What a row asks of the shoulder, and what no study has countedEmerging evidence
In every row except the upright row, your arm pulls back from in front of you towards your side, below shoulder height, with the lats, the muscles between the shoulder blades (the rhomboids and middle and lower trapezius), the back of the shoulder and the biceps. Reviews list rowing among the exercises that work the rotator cuff and shoulder blade muscles hard, and physiotherapists use rows early in shoulder rehab because the arm stays low; in models built from scans, the rotator cuff was squeezed least with the arm low.
The upright row is different: it lifts the arm out to the side while the arm is turned in, the position linked with impingement signs in weight trainers.
No study counts shoulder pain from any row, and none compares grips or row types against pain: a 2026 review of 23 studies of pulling exercises notes "the near-total absence of longitudinal training and injury-outcome data". So the map on this page comes from condition studies, lab studies of muscle activity and shoulder position, studies of weight trainers' shoulders, trials of rotator cuff related pain and NHS pages.

Where it hurts, and who gets itEmerging evidence
No study gives the share of each cause in rows. In general, rotator cuff problems are the commonest cause of shoulder pain: the NHS lists tendonitis, bursitis and impingement for pain that is often worse while using the arm, and the UK shoulder surgeons' pathway calls this pain mostly self-limiting. Pain on top at the end of the collarbone is the AC joint, which in lifters pressing brings on more than pulling. An ache under the shoulder blade is usually the muscles there, but shoulder blade pain was reported in 72% of studies of a trapped nerve in the neck, sometimes weeks before arm pain, and NHS inform says neck problems can cause pain in the shoulders, arms and upper back.
The people it usually bothers, in our reading: people who add load, volume or a new row quickly; people with a shoulder already sore from pressing, raises or overhead work; and people who pull the bar high or yank the last reps. Lifters as a group train their pressing muscles more than the outward rotators and lower trapezius (90 men), and lifters with impingement signs had weaker outward rotators and lower trapezius (55 men, 24 with signs). These are snapshots, so they show a link, not a cause.

Upright rows: what the evidence does and doesn't sayMixed evidence
In 77 men, 46 of them weight trainers, signs of impingement went with upright rows and lateral raises taken above 90 degrees, and less often with training the muscles that turn the arm out; a snapshot like this can't show cause. In 13 young adults without shoulder problems, holding the arm at shoulder height and turned fully in squeezed the structures under the shoulder's roof at 21.3 N, against 3 N or less turned neutral or out; in 12 volunteers, the narrowest point of the space then sat over the most vulnerable part of a rotator cuff tendon. These were still, unloaded arms.
An expert column in the National Strength and Conditioning Association's (NSCA's) journal advises pulling to just below shoulder height and, with impingement pain, to a height that doesn't bring on symptoms or not at all; a hospital handout says hands at least 12 inches (about 30 cm) apart and elbows no higher than the shoulders. On the other side: no study has counted injuries from upright rows, reviews say how high the arm goes matters more than how it is turned, a 2026 review argues the narrowing follows rotator cuff problems rather than causing them, and upright rows were one of five exercises in a programme for women with neck muscle pain. A wider grip worked the deltoids and trapezius harder and the biceps less in 16 men, a muscle activity finding that says nothing about safety.
So "upright rows always cause impingement" overstates it, and "leave them out while your shoulder hurts, and bring them back wide and to shoulder height" fits the evidence.

The front of the shoulder at the end of the pullEmerging evidence
We found no lab, modelling or clinical study of the shoulder when the elbow is pulled far behind the body in a row. The nearest is a study of women with very loose shoulders, in whom pulling the arm back moved the ball of the joint upward. Coaches disagree: some say the elbow shouldn't pass the side of the trunk in a row, others say pull the shoulders back hard. Stopping the pull as the elbow reaches your side while the front of the shoulder hurts is our suggestion, untested.

What a scan shows, and when it mattersStrong evidence
Not at first for an ache at the front or outside of the shoulder: the British Elbow and Shoulder Society's (BESS's) pathway says the diagnosis is clinical and "Additional imaging is not essential to confirm the diagnosis or start treatment", with X-rays after an injury, with warning signs, for severe pain or stiffness, for suspected AC joint arthritis or for pain lasting more than four weeks. Rotator cuff changes rise from 9.7% of people aged 20 and under to 62% at 80 and over, whether or not they hurt, and in a village of 664 people two in three full-thickness tears caused no symptoms.
A test matters after a dislocation (hospital treatment), for sudden weakness after a jerk (a possible tear), for a pop at the front of the elbow (an examination the same day), for a suspected lat or teres major tear, for a shoulder blade that suddenly sticks out (nerve tests), and for pain that hasn't improved by 12 weeks, which the pathway says should lead to a specialist referral.

How it usually goesStrong evidence
No study follows shoulder pain from rows. The UK pathway says rotator cuff related pain is usually self-limiting and "most symptoms respond within three months". The NHS says you usually need to look after it for 2 weeks before it starts to ease, and that shoulder pain can take 6 months or longer to recover. In a UK trial of 708 adults, pain and function improved over time whatever the treatment. NHS inform expects neck problems to begin to settle within 8 weeks. No one can promise a date.
