早安運動 Good Morning

雖然這些研究沒有直接討論早安動作，但從硬舉和其他髖關節動作來看，早安主要練到後鏈肌群。不過因為負重位置在肩膀，能用的重量有限，所以肌肥大效果比不上硬舉或深蹲。 While not directly studied in these papers, good mornings target posterior chain muscles similarly to deadlifts. However, the barbell position limits the load you can use compared to deadlifts or squats, making it less optimal for hypertrophy.

早安動作可以強化髖關節鉸鏈動作模式，對改善硬舉技術有幫助。但因為槓鈴在背上增加脊椎負擔，所以通常當作輔助動作來練，不太適合追求最大力量。 Good mornings can strengthen the hip hinge pattern and improve deadlift technique. However, the barbell position creates spinal loading that limits how heavy you can go, making it better as an accessory movement rather than a primary strength exercise.
