Pull-Up Form: Strict vs. Kipping, and What Chin Over the Bar Really Means
Ask five people at a gym how many pull-ups they can do and you will get five numbers that do not mean the same thing. One person means dead hang to chin over the bar. Another means chin to the bar with a bit of swing. A third is counting the ones where the eyes got there. The number is only useful if everyone agrees on what a rep is.
This post is about that agreement. What a strict pull-up is, how to set up and pull, where kipping fits and where it does not, and why the chin clearing the bar is the line that decides whether a rep happened.
What a strict pull-up is
A strict pull-up starts from a dead hang: arms straight, feet off the floor, body still. You pull until your chin is above the bar, then lower under control until your arms are straight again. That is one rep. No swing, no kick, no bounce out of the bottom.
Grip changes the name, not the standard. Palms facing away is a pull-up. Palms facing you is a chin-up, which most people find a little easier because the biceps contribute more. A neutral grip on parallel handles sits between the two. All three are strict if the hang is dead and the chin clears the bar.
The reason to care about the strict version, even if you never plan to compete in anything, is that it is the version that builds strength. Every shortcut in a pull-up removes work from the muscles you are trying to train.
Setting up: grip, hands, and the hang
Most form problems are decided before the pull starts. Take a few seconds at the bottom to get these right.
| Element | Do this | Not this |
|---|---|---|
| Grip width | A little wider than shoulders | Very wide (shorter range, harder on the shoulders) or hands touching |
| Thumb | Wrapped around or resting on top, whichever you keep every rep | Switching between sets |
| Wrist | Straight, knuckles pointing up | Bent back so you hang from the fingers |
| Shoulders at the bottom | Let the arms straighten, then pull the shoulder blades down slightly | Shrugged up into the ears |
| Legs | Together, straight or crossed at the ankles, slightly in front | Swinging or cycling |
| Eyes | Straight ahead or slightly up | Craning the head back to look at the bar |
The bottom position is where swing starts. If your legs are moving in the hang, they will still be moving at the top. Squeeze your glutes, tuck your ribs a touch, and let the swing die before you pull.
The pull and the lowering
Start the rep with the shoulder blades, not the elbows. Pull them down and slightly together before your arms bend. It is a small movement, an inch or so, but it puts the lats in charge instead of the arms, and it is what stops the shrug at the top.
Then drive the elbows down toward your ribs. Think of pulling the bar to your upper chest rather than pulling your chin up to it. When the elbows come down and back, the chin clears the bar on its own, without the head reaching forward for it.
Lower with control. One to two seconds, all the way to straight arms. Dropping through the bottom saves effort, but it throws away the eccentric half of the rep, which is where a lot of the strength comes from, and it is rough on the elbows over time. The bottom of the rep is the beginning of the next one, so arrive there still and ready.
Strict vs. kipping: an honest comparison
Kipping is the swinging pull-up from CrossFit. You drive with the hips, use the momentum to get over the bar, and cycle reps far faster than a strict pull-up allows. It is a real skill. In a timed workout where a hundred pull-ups appear next to rowing and burpees, kipping is the correct tool and nobody is cheating by using it.
It is also training something different. Kipping trains cycling speed and conditioning. It does not build pulling strength at anything like the rate strict reps do, because momentum is doing the part of the movement that would otherwise build it. The usual advice, and it is good advice, is to own several strict pull-ups before you learn to kip. The shoulder takes a lot of load at the bottom of a kip, and a shoulder that cannot do a strict rep is not ready for it.
| Strict | Kipping | |
|---|---|---|
| Momentum | None | Hip drive and swing |
| What it trains | Pulling strength | Cycling speed, conditioning |
| Reps per set | Fewer | Many more |
| Best used for | Getting stronger, testing a max | Timed workouts, high-rep sets |
| Recommended prerequisite | None | Several clean strict reps |
| Counts under most strength standards | Yes | No |
The problem is not kipping. It is kipping by accident. A beginner who swings to get the last rep is not doing a CrossFit skill. They are skipping the top of a strict rep and calling it done.
Chin over the bar: why the line is where it is
Every serious pull-up standard, from military fitness tests to gym bragging rights, puts the rep at the chin. Not the eyes, not the nose, not "close enough." There is a good reason. The last few inches, where your elbows are most bent and the lats have the least leverage, are the hardest part of the movement. A rep that stops short skips the hardest part, so counting it means counting the part you did not train.
It is also the easiest place to fool yourself. From inside the rep you cannot see where your chin is. It feels high. Film a set from the side and most people find that a few of their reps stopped an inch short.
This is why PULL UP KING counts the way it does. The camera fixes a line at the bar and moves the number only when the chin clears it. A kip that swings up and stalls under the line is not a rep, and neither is a strict pull that stops at the nose. It is the same rule a strict judge would use, applied to every rep instead of the ones you remembered to check.
| Fault | What it looks like | Fix |
|---|---|---|
| Half rep | Eyes or nose reach the bar, chin does not | Pull the bar to the chest; count only chin-over reps |
| Reaching with the chin | Head pokes forward to sneak over | Keep the head neutral; the chin follows the chest |
| Swinging | Legs pendulum on every rep | Glutes tight, ribs down, let the hang settle before each pull |
| Shrugging | Shoulders end up next to the ears | Pull the shoulder blades down first, before the elbows bend |
| Flared elbows | Elbows point out to the sides at the top | Drive elbows down and back toward the ribs |
| No lockout | Arms never straighten at the bottom | Finish each rep at a dead hang, even if it costs a rep |
| Dropping | Falling through the lowering | Two seconds down; the lowering is half the rep |
Fix one of these at a time. Most of them are connected, and shrugging, flaring, and half reps tend to disappear together once the pull starts from the shoulder blades and finishes at the chest.
Let the camera judge the rep
PULL UP KING counts a pull-up only when your chin clears the bar line. No half reps, no kipping.
