It actually builds everthing in your upper body. Shoulders, back, pecs and it also developes your grip.
Pullups primarily target the muscles in the back, specifically the latissimus dorsi, which are responsible for pulling the body up towards the bar.
Yes, pullups are an effective exercise for building biceps because they engage the bicep muscles as you pull your body weight up.
The two best exercises are deadlifts (mostly for traps) and pullups. It's also important to do pulling exercises such as different types of rows for your lats. If you aren't strong enough to do pulups, there are different types of machines that can provide assistance.
To improve your strength and technique in modified pullups, focus on gradually increasing the number of repetitions you can do, maintaining proper form throughout each movement, and incorporating variations of the exercise to target different muscle groups. Additionally, consider incorporating resistance training exercises that target the muscles used in pullups, such as rows and lat pulldowns, to further enhance your strength and technique.
It will come slowly as you build muscle on the rest of your body. It will come slowly as you build muscle on the rest of your body.

It takes quite a while to build muscle from walking, but it takes only a short time to build good strong leg muscle from jogging or running.
Compound movements like pullups/chinups, and barbell rows will develop biceps proportionally with your other muscle groups. Isolation movements that focus on the bicep include all types of curls, concentration curls, preacher curls, hammer curls all help build your bulging biceps.
It is not exactly necessary, but if your goal is to build muscle, weight training is the best and "quickest" way to do so. On the other hand, you can build muscle with just calisthenics. Instead of banging out those pushups as fast as you can to get the most reps, lower the repetition count with slow, controlled movements, which really does build muscle. When even those become easy, try different variations, such as archer pushups, one-handed pushups, and so on. Same with pullups. For legs, though, hill sprints work legs quite fine, but adding weight seems almost necessary to build serious muscle. Other factors are involved as well. Sleeping well and having a sufficient calorie intake are both important aspects. The right supplementation can help as well. You might want to check the link in my bio to learn more.
Standing on one leg can help improve balance and stability, but it is not a primary way to build muscle. To build muscle, it is more effective to do exercises that target specific muscle groups with resistance training.
The three symptoms of lactic acid build-up are muscle fatigue, muscle soreness, and muscle weakness.
Eat protein: chicken, steak,and fish. and do kruches,situps,bicycles, pushups, and pullups.
