Frequently Asked Questions
Why does bench press shoulder impingement happen to lifters who have been pressing for years without pain?
Mechanical impingement is cumulative. Subacromial clearance does not collapse overnight — it erodes as pressing volume accumulates without matched scapular stabilizer and external rotator training. Kolber et al. found that bench volume without proportional external rotator work decreased acromiohumeral distance over time, meaning the corridor through which the supraspinatus travels narrows progressively. Years of pain-free pressing can precede impingement onset because the structural deficit builds slowly until a threshold is crossed.
What grip width actually prevents subacromial compression during pressing?
Grip at or below 1.5 times your biacromial distance — the span between the lateral edges of your acromion processes. Fees et al. demonstrated that this width keeps shoulder abduction below 75 degrees and subacromial clearance above 6 mm, both of which are the critical thresholds for avoiding mechanical contact between the supraspinatus tendon and the coracoacromial arch. For most adults, this places the hands roughly at or just inside the outer knurling rings of a standard barbell.
Should I tuck my elbows completely when pressing to protect my shoulders?
Not completely — 45 to 60 degrees from the torso is the target range, not a full tuck. Full elbow tuck (elbows near the ribs) shifts the movement toward a close-grip press and reduces pectoral recruitment substantially. The 45 to 60 degree range keeps shoulder abduction well below the 75-degree threshold identified by Fees et al. while maintaining effective pectoral loading. Vertical forearms at the bottom of the press, viewed from the end of the bench, are a reliable visual confirmation that elbow angle is within this range.
How long does recovery from pressing-related shoulder impingement take?
Mechanical bench press shoulder impingement caught early — before bursitis or tendon pathology develops , typically resolves in four to eight weeks with load reduction, form correction, and targeted scapular stabilizer and external rotator work. Once subacromial bursitis or partial-thickness rotator cuff tears are present, recovery extends to three to six months or longer depending on severity. A sports medicine physician or physical therapist should assess any shoulder pain that persists beyond two weeks of modified training, as imaging may be needed to rule out structural pathology before returning to full pressing load.
