Perform face pulls at the end of workouts (2 to 3 sets of 10 to 15 repetitions, several times a week) to strengthen the rear deltoids, rotator cuff, and lower trapezius, which would purportedly guarantee a natural, effortless upright posture and stable shoulders.

The efficacy of the face pull for muscle activation is solidly validated by biomechanical research. Electromyography (EMG) analyses, such as those synthesized by the National Academy of Sports Medicine (NASM), confirm that this movement effectively targets the posterior deltoid, external rotators, and middle and lower trapezius. This strengthening helps balance the tensions generated by prolonged seated postures in front of a screen. However, claiming that this exercise alone guarantees an upright posture by default 'without thinking about it' and improves breathing is an exaggeration. Observational and interventional studies on slumped posture emphasize that postural correction is comprehensive, involving ergonomics, stretching, and mobility of the entire torso. A single movement, however excellent, cannot serve as a universal miracle solution for posture.
