Stance Width and the Press by Capt James Rodgers | July 05, 2023 You can reduce the negative effects of bar path errors in the press by widening your stance. That is the only actionable piece of advice in this whole article. What follows is the very wordy discussion on why widening your stance will make your press more efficient. Reading it will improve your understanding, but it is not necessary. Out of the five main lifts in the program, the press is the most sensitive to deviations from the model. In the model, when viewed in the sagittal plane, the barbell remains aligned vertically with the shoulder joint and mid-foot balance point. This prevents unnecessary moment arms from forming to the anterior and the posterior of mid-foot as the barbell is pressed up to lockout. This line from the mid-foot up to lockout can be thought of as a narrow slot. At a heavy-enough weight, once the bar drifts out of this slot due to a technique error, the press will stop dead in its tracks, resulting in a failed rep which otherwise would have been completed if the bar path had stayed in the slot. Keeping the bar path in the slot is a difficult challenge, especially if you are pressing heavy and your brains are starting to leak out of your ears. Now, there are some very obvious things that you can do to make your press as efficient (and as heavy) as possible. First, you can buy a copy of Starting Strength, read the thing, read the thing again paying attention this time, and then finally apply the technique instructions. You can also attend a seminar or a camp hosted by a coach. Or you could go to a Starting Strength Gym or an affiliate gym. If you are far away from in-person coaching you can hire a coach online to fix your press (and all the other stuff you’re doing wrong). Let’s say that you have done everything in your power to make sure that your technique is on point. That means that every rep will be perfectly aligned with the slot, right? No. There will still be an amount of variance with each and every single repetition that you do. This is unavoidable because the overhead press is a sentient pile of a couple trillion cells and at least two social media accounts working as a team to put a heavy thing up as high as it can. There will be some unavoidable inconsistency. You can mitigate against the balance problems that this wobble causes by widening your stance and artificially making yourself shorter. I have a decent press and not a big press. I developed a wider stance over time without really thinking about it. I have noticed that big pressers also used a wider stance. At first I assumed that it was to accommodate our gigantic balls, but there were indications that this was not the case since I saw women doing this too. Now in our brave and stunning modern society I cannot completely rule out women having balls, but I still looked for an explanation that would apply to both sexes. It turns out that there is a simple mechanical reason as to why a wider stance provides an advantage in the press. The wide stance will artificially shorten the legs by turning the leg length from a straight line up and down perpendicular to the ground to a hypotenuse out to the side. This trick is used to great effect by sumo “deadlifters” to reduce the range of motion of the pull. Luckily, widening the stance in the overhead press will not affect the range of motion of the lift, so it is not cheating. It is also the only practical means by which to shorten the lifter during a press. Making your torso shorter is only really possible with industrial or farming accidents and making your arms shorter by widening your grip will introduce those nasty bad moment arms between your hands and shoulders in the frontal plane. Widening the stance is therefore the only feasible method left to make yourself shorter. How does making yourself shorter actually help your press? I will explain with some simple diagrams and then with some trigonometry and mechanics. Here is the simple one. In basic mechanics, a force applied to an object that is offset from the object’s center of mass or its balance point will result in a rotation or turning force called a moment. The straight line up and down is the perfect bar path over the middle of the foot. Forces applied down along that straight line will result in compression, which is fine, it's just supported by the skeleton and requires no work. The angled line in the figure above represents a bar path error. The horizontal line represents the distance between the barbell and the middle of the foot. The amount of moment is the product of the horizontal line and the amount of force applied. You want the horizontal distance to be as little as possible to minimize the moment. As you can see the upper horizontal line is longer than the lower horizontal line, meaning that with the same angular error, there is less resultant moment to overcome. If you are math and physics adverse, just think: flat line big number bad when pick up weight. Unless the flat line is associated with the hips, then we like it. Here comes the trigonometry and mechanics. At lockout, the vertical distance the lifter gets the bar to becomes a potential moment arm. If he is perfectly vertical, the moment arm will be zero. If Spiderman were standing on a wall and pressing a weight perpendicular to the direction of gravity, the moment arm would be the total horizontal length of Spiderman. The horizontal displacement of the weight from the mid-foot is also the length of the moment arm and it can be determined by multiplying the sine of the angle between the vertical and the line from mid-foot to the weight by the length of the lifter from his feet to his outstretched hands at lockout. The formula to determine the moment is simply that horizontal distance multiplied by the force applied at the hands (the barbell). We have a lifter who is pressing 200 lb and at lockout will have hands reaching up to a total height of 80 inches. With a wider stance, he reduces the height at lockout to 76 inches. He also has a tendency to lock out behind mid foot sometimes, resulting in an angle between the ideal vertical bar path and a line formed between the mid foot and the final position of the barbell of two degrees. The first step will be to determine the horizontal length of the moment arms at the two heights. Normal Stance Horizontal distance = sin(angle) x lengthHorizontal distance = sin(2) x 80 inHorizontal distance = 2.8 in Wider Stance Horizontal distance = sin(angle) x lengthHorizontal distance = sin(2) x 76 inHorizontal distance = 2.6 in The next step is to determine the amount of moment force that results from the two stances. Normal Stance Moment = Moment arm length x forceMoment = 2.8 in x 200 lbMoment = 560 in*lb Wide Stance Moment = Moment arm length x forceMoment = 2.6 in x 200 lbMoment = 520 in*lb After that, it is simple matter to find out that the wider stance results in a moment force about the mid-foot that is 40 in*lb less than the narrow stance, or an approximately 7% relative reduction of the moment loading resulting from an error at lockout. Small distances become significant quickly. Now we need to go over the far more common press error of the shoulders getting too far away from the bar in the sagittal plane. Widening your stance will not help with this. Remember, in the most mechanically efficient press, the mid-foot, shoulder joint, and barbell all remain aligned vertically. The press is taught with a hip bounce to get the face out of the way of this vertical line and to provide a stretch reflex to get the weight started upward. Oversimplified presses seen from the side. The figure on the left has laid back which has created an unnecessary moment arm between the shoulder and the barbell. The figure on the right has brought his hips forward while keeping his shoulder in line with the barbell and midfoot, loading the hip, trunk and leg musculature while avoiding a moment arm between the shoulder and barbell. A lifter can commit the error of throwing his shoulders back, instead of reaching forward with his hips. This will create a longer horizontal distance between the shoulder and the barbell, which results in an unnecessarily long moment arm about the shoulder, resulting in a failed lift. Remember that we operate moment arms to move loads – they are our mechanical tools for applying and multiplying force. But if the moment arm gets longer than it must be, the load multiplies its force against us, and it takes more force to move it than if the leverage is efficient. If you lay back too far, even a light weight gets hard to press if the moment arm against your shoulder is too long. Think about reaching forward with the hips, not laying the shoulders back. If you've made it this far, thanks for reading. Discuss in Forums
