Pull-ups are difficult primarily because the upper body muscles have to lift the significantly larger mass of the lower body against gravity. This resource explains why this fundamental bodyweight exercise is challenging and offers five specific techniques to improve strict pull-up performance. These methods include building grip strength and shoulder mobility through dead hangs, activating the scapula, utilizing holds and slow negatives, using resistance bands for assistance, and practicing segmented (partial) pull-ups to target weak points. The guidance emphasises proper form with a double overhand grip and a focus on controlled movements to increase strength and efficiency.
