In contrast, Barnett (1995) reported that
Close Grip Smith Bench Press increases activation of the Triceps and clavicular head of the Pectoralis Major (upper chest). Lahman (2005) found that
Close Grip Bench Press increased triceps activity 210% from that experienced during the wide grip bench press. Some individuals may be able to perform bench press with the upper arm portioned further out without issues due to individual structural differences (Contreras 2011). However, performing bench press with the upper arms positioned close to 90° to the torso is thought to place the shoulder in a potentially vulnerable position, at least for some individuals, particularly when combined with other
Weight Training Injury Risk Factors (Green 2007).
In contrast, positioning the upper arms closer to the body in the lower position is thought to increase the load on the Anterior Deltoid, clavicular head of the Pectoralis Major (upper chest), and Triceps while decreasing involvement of the sternal head of the Pectoralis Major. In this close arm position, the shoulder may have greater mobility with less potential shoulder issues. In fact, those with a history of certain shoulder issues may find that positioning the upper arm closer the the sides does not aggravate their shoulder condition. However, this totally adducted shoulder positioning can also limit the resistance that can be used since this close arm position limits the involvement of the powerful sternal head of the Pectoralis Major while emphasizing the relatively weaker front deltoid, upper chest, and triceps (

Je hebt gelijk en tegelijk ook niet, het ligt er helemaal aan hoe de persoon is gebouwd en hoe zijn benchstijl op dit moment is. De literatuur spreekt hierover spreekt elkaar in ieder geval heel erg tegen. We zouden eigenlijk veel meer informatie moeten hebben, willen we een adecuate oplossing kunnen geven. Wat vaak ook een oplossing is, is meer achterkant schouder trainen en een goede houding hebben, wat vaak de veroorzaker is van schouderproblemen. Maar het kan iig beiden.
