Key points:

  1. Drive the bar back toward your face as you press the bar off your chest instead of initiating the press by driving the bar straight up.  This makes the lift MUCH more efficient.
  2. Most people can lift more weight pretty quickly simply by correcting their bench press bar path, and at the elite levels, adopting a more efficient bar path is the primary way lifters keep improving their numbers.
  3. That’s about it.  The rest of the article is mainly graphs and pictures to illustrate this point in case it doesn’t click for you right away.

Let’s take a trip back in time to 1984.

1984 was a great year, for three primary reasons

  1. Van Halen put out their best album (some people argue for 5150.  They are wrong).
  2. Apple launched the Macintosh computer.
  3. Thomas McLaughlin published Bench Press More Now:  Breakthroughs in Biomechanics and Training Methods.

To this day, McLaughlin’s book is probably the best resource for the bench press in existence.  It’s not without its faults or omissions (it doesn’t even touch on leg drive, for example), and it’s probably a hair too technical for some readers, but I haven’t come across another resource that approaches its combined level of technical analysis and applicability.

It’s a shame that more lifters don’t know of the work that came out of McLaughlin’s lab at Auburn.  From the late ’70s through the ’80s, they published a lot of very good, very applicable studies on powerlifting.  McLaughlin and several of his research partners were nationally ranked powerlifters, and they gathered a lot of their data from the best source imaginable if you want to understand elite powerlifting performance:  high-level powerlifting meets.  In several of their studies, they wouldn’t include a lifter’s data unless the lifter was ranked in the top 10 in his weight class. In one particularly amusing example from a squat study, their “low skill” group included lifters who squatted 620 at 242 and 550 at 193 (their “high skill” group included only national champions).

At its core, the book is based on several studies that compared the bench press technique of world-class benchers to the bench press technique of “novice” benchers (their novices still benched 224 at 170, on average, and would be considered “well-trained” by the standards of a lot of studies) with maximal loads.  Any old-looking picture in this article comes McLaughlin’s books, which you can read spread across 16 parts on everyone’s favorite old-time strength blog (part 1 is here).

It has a lot of interesting insights, but there’s just one that I want to focus on in this article:  bench press bar path.

He found that both the novice benchers and the elite benchers lowered the bar using a similar pattern:  roughly a straight line, arcing out slightly.  However, their bar paths during the press itself differed drastically.  The novice lifters pressed almost straight up initially, with the bar then moving up and back more toward the top half of the lift.  The elite lifters followed the opposite pattern – they initially pressed the bar up and back at the start of the lift, and finished the lift by pressing the bar almost straight up toward the top half of the lift.

Bench Press Bar Path
The picture on the left shows the bench press bar path of a novice benching 245lbs. In the middle is Mike Bridges benching 463lbs. On the right is Kaz benching 605lbs.

When he looked at elite lifters who’d improved their performance over time (since he collected data at all the major meets over a 4-year period), and compared them to elite lifters whose performance had stalled, he saw the same trend.  Elite lifters who hadn’t improved their bench numbers used roughly the same bar path every year, while elite lifters whose bench numbers continued to rise pushed the bar back toward their face to start the press more and more as their lifts improved.

Why is this?

The simplest explanation:  This technique decreases total flexion demands at the shoulder with any given grip width.

To complete a bench press, you have to perform three basic movements: shoulder flexion (like a front delt raise), shoulder horizontal flexion (like a pec fly), and elbow extension.

This article isn’t going to address elbow extension demands (how hard a lift is for your triceps) because this article seeks to isolate the effects of bar path, which doesn’t affect elbow extension demands too terribly much; elbow extension demands are primarily a function of grip width and whether your elbows stay under the bar or not.

So we’re left with two functions that are impacted by bar path:  shoulder flexion, and shoulder horizontal flexion.

Luckily, we can simplify things even further, because differentiating between the two doesn’t matter all that much for our purposes here.  The main muscles carrying out both roles are your pecs and your front delts.  Both of them can flex the shoulder, and both of them can horizontally flex the shoulder.  The front delts are a bit better at flexion, and the pecs are a bit better at horizontal flexion, but they both contribute, regardless of the mix of flexion and horizontal flexion demands.  So, rather than separate out flexion and horizontal flexion demands, I’ll just lump both of them together and refer to the sum of flexion and horizontal flexion demands as “total flexion demands.”

So, what determines total flexion demands?

As with anything else:  joint moments.  Load x moment arm.

If you shorten the moment arm, total flexion demands decrease, so you can lift a greater load, or you can lift a given load with more ease.  So, what determines the length of the moment arm?

Imagine a plane passing through your shoulder joint that’s parallel to the floor.  Since the barbell’s force is pressing straight down into your hand, draw a line straight down from your hand to the plane.  Then draw a straight line between that intersection point and your shoulder.  That’s your moment arm.


Don’t worry!  That sounds convoluted, but it’s actually pretty simple.  There are two things that change the length of that moment arm:

  1. Grip width
  2. The distance from the bar to your shoulder in the frontal plane (if you’re looking at it from the side, then this would be the horizontal distance between the bar and your shoulder).

A wider grip increases the length of this moment arm, as does increased distance from the bar to your shoulder in the frontal plane.  Grip width determines the horizontal flexion aspect of total flexion demands, and frontal-plane distance from the bar to the shoulder determines the flexion aspect of total flexion demands.

So, assuming any given grip width and any given load, the only thing that really impacts total shoulder flexion demands is the position of the bar in relation to the shoulder.  Total flexion demands at the shoulder decrease the closer the bar is to being directly over the shoulder, and total flexion demands at the shoulder increase the further the bar is from the shoulder in the frontal plane.

Bar positioning moment arm
Grip width doesn’t change (dark blue), but as the bar gets further in front of the shoulder (light blue), the moment arm (black) gets longer and longer, meaning the lift gets harder and harder.

I think we all realize this when we’re holding the bar at lockout.  It’s a lot easier to hold the bar directly over your shoulders than it is to hold the bar over your sternum or your upper stomach, for example.  The exact same principle applies at every other point in the lift.

Of course, if you wanted to take this principle to its logical extreme, you’d assume that the guillotine press must inherently be the most efficient way to bench press.  Keep the bar directly over your shoulders the whole time, and you’re golden, right?

Touching the bar lower on your chest obviously shortens the range of motion, assuming you get a decent arch.  Not only does this decrease the effort required to complete each rep with a given load, it also keeps you from having to go through extreme ranges of motion that will inherently be weaker.  Regardless of external moments, maximal internal moments – the moments your muscles produce at each joint to move your limbs and extend the bar – drop off rapidly as range of motion increases past a certain point.

Touching low can be overdone too, of course.  If you touch too low, total flexion demands continue increasing, negating any advantage you may have gotten by limiting range of motion.  As with most things, there’s a happy middle.  Anywhere from just below the nipples to about an inch below the xiphoid process of your sternum works best for most people.

Assuming you touch the bar (reasonably) low on your chest/high on your stomach, the next challenge is to actually press the weight back up.

This is where McLaughlin’s research comes into play.

The novice lifters initiated the press by shoving the bar essentially straight up off their chest, with the bar path angled back only slightly.  Since the bar didn’t move back toward their shoulders very much, total flexion demands at the shoulders were still very high (relative to the load they were lifting) when the bar reached the sticking point of the lift a few inches off the chest.

The elite lifters, on the other hand, initiated the press by shoving the bar up off their chests and back toward their shoulders.  Since the bar did move back toward their shoulders, total flexion demands at the shoulders decreased as the bar approached the sticking point.

Bar path 2
Average bench press bar paths for novice lifters (dashed line) vs. elite lifters (solid line).  Especially pay attention to the short segment between points 4 and 6 on each line.

Compare the sticking points (the point where the lifters were applying the smallest amount of force to the bar) of the novice lifters to those of the elite lifters:

Sticking point novice elite

One thing worth noting about this picture:  The “heavy experts” dot is a bit further from the shoulder than it “should” be if this was scaled for body size.  The novices and the light experts were roughly the same height and had torsos roughly the same length, but the heavy experts were taller and had longer torsos, so 5 inches in front of their shoulders would be closer to ~4 inches in front of the shoulders of the other two groups, so for an even more accurate representation, that dot should be moved back toward the head a bit.

Regardless, both groups of experts had much less horizontal distance between the bar and their shoulders than did the novice group.  This helps minimize the total shoulder flexion demands, increasing how much force they could apply to the bar.

So, how large of a payoff can you expect from that technique change?

A pretty big one.

Force output at different points in the movement for novice and elite lifters.
Force output at different points in the movement for novice and elite lifters.

McLaughlin found that the elite benchers could bench about 10-12% less than the maximum force observed in the movement, and about 4-5% more than the minimum force observed in the movement.  The novices, on the other hand, could bench about 35% less than the the maximum force observed in the movement, and about 7-8% more than the minimum force observed in the movement.

Max and Min Bench Press force Novice vs. Elite

Remember, you don’t miss a lift because you are too weak through the full range of motion.  You miss a lift because you were too weak through the very weakest part of the lift.  For all three groups, their bench maxes were slightly above their minimum force output, which is what you’d expect.  It doesn’t matter if you have “extra” maximum force at some stronger point in the lift – your minimum force at the weakest point in the lift is what will stop you from completing a rep.

In both groups of elite lifters, their minimum force output was only about 13-14% lower than their maximum force output, indicating a very smooth and efficient lift, whereas for the novice lifters, their minimum force output was about 32-33% lower than their maximum force output, indicating a very inefficient lift.

That inefficiency primarily came from their bar path.  Their force production dropped off so rapidly because when they reached the position of minimum force – the sticking point – they were in a horrible position to exert force on the bar because the total flexion demands at the shoulder were unnecessarily high.

If we took a myopic view of this information, we’d assume that simply changing the bar path would instantly increase their bench press from 224 to about 270 (about 10-12% less than their maximum force output, bringing them in line with the elite lifters) instantly.

Obviously that never happens in the real world…at least not instantaneously.

As previously mentioned, one thing that McLaughlin noted in his research was that the elite lifters’ maximum force output didn’t change much from year to year, but some continued adding weight to their bench press, while some plateaued.

The ones who kept benching more and more in spite of minimal changes in maximum force output were the ones who altered their technique over time, pushing the bar back toward their shoulders further and sooner.  The people who didn’t keep adding weight to their bench press were the ones who didn’t make this technique adjustment.

Here’s the type of change this adjustment can make:

Mike Bridges Bench Improvement

Mike Bridges added 60lbs to his bench in a year (386 to 446) by altering his bar path to dramatically increase the minimum force he could exert on the bar.  Force = mass x acceleration, and the minimum acceleration (labeled “7” on both graphs, coinciding with minimum force) increased dramatically between 1978 and 1979, allowing him to bench more even as maximum acceleration decreased (maximum force still increased a bit though, because there was more weight on the bar).  This is the hallmark of more efficient technique:  minimum force during the movement approaching maximum force.

However, it’s worth reiterating that it took Bridges an entire year to transform his technique and take his elite-level bench to world-record levels.  There are two main reasons altering your bar path won’t increase your bench by nearly that much instantly:

  1. It’ll take some practice for the new bar path to feel natural, and for you to build skill and automaticity with a slightly altered motor pattern.
  2. Your current technique may be hiding weaknesses – specifically muscles that are currently weak through a particular range of motion.

However, neither of those things take too long to address, at least on the time scale of an entire training career.  These are both areas where you can see meaningful progress in a matter of weeks or months, not a matter of years (unlike the glacial pace of hypertrophy at the elite levels).

Motor learning is a (relatively) fast process, and developing strength through this slightly different range of motion shouldn’t take too long, because the changes in joint angles and muscular demands aren’t particularly big.

This bench press bar path makes the midrange of the lift a lot easier on the anterior deltoids, but slightly harder on the pecs.  Splitting the total flexion demands apart again, shoulder flexion demands are way lower (which is why it’s easier on the anterior deltoids) and horizontal flexion demands are unchanged.  However, when you reposition the bar over the shoulders, the anterior deltoids can’t help out quite as much anymore, so the movement gets a little more challenging for your pecs.

Simply correcting your bar path and benching with this technique should naturally strengthen the pecs more.

Here’s how it looks in practice:

Bench press bar path
Top: good. Bottom: bad.

One final question I’m sure someone will ask:  Isn’t the easiest path between two points a straight line?

In this case, no.  Remember, gravity is pulling the bar straight down.  Total work done on the bar is simply defined by the vertical distance you have to move it, not total distance.  If you’re touching the bar to the same place on your chest/stomach, you’re using the same grip width, and your arms aren’t magically getting longer or shorter, total work done on the bar is identical regardless of bar path.

This is a question about how to do that work the most efficiently.

Bar Path Work

Total work done on the bar is the same regardless of bench press bar path, but driving back and then up is simply the most efficient way to go about producing that work.

So, to wrap things up, here’s what you should do:

  1. Take video of your bench press from the side.
  2. Use an app like Iron Path to see your bar path.
  3. If your bar path resembles the elite lifters in McLaughlin’s studies, great!
  4. Otherwise, work on purposefully driving the bar back toward your shoulders as you press it off your chest.  Consistently take video to observe the changes.  It may feel a little weird at first, but you’ll get the hang of it in no time.
  5. Keep grinding away at it, and you should start hitting PRs within a couple of months (likely sooner).

One final technical note:  some very savvy readers may notice that I disregarded horizontal forces on the bar in my analysis.  However, in this case, they don’t change the overall picture because they would be the same regardless of bar path, so addressing them would have just bogged things down without any meaningful payoff.
