@samfitnesstt: Scientific reasoning supports these technique cues because electromyography (EMG) studies have shown that shoulder position and movement pattern can significantly influence muscle activation. Research shows that initiating the movement with slight scapular elevation and then leading with the elbows can improve recruitment of the posterior deltoid and upper-back musculature. Performing the exercise on a 45° incline bench increases stability, reduces momentum, and allows the rear delts to work through a greater effective range of motion. Controlling the eccentric (lowering) phase further increases time under tension, a key factor for muscle hypertrophy and strength development. #RearDelt #RearDelts #ShoulderTraining #PosteriorDeltoid #Hypertrophy
