Chin-ups, just as most exercises use a primary & secondary muscle group. The primary muscle group would be the back (or latissimus dorsi). This is what helps to give that "V" - shape in the torso area. (along with slimming down the torso area, of course) The secondary muscle group would be the biceps. Depending on your grip position, you can focus either more on your "lats", or arms.

The primary muscle groups targeted during pull-up exercises are the latissimus dorsi (back muscles), biceps, and forearms.

To effectively perform a modified pull-up to target specific muscle groups, focus on using a narrow grip to engage the biceps and upper back muscles. Keep your elbows close to your body and pull yourself up towards the bar, focusing on squeezing your shoulder blades together at the top of the movement. This will help target the desired muscle groups effectively.

The traditional pull up is a so-called `compound` exercise, which means it targets most of the muscle groups of the upper body (so basically it trains your entire upper body fairly equally). In my experience though, the muscles which grew tired the most after every pull up workout and in long-term grew the most were the obliques and shoulder muscles.
To effectively target your lats with pull-up exercises, focus on engaging your lats by pulling your shoulder blades down and back as you pull yourself up. Ensure proper form, such as a wide grip and full range of motion, to maximize lat muscle activation.
A squat pull-up rack is a versatile piece of equipment that can help improve strength in various muscle groups. It allows for exercises like squats, pull-ups, and other bodyweight exercises, which can target multiple muscle groups simultaneously. This can lead to increased muscle mass, improved overall strength, and enhanced functional fitness.
A pull up bar is used as a piece of equipment to build the upper body without the use of free-weights. Most people who use a pull up bar are attempting to increase upper body strength and muscle mass. A pull up bar is used to target the arms, chest, and core.
Some effective exercises that can be done with a low pull-up bar include chin-ups, hanging leg raises, and inverted rows. These exercises target different muscle groups and can help improve strength and muscle tone.
