The upright row is an exercise that targets the shoulders and upper back, primarily the side delts and traps. It is a compound exercise that uses multiple joints and muscle groups, making it an effective exercise for developing upper body strength. The muscles worked by the upright row include:

• Trapezius
• Deltoids
• Biceps
• Upper back
• Core

While the upright row is a great exercise for building strength, it does have a reputation for causing injury if not performed with correct form. It is important to maintain proper posture and avoid elevating your upper arms above shoulder height at the top of the movement to mitigate the risk of shoulder pain. If you have pre-existing shoulder or neck injuries, it may be best to avoid upright rows and try alternative exercises that target similar muscle groups.
