The upright row is a weight trainingexercise performed by holding a grips with the overhand grip and lifting it straight up to the collarbone. This is a compound exercise that involves the trapezius, the deltoids and the biceps. The narrower the grip the more the trapezius muscles are exercised, as opposed to the deltoids.
In the 70s there are examples of this exercise being referred to as pullups though this is no longer common.

Due to the amount of internal rotation of the humerus during this movement, many trainers and organizations (such as the ACSM and NFPT) consider this a contraindicated exercise for all trainees. Most will at least advise those with shoulder impingement issues to avoid it. Abstaining from raising the bar above the chest line will help in avoiding injury or symptoms related to rotator cuff impingement.  If pain arises, stop this exercise immediately, as it may be an indicator of a rotator cuff disorder. Substitutes include shoulder shrugs for upper trapezius development and lateral raises for lateral deltoids.
