Do chin-ups work the chest muscles? This is one of those unseen, but often asked questions I see from beginners. While setting out on your weight training journey, it’s important to know what exercises target which muscle groups. So, to answer that…
Chin-ups do not work your chest directly. Your chest acts as a stabilizing (or synergistic) muscle group during the chin-up, but it is not a primary or secondary mover. The primary and secondary muscle groups worked in the chin-up are the lats, rhomboids, rear deltoids, biceps, and forearms.
This article will cover the movement pattern of chin-ups, what muscles are worked, and how to hit the chest with other exercises.
What Muscles Do Chin-Ups Work?
The primary muscle group targeted by the chin-up are the lats (or Latissumus Dorsi). Any pulling movement, performed vertically (as with chin-ups) or horizontally (as with rows) work your lats to one extent or another.
Secondary muscle groups worked in the chin-up include: rhomboids, rear deltoids, biceps, and forearms. Depending on your grip style and width, the chin-up will target certain muscle groups more than others.
For example, the chin-up, as opposed to the pull-up, is performed with an underhand grip (AKA supinated grip). This supinated grip tends to work the lower lats and biceps more directly. To work the biceps even more, you would perform close grip chin-ups.
Why Don’t Chin-Ups Work the Chest?
Your chest muscles (pecs or Pectoralis Major) are NOT primary or secondary movers in the chin-up. Instead, the pecs act as stabilizing or synergistic muscles.
The chest supports the other muscle groups directly performing the exercise by remaining firm and stable. This is what it means to be a stabilizing muscle group.
The pecs also are not involved throughout the majority of the range of motion in a chin-up. Because of these reasons, it does not make any sense to say that chin-ups work the chest.
Now, if you have DOMS (Delayed Onset of Muscle Soreness) in your chest and you perform chin-ups, you will definitely feel it in your chest. But, again, that is due to the stabilization the muscle provides, not because it’s getting worked directly.
The Special Case of the Pullover
There is one exercise which is sort of up for debate about whether it works the chest directly or not. This is the pullover. Let’s focus on the dumbbell version of the pullover.
The dumbbell pullover is one of those rare exercises which doesn’t fall neatly into any specific category. It targets both your chest and your back. For some people, anecdotally speaking, it seems to target one or the other more or less.
For me, I definitely feel the dumbbell pullover more strongly in my chest. But, I’ve heard differently from many others. There are methods for placing the emphasis more on the chest or back.
The movement itself is a combination of both pulling the dumbbell overhead (with your lats) and pushing the dumbbell overhead (with your pecs). Developing a strong mind-muscle connection will allow you to laser in on your muscles and feel these working in the pullover.
What Exercises Work Chest?
The truth is, you don’t need chin-ups for excellent chest development. The chin-up is a fantastic back exercise, and there are plenty of great chest exercises to perform in its place:
Barbell or Dumbbell Bench Press
By far, the best exercise for putting slabs of muscle onto your pecs is either the barbell or dumbbell bench press. I mean, most people are introduced to the world of weight training through the old fashioned bench press.
In general, I advise people to choose the dumbbell bench press instead of the standard barbell bench press for a few reasons:
- Dumbbells are generally safer on your shoulders
- It’s easier to feel your pecs working with dumbbells
- Less chance of a freak accident (like the barbell slipping and falling on your neck or you getting pinned under it. ALWAYS use a spotter when performing the barbell bench press)
Bench presses have a lot of variations to them, as you can also perform the incline bench press (which targets the upper chest more) or the decline bench press (which puts even more emphasis on the chest).
Watch this video from Anabolic Aliens on how to properly perform the flat dumbbell bench press:
Dumbbell Fly
The dumbbell fly is the other classic chest builder. These used to be a lot more popular back in the golden age of bodybuilding. They’ve come under heavy criticism because of the compromised position your shoulders are put in when performing them.
You can also perform these in the flat, incline, or decline positions. To understand how to perform flys safely and effectively, take a look at this video from Mind Pump TV:
Cable Crossover
The cable crossover is another popular chest exercise, although this one pretty much requires a gym membership (unless you have a killer cable machine at home, in which case I’m jealous!).
The crossover is pretty simple and harmless to perform. You can also set the pins from low to high, similar with the decline and incline angles available for chest presses and flies.
To get a good idea of how to perform the movement effectively, watch this video from Jim Stoppani, PhD:
If you don’t have access to a cable machine, you can also perform these with bands, as FlexWell demonstrates here:
Push-Up
It doesn’t get anymore basic than, “Get on the floor and give me ten!”. The basic push-up is still an excellent chest exercise, even in 2021! It’s hard to progress with weight on it, although you can wear a weighted vest or have someone place a weight on your back.
I recommend simply using push-ups as a “burnout” exercise for your chest. Perform your other chest exercises first and then perform push-ups last, to fully fatigue your pecs.

Wrap-Up
Although you might be able to feel your chest muscles stabilizing your body during the chin-up, we can clearly see now it doesn’t make sense to say chin-ups work the chest.
Plus, now you have some good, basic chest exercises to get you off on the right foot.
Time to get after it!
