise equipment that will suit your home gym or home workout needs too.
Doing this exercise in this manner works the muscles from many different angles and in many different ways and it provides you with a lot more exercise variation and motivation.
You can do them one after the other in a single workout (1,2,3,4) or separate into separate workouts (1 and 4 - 2 sets each); (2 and 3); (2 and 4), etc... A pull-up workout will then become more varied with many workout combinations.

If this is the first time trying pull-ups, I suggest that you use the assisted pull-up machine. It’s easier to do because you are not pulling up your entire body weight. By starting out slowly your muscles will get stronger. Once you are ready you can do this exercise unassisted using the regular pull-up bars and your entire weight. Start slowly. If you can only do 4 reps of 3 sets, that is fine. Do what you can do and feel comfortable doing. Over time, your muscles will get stronger, your stamina will improve and you will consequently be able to do more repetitions and sets.
