Pull ups have long been a staple exercise in gym routines due to their ability to work multiple muscle groups in one movement. Not only do they challenge the muscles in your upper body, but they also engage your core and lower back. If you want to build upper body strength and improve your overall fitness level, pull ups may be just what you need to add to your workout routine.
In this article, we’ll discuss what muscles are worked during pull ups and the various ways you can benefit from incorporating them into your training regimen.
Understanding Pull Ups: The Basics
Pull ups are a bodyweight exercise that involves lifting yourself up towards a bar or other overhead surface. Though the exercise may look simple, it requires significant strength and control to complete it successfully. Pull ups are excellent for both building upper body strength and increasing muscle mass.
What Are Pull Ups?

Pull ups are a type of exercise that target the muscles in your upper body, namely your back, biceps, and shoulders. They are performed by hanging from a bar with your palms facing away from you and pulling your body up towards the bar until your chin is above it.
Pull ups can be perofrmed with a variety of grip widths to target different muscle groups. The wider your grip, the more you’ll target your back muscles, while a narrower grip will emphasize your biceps and shoulders.
It’s important to maintain proper form when doing pull ups to avoid injury. Keep your core engaged, your shoulders down and back, and avoid swinging your body to gain momentum.
Different Types of Pull Ups
There are several variations of pull ups that can be performed to target different muscles. The most common types of pull ups are:
- Wide-grip pull ups: These are done with a grip that is wider than shoulder-width apart, and primarily target your back muscles.
- Narrow-grip pull ups: These are done with a grip that is closer than shoulder-width apart, and primarily target your biceps and shoulders.
- Chin ups: These are done with your palms facing towards you, and primarily target your biceps.
- Commando pull ups: These are done with one hand facing towards you and the other facing away, primarily targeting your biceps and forearms.
It’s important to switch up your grip and try different variations of pull ups to challenge your muscles and prevent boredom in your workout routine.
Incorporating pull ups into your workout routine can have numerous benefits, including increased upper body strength, improved posture, and increased muscle mass. Start with assisted pull ups or negative pull ups if you’re a beginner, and work your way up to doing full pull ups with proper form.
The Primary Muscles Worked by Pull Ups
The pull up is a classic exercise that targets a variety of muscle groups in the upper body. By using your own body weight as resistance, you can build strength and tone in your back, arms, and shoulders. In addition to the primary muscles listed below, pull ups also engage the forearms, core, and grip strength.
Latissimus Dorsi
The latissimus dorsi, or “lats,” are the largest muscles in the back and are responsible for pulling your body towards the bar during a pull up. These muscles are essential for developing a strong and defined back, and can also improve posture and reduce the risk of injury. To target your lats during a pull up, focus on pulling your elbows down and back towards your hips.
Biceps Brachii
The biceps brachii are the muscles located on the front of your upper arms. They help to bend your elbows and lift your body towards the bar during a pull up. While the biceps are not the primary movers in this exercise, they play an important role in assisting the lats and other muscles in completing the movement. To engage your biceps during a pull up, focus on keeping your elbows close to your body and pulling your chin over the bar.
Trapezius
The trapezius muscles are located in the upper back and neck and are responsible for stabilizing your shoulder blades during a pull up. They also aid in lifting your body towards the bar. Strong trapezius muscles can improve shoulder mobility and reduce the risk of injury. To target your traps during a pull up, focus on keeping your shoulder blades down and back, and avoid shrugging your shoulders towards your ears.
Rhomboids
The rhomboids are located in the middle of your back and are responsible for retracting your shoulder blades during a pull up. This helps to maintain proper posture and reduce the risk of injury. Weak rhomboids can lead to rounded shoulders and poor posture, so it’s important to engage these muscles during your pull up. To target your rhomboids, focus on squeezing your shoulder blades together as you pull your body towards the bar.
Deltoids
The deltoids, or shoulder muscles, assist the lats in lifting your body upwards during a pull up. They also help to stabilize the shoulder joint and maintain proper alignment throughout the exercise. Strong deltoids can improve shoulder mobility and reduce the risk of injury. To engage your deltoids during a pull up, focus on keeping your elbows close to your body and pulling your chin over the bar.
By incorporating pull ups into your workout routine, you can build strength and improve your overall fitness level. Whether you’re a beginner or an experienced athlete, there are many variations of the pull up that can challenge your muscles and help you achieve your fitness goals.
Secondary Muscles Engaged During Pull Ups

When it comes to pull ups, many people focus solely on the primary muscles being worked – the latissimus dorsi or “lats.” However, there are several other muscles that are engaged during this challenging exercise.
Forearms
The muscles in your forearms are responsible for maintaining your grip on the bar during a pull up. As you lift your body towards the bar, your forearm muscles are activated to keep your hands in place. This not only helps you to complete the exercise but also improves grip strength which can be beneficial in other areas of fitness, such as weightlifting or rock climbing.
Core Muscles
Pull ups require significant core strength to maintain proper form throughout the exercise. Your abdominals and obliques are engaged to stabilize your torso and prevent swinging or swaying during the movement. This means that not only are you working your upper body, but also your midsection, resulting in a full-body workout.
Lower Back
Your lower back muscles work to maintain proper spinal alignment during a pull up. They are essential for preventing injury and improving overall stability throughout the exercise. Weak lower back muscles can lead to poor posture and back pain, so incorporating pull ups into your workout routine can help to strengthen this area and improve overall spinal health.
It’s important to note that while pull ups are an excellent exercise for building upper body strength, they can also be challenging for beginners. If you’re starting out, consider using an assisted pull up machine or resistance bands to help you build up to a full pull up.
It’s also important to use proper form and avoid swinging or using momentum to complete the movement, as this can lead to injury.
Benefits of Incorporating Pull Ups into Your Workout Routine

If you’re looking to take your fitness to the next level, incorporating pull ups into your workout routine is a great place to start. Not only are they challenging exercises that can help you build strength and endurance, but they also offer a range of additional benefits that can improve your overall health and fitness. Here are just a few of the ways that pull ups can benefit you:
Improved Upper Body Strength
Pull ups are an excellent way to strengthen your upper body muscles, particularly your back, biceps, and shoulders. By engaging these muscles in a compound movement, you can difficultly build strength and endurance to replicate with other exercises. Over time, consistent training can lead to greater overall strength and endurance in these areas, allowing you to perform a wider range of exercises easily.
Enhanced Grip Strength
Since pull ups require you to hang from a bar or other overhead surfaces, they can help to improve grip strength over time. This can benefit other exercises requiring you to hold weight or equipment for extended periods, such as deadlifts, rows, and farmer’s carries.
By improving your grip strength, you can also reduce your risk of injury during these exercises, as you’ll be better able to maintain your grip on the weight or equipment.
Better Posture and Spinal Health
Pull ups require proper spinal alignment to perform correctly, making them an excellent exercise for improving posture and spinal health. By engaging your back muscles and pulling your shoulders down and back, you can help to counteract the effects of sitting at a desk or hunching over a computer all day.
Training your back muscles and strengthening your core can also help reduce the risk of lower back pain, a common issue for many people.
Increased Functional Fitness
Pull ups are functional exercise that mimics movements we make in our daily lives, such as pulling ourselves up to reach for an object. By improving your ability to perform this movement, you can increase your overall fitness and mobility, making it easier to perform everyday tasks.
Additionally, pull ups can be modified in various ways to make them more challenging, such as by adding weight or performing them on rings or other unstable surfaces.
Hopefully, we’ve answered “What muscles do pull ups work?” and other pressing questions about the exercise type. Pull ups are an effective and versatile exercise that can benefit anyone looking to improve their upper body strength and overall fitness level.
