The Eccentric Tarzan Pull-Up focuses on the lowering (eccentric) phase of the movement, which is performed slowly to maximize muscle engagement. Start by gripping a pull-up bar with both hands, using an alternating grip (one hand overhand, the other underhand). Pull yourself up until your chin is above the bar, then slowly lower yourself in a controlled manner over several seconds. This exercise targets the biceps, lats, and forearms while enhancing grip strength.
