Most dip stations give you one bar width. You either fit it or you don't. That width is not based on your shoulders. It is based on manufacturing convenience. Gymnastics figured out the problem years ago and solved it with adjustable parallel bars. Most home fitness companies have not caught up.
The International Gymnastics Federation (FIG) sets parallel bar spacing at 42 to 52 centimeters, and that spacing is adjustable. Coaches change the width for every gymnast before every routine. A 5-foot-2 gymnast does not train on the same bar width as a 6-foot-4 gymnast. Nobody hands a young gymnast a fixed 24-inch station and says, "Just deal with it."
Yet that is exactly what most home dip stations ask you to do. A fixed 24-inch spacing is 61 centimeters. That is 9 centimeters wider than the widest FIG parallel bar setting. The widest setting a gymnastics federation allows for parallel bars is 52 centimeters. Most home dip bars are locked at 61. That is wider than what the sport's own equipment standards consider appropriate for the broadest-shouldered athletes.
Your shoulders are not average. Standard anthropometric references list adult biacromial breadth at 36 to 40 centimeters. That is the distance between the bony tips of your shoulders, roughly 14 to 16 inches. A 61-centimeter dip bar spacing puts your hands 21 to 25 centimeters outside your biacromial breadth. Your hands end up well outside your elbows at the bottom of a dip, forcing excessive horizontal abduction at the shoulder joint, and that position loads the front of the shoulder capsule and the AC joint in ways they were not designed to handle.
One quick test to see if your dip bars are too wide
Stand in front of a mirror with your arms straight out to your sides at shoulder height. Bend your elbows to 90 degrees and lower your torso slightly, like you are at the bottom of a dip. Look at your hands relative to your elbows. If your hands sit outside your elbows, the bars are too wide for your frame. That is the position most fixed stations force. That is where shoulder impingement risk climbs.
Biomechanics research on pressing movements consistently shows that wider hand spacing increases horizontal abduction at the shoulder and increases stress on the supraspinatus tendon and the long head of the biceps. Those are the two structures most often involved in shoulder impingement. Dips have not been studied as heavily as bench press, but the joint mechanics are the same. When your humerus moves back and out at the bottom of a dip, the tendons and bursa in the subacromial space get compressed. Do that for hundreds of reps over months, and the shoulder starts to complain.
Fixed dip stations are cheaper to manufacture. Two bars welded at a single distance. No adjustment mechanism. No extra hardware. That is a manufacturing decision. It has nothing to do with your anatomy. A 5-foot-6 lifter and a 6-foot-2 lifter are expected to use the same 24-inch spacing. One of them will be compromised. The smaller lifter will flare their elbows just to reach the bars, and that flare becomes shoulder pain over time. The taller lifter might find the bars too narrow to hit their chest, and they will compensate by leaning further forward. Neither gets a dip that fits.
What adjustable dip bars actually change
The BULLBAR 2.0 takes the other approach. Its dip bars slide between 21 and 24 inches. You set the width to match your shoulders, not the reverse. That three-inch range covers most adult frames, from smaller lifters to broad-shouldered athletes. The adjustment takes seconds. Loosen the toggle, slide the bar, lock it in. No tools, no guesswork.
To find your ideal dip bar width, start with your hands directly under your shoulders in the bottom position. Your elbows should point back at about 45 degrees, not flared out to your sides. If the bars force your elbows wider than that, narrow the setting. If your wrists collide with your hips, widen it. A good cue: in the bottom position, your forearm should stay vertical when viewed from the front. That vertical forearm keeps the load over your wrist and elbow, not hanging off the side of your shoulder where it recruits the wrong muscles and stresses the joint capsule.
Setting dip bar height
Height matters as much as width. If the dip bars are too high, you cannot touch the floor with your feet, which turns the dip into a free-hanging movement. That increases shoulder stress at the top because you cannot use your legs to control the descent. If the bars are too low, your knees hit the ground before you reach full depth, cutting your range of motion short. The BULLBAR 2.0 has three height settings for the dip bars. That lets you set the bars high enough for full range but low enough to keep control.
- Stand between the bars and set them at mid-thigh height as a starting point.
- Grip the bars and lower into the bottom position. Watch your elbows.
- If your elbows flare beyond 45 degrees, narrow the bar spacing.
- If your wrists hit your hips at the bottom, widen the spacing.
- Lock the toggles and repeat a few reps to confirm.
What adjustable bars give you is the ability to train consistently without fighting your own equipment. When the bar width matches your shoulders, your elbows track naturally, your triceps and chest do the work, and your shoulders stay in a position they can handle. You can add volume without adding joint pain. You can progress from assisted dips to full bodyweight dips to weighted dips without changing your mechanics. That is the whole point.
Fixed-width dip stations are a compromise built for manufacturing convenience, not for your shoulders. Gymnastics has known for decades that parallel bars need to adjust. The rest of the fitness industry is slowly catching up. If you train on a fixed-width station, measure your shoulders, compare it to the bar spacing, and if there is a mismatch, consider an adjustable solution. Your shoulders train every rep. The bar should fit them.
