Compound movement that loads pecs, front delts, and triceps simultaneously. The barbell allows micro-loading for progressive overload — the most reliable long-term driver of hypertrophy. Placed third because you benefit from the pre-fatigue of exercises 1 and 2: the pecs are already taxed, so the bench press becomes pec-limited rather than triceps-limited.
Progressive overload potential 15/15 — barbell allows 0.5 kg increments with micro-plates, the highest overload granularity of any equipment type.
Muscle activation breadth 11/15 — pectorals, anterior deltoids, and triceps are loaded through the 6:1 pec lever and the 10:1 triceps lever simultaneously. No isolation exercise matches this multi-joint stimulus.
Lever ratio 6:1 — 100 kg on the bar creates approximately 600 N of pectoral tension at the sticking point (where the moment arm is longest, typically 3–5 cm off the chest).
Scored B (65), not A — the scoring correctly identifies the bench press's weakness: at lockout the bar stacks above the shoulder joint, sin(θ) approaches zero, and pec tension drops to near-nothing. This dead spot means ~30% of each rep provides minimal hypertrophy stimulus. The cable and fly exercises above have no such dead spot.
