摘要
AthleanX 的 Jeff Cavaliere 介绍了一个使用单根绳索或弹力带的练习动作，能够在一个流畅的动作中同时训练肱二头肌和肱三头肌。这个练习改编自用于四分卫和投手等投掷运动员的训练动作，强调运动模式与有效增肌之间的内在联系。该动作通过旋转运动将肱二头肌弯举过渡到肱三头肌伸展，同时全程伴随显著的core activation。
核心要点
- 一个动作，两块肌肉：该动作在单次重复中同时训练肱二头肌和肱三头肌，是高效的手臂训练收尾动作
- 运动员训练起源：该练习源自投掷运动员（四分卫、投手）的训练动作，强调旋转与核心参与如何驱动上肢爆发力
- 旋转是核心机制：完成初始弯举后，通过旋转身体并向前驱动肘部，将负荷从肱二头肌转移至肱三头肌
- 双肌群离心负荷：该动作在回程时产生肱二头肌离心收缩，在下降阶段产生肱三头肌离心收缩，最大化肌肉刺激
- 核心主动参与：动作中的旋转激活核心肌群，模拟运动员投掷动作的力学机制
- 器械灵活性：可在绳索机上完成（绳索设置在高位），也可在家中使用固定于稳固结构上的resistance band进行替代训练
动作详情
目标肌肉
- 主要：肱二头肌、肱三头肌
- 辅助：核心肌群（旋转稳定肌）
标准动作要领
- 将绳索或固定点设置在高位，身体与之保持一定距离，仿佛准备做投掷动作
- 以肱二头肌弯举开始，将把手向身体方向拉
- 旋转躯干，并在动作过程中向前驱动肘部
- 面朝正前方后，完成肱三头肌伸展以结束本次重复
- 在两个阶段均缓慢回位——肱三头肌下降时缓慢离心，肱二头肌回程时缓慢离心
- 全程保持动作两个方向上的张力
常见错误
- 在动作任何阶段失去弹力带或绳索的张力
- 省略旋转环节——躯干旋转正是在肌群之间转换发力重心并激活核心的关键
- 离心阶段动作过快，降低肌肉刺激效果及核心训练收益

Summary
Jeff Cavaliere of AthleanX presents a single cable or resistance band exercise that trains both the biceps and triceps in one fluid movement. The exercise is adapted from throwing athlete drills used with quarterbacks and pitchers, emphasizing the connection between athletic movement patterns and effective muscle building. The move incorporates a bicep curl transitioning into a tricep extension through rotational movement, with significant core activation throughout.
Key Points
- One exercise, two muscle groups: The movement trains both biceps and triceps within a single rep, making it an efficient arm workout finisher
- Athletic origin: The exercise is derived from drills used with throwing athletes (quarterbacks, pitchers) to reinforce how rotation and core involvement drive upper body power
- Rotation is the key mechanism: After the initial curl, rotating the body and driving the elbow forward shifts the load from the biceps to the triceps
- Eccentric loading on both muscles: The movement produces eccentric bicep contraction on the way back and eccentric tricep contraction during the lowering phase, maximizing muscle stimulus
- Core is actively involved: Rotation through the movement engages the core, mimicking the mechanics of athletic throwing patterns
- Equipment flexibility: Can be performed at a cable machine (cable set high) or replicated at home using a resistance band anchored to any sturdy structure
Exercise Details
Target Muscles
- Primary: Biceps, Triceps
- Secondary: Core (rotational stabilizers)
Proper Form Cues
- Set the cable or anchor point up high, positioning yourself away from it as if preparing a throwing motion
- Begin with a bicep curl, pulling the handle toward the body
- Rotate the torso and drive the elbow forward through the movement
- Once facing forward, perform a tricep extension to complete the rep
- Return slowly through both phases — slow eccentric on the triceps lowering, then slow eccentric on the biceps return
- Maintain tension in both directions throughout the movement
Common Mistakes to Avoid
- Losing tension in the band or cable at any point during the movement
- Skipping the rotational component — the twist is what shifts emphasis between muscle groups and engages the core
- Rushing the eccentric portions, which reduces both muscle stimulus and the core training benefit
Sets/Reps Recommendations
- No specific sets or reps were mentioned in the transcript; the exercise is presented as a workout finisher
