槓鈴臥推 Barbell Bench Press
研究排名 Research Rankings
胸 Chest
最多證據支持的胸肌訓練動作。多項研究顯示高度胸大肌激活，且全程動作產生更多機械功（每次重複283J vs 部分動作164-205J）。可透過握距變化調整肌肉激活模式 Most evidence-supported chest exercise. Multiple studies show high pectoralis major activation, and full ROM produces more mechanical work per rep (283J vs 164-205J for partials). Grip width allows activation customization
允許最大負重，研究顯示拱背姿勢可增加約4.2kg的1RM表現。標準化動作模式便於追蹤進步 Allows maximal loading, research shows arched position increases 1RM by ~4.2kg. Standardized movement pattern facilitates progress tracking
研究顯示平躺臥推比上斜臥推產生更高的動作速度。80% 1RM配合快速意圖可最大化胸肌激活 Research shows horizontal bench produces higher velocities than incline. 80% 1RM with maximal velocity intent maximizes chest activation
借力風險 Compensation Risk
握距過窄增加三頭肌參與（33%），肩胛不穩定時前三角肌代償 Narrow grip increases triceps involvement (33%), anterior deltoid compensates with unstable scapulae
新手建議 Beginner Tips
從空槓開始學習動作模式，確保肩胛後收下壓 Start with empty bar to learn movement pattern, ensure scapular retraction and depression
