Targeted Muscle Groups: Triceps brachii (lateral and medial heads), anterior deltoids, and pectoralis major.
Tempo (3-1-1-0): 3 seconds eccentric lowering to lower sternum, 1 second pause at bottom, 1 second explosive drive upward, 0 seconds lockout rest.
Rest: 120 seconds between heavy working sets.
Note: Close-grip pressing shifts the primary mechanical load from the pectorals onto the triceps brachii, maximizing triceps cross-sectional mass recruitment. Keep your elbows tucked close to your torso during the descent to isolate the triceps heads.
