    # TDT Lab 17:追求更好的髖鉸鏈?試試直腿硬舉 ![](https://i.imgur.com/YjK0V2w.png) - https://www.instagram.com/p/CMCPpoissoO/ #直腿硬舉 (Stiff-leg Deadlift),顧名思義,這是一個髖鉸鏈動作,在執行時下肢須盡可能維持平直,在能控制重心落於腳掌中心的情況下,盡可能打開膝角,做出最大程度的髖鉸鏈,且重量不需緊靠著膝蓋/脛骨。 你可能會想問:直腿硬舉跟 RDL 的差別是什麼?從定義上來說,直腿硬舉也算是 RDL 的一種——皆會經歷離心-向心的行程。以我的經驗來說,直腿硬舉應該被視為「進階版」的 RDL。 為什麼直腿硬舉應該視為進階版 RDL 呢?原因我認為是以下三點: 👉 直腿硬舉具有較大的膝角,雙關節的膕繩肌會被拉更長,對活動度的考驗更大 👉 直腿硬舉具有比較大的「抗力臂」——也就是重量與身體重心的垂直距離,根據槓桿原理,在施力臂不變的條件下,需要更大程度的後側鏈發力,必然徵召更多腿後肌群。 👉 直腿硬舉需要更佳的核心穩定能力以避免胸椎/腰椎代償。同時,因為沒有參考標的,例如手腕接觸膝蓋,必須完全由本體感覺維持重心。 在之前的貼文:《下肢訓練容易腰痠?試試單側 RDL》這篇中我們曾學習過單側 RDL 的好處。而無論是 RDL,或者是進階版的直腿硬舉,它們最主要的任務都是「動態拉伸」:喚醒髖鉸鏈,並打開後側活動度。 如果想追求更好的髖鉸鏈品質,請記得將 #直腿硬舉 排入你的訓練計畫中! --- 在軟體開發中,有所謂的測試驅動開發(Test-Driven Development,TDD),而這一套哲學也被我應用在教學中——我稱之為「測試驅動訓練法」(Test-Driven Traning,TDT)。訓練進步的標準的不是舉多重,而是執行每一個動作時有多「準確」,就像跑軟體測試一樣。如果發生偏離「準確」的失誤,就針對失誤進行修正,直到符合「準確」為止。 --- #TDTLab #TestDrivenTraining #健身房就是實驗室 #健身 #訓練 #健身教練 #ironaddict ###### tags: `tdtlab`
