How to Do a Strict Pull-up: Muscles Worked, Form and the Reps People Fake
The pull-up is the cheapest lat-width builder there is, and the one most people shorten at both ends: no dead hang at the bottom, no chest at the top.

What is the Pull-up?
The pull-up is a vertical pulling exercise performed hanging from an overhead bar with an overhand grip just outside shoulder width, pulling your chest to the bar and lowering back to a full dead hang. It trains the latissimus dorsi and teres major hardest, building the width that reads as a V-taper, and it needs nothing but a bar.
The one cue that matters: Start from a dead hang and lead with your chest to the bar, not your chin.
Why the Pull-up is worth doing
- Loads the lat across its longest range, from full overhead reach at the bottom to fully shortened when your chest meets the bar
- Sets the strength standard every other bar exercise is measured against: strict reps from a dead hang, no swing
- Costs nothing and travels, since a doorway bar or any playground bar runs the whole session
- Scales in both directions without changing the movement, with bands and negatives below bodyweight and a dipping belt above it
How to do the Pull-up
- Set your grip Take an overhand grip just outside shoulder width, thumbs wrapped or hooked over the bar, and hang with the arms straight. The hands should sit far enough apart that your forearms are close to vertical at the top rather than angled inward.
- Hang, then depress Begin in a full dead hang with your shoulders up by your ears, then set the blades down your back before a single elbow bends. That first inch belongs to the rep, and skipping it is where a swing gets born.
- Pull chest to bar Drive the elbows down toward your ribs and lead with the sternum, not the chin. Keep the ribs down and the legs together so the whole body moves as one rigid line.
- Own the top Finish with the bar level with your upper chest and the elbows under your shoulders, then hold for a beat. If your chin is craning over the bar, you are an inch short of the rep.
- Lower under control Take two seconds down and let the blades travel back up at the very end so the next rep restarts from a true hang. Cutting the last few inches turns a set of eight into a set of eight halves.
- End the set clean Stop on the last rep you can begin from a dead hang without a kick or a swing. Drop off the bar rather than grinding a rep whose bottom half you cannot control.
Muscles worked
The Lats (latissimus dorsi) do the bulk of the work. From a dead hang the lat sits at full length, running from the upper arm down to the lower spine and pelvis, and the pull-up asks it to shorten across that entire span as the elbow travels from overhead to your ribs. Almost nothing else loads it from quite that far away.
Teres Major (teres major) works on a much shorter lever. It spans the shoulder blade to the upper arm and nothing else, so it hauls the elbow in toward your ribs without the long reach down to the pelvis that the lat has. It sits right at the armpit, which makes it the muscle deciding how wide the top of your V reads from behind.
The overhand grip also asks the Lower Traps (trapezius, mid and lower) to hold the shoulder blades down for the whole pull. That is why the pull-up carries Upper Back as a secondary zone even though nothing about it looks like a row.

Form tips
- Grip width sets the path. Go wider than about one and a half shoulder widths and the elbows run out of room before the chest reaches the bar. Just outside the shoulders keeps the forearms vertical at the top, where the lat is doing the most.
- Thumb over the bar. Hooking the thumb on the same side as the fingers lets the hand sit a little behind the bar and takes some of the forearm out of the equation. Worth trying if your grip quits before your back does.
- The legs are part of the rep. Cross your ankles and squeeze them together, or hold the legs slightly in front. A loose lower half becomes a pendulum, and every swing you damp out costs you a rep.
- Eyes on the bar. Look at the bar rather than the ceiling. Tipping the head back is how a chin-over-bar rep gets counted while the chest is still four inches away.
Common mistakes
- Kipping for one more
- A hip snap moves your bodyweight with your legs, so the last two reps of the set teach the back almost nothing. Cut the set at the last strict rep and add the extra work as an assisted set or a slow negative.
- Half-hanging at the bottom
- Stopping with the elbows bent keeps tension on the lats but skips the range they grow from and inflates the rep count. Straighten the arms completely and let the shoulders rise before the next pull.
- Chin over, chest nowhere
- Craning the neck clears the bar without finishing the shoulder work, so the top of every rep is missing. Aim your collarbones at the bar and accept the smaller number.
- Elbows drifting behind the ears
- When the elbows travel wide and back, the arms end up pulling across a short range and the lat never fully shortens. Drive them straight down toward the sides of your ribs.
Sets, reps and where it fits
Nothing goes ahead of the pull-up on a back day — not rows, and not anything that pre-tires your grip. The plan BackMaxx builds asks for 3 sets of 6–10 reps, which is the range where strict reps stay strict; if you are getting twelve clean ones, add load rather than reps. Two to three minutes between sets, because this is strength-shaped work even when it looks like conditioning.
Progress by adding one rep to one set each week until every set hits the top of the range, then start over lower with a belt or a vest. If your sets drop below about five, spend a block on negatives and assisted reps — the Pull-Up Progression runs exactly that ladder across six weeks. On a full back day, two or three hard sets here plus horizontal rowing covers both Lat Width and Upper Back.
Variations and similar exercises
- Chin-up
- Turning the palms toward you shortens the lever at the elbow and hands a bigger share to the arms, so the same effort usually buys a few more reps — the pick when overhand sets stall at four.
- Negative Pull-up
- The lowering half only, taken slowly from the top, which is the right call when you cannot yet start a rep from a dead hang.
- Weighted Pull-up
- The same movement with a belt and plates, for when ten strict reps stop being hard and you want the pattern back in a low rep range.
- Wide-Grip Lat Pulldown
- The cable version, where the machine carries your bodyweight, so the volume you can do is not capped by your grip or by your current rep count.

What the research says
The overhand grip is what separates the pull-up from the chin-up, and it has been measured directly.
- In 25 young adults tested on both, the pull-up drew significantly more lower-trapezius activity than the chin-up, while the chin-up drew more from the biceps and chest. That fits the pull-up’s reputation as the version that makes the shoulder blades work. [1]

Frequently asked questions
How many pull-ups should I be able to do?
There is no universal number, but only strict reps from a dead hang are worth counting. Three sets of 6–10 is what BackMaxx programs, and hitting the top of that range on every set is the point where adding weight makes more sense than adding reps. Below five per set, negatives and assisted work build the strength faster than grinding partials.
Do pull-ups build lat width or back thickness?
Width, mostly. The pull-up loads the lats with the arm overhead and drives the elbow down toward the ribs, which shortens the lat along its length and fills out the flare below the armpit. Thickness between the shoulder blades comes from horizontal pulling, so a back day needs both — the Upper Back exercises cover the other half.
Are pull-ups better than lat pulldowns?
For the same number of hard sets they train the same muscles, and the pull-up wins on the parts a machine cannot copy: you stabilize your whole body from the floor up, and the resistance is exactly your bodyweight, no more and no less. The pulldown wins on precision, since you can pick a weight above or below what you can hang from a bar, which matters when you want twelve controlled reps instead of six ugly ones.
Should I use chalk or straps for pull-ups?
Chalk, if your hands slide. Straps only if your forearms consistently quit before your lats do, which mostly happens on high-rep sets and on thick bars. A thumb-over grip buys some of the same time for free. The more durable fix is separate hanging work — the dead hang adds hang time without adding pulling fatigue.
Should the Pull-up be in your plan?
BackMaxx scores your lat width from one photo and builds the week around whatever is lagging — so the Pull-up only shows up when it is the right call.
