The wide grip incline bench press is a variation of the incline bench press and is used to build the pushing muscles (chest, shoulders, and triceps) of the upper body.
The slight change in hand placement used in the wide grip incline bench press allows the lifter to place more emphasis on the chest muscle during the exercise, when compared to its closer grip counter parts.
The incline used in the wide grip incline bench press also allows one to target the upper chest better. This can be extremely beneficial if your upper chest is a lagging muscle group.
