摘要
Jeff Cavaliere 介绍了一种名为”接力上举”（relay raise）的绳索或弹力带动作，专为最大化前三角肌的牵张反射而设计。通过在动作起始位置将手臂置于身体后方，该动作克服了传统哑铃前平举的局限性——传统动作会被大腿阻挡。此外，该动作还有一个附加益处：在整个运动过程中核心肌群会持续主动参与。
要点
- 传统前平举受到限制：使用哑铃时会被大腿阻挡，限制了活动范围，并降低了前三角肌的拉伸效果
- 牵张反射被强调为关键因素，原因有二：它能产生更强的肌肉收缩，并因拉伸位置下的张力而造成更大的微细胞肌肉损伤
- 接力上举使用低位绳索或弹力带，使手臂能够移动至身体后方，在上举开始前对前三角肌形成真正的拉伸
- 在整个动作过程中保持肘关节固定弯曲90°至关重要——伸直手臂会将发力转移至肱三头肌，而非孤立前三角肌
- 该动作被命名为”接力上举”，因为手臂姿势模仿了接力赛中传递接力棒的动作
- 该动作的次要益处是核心肌群明显激活
- 此处应用的原则被描述为**“将科学融入力量训练”**——运用生物力学优化目标肌肉的刺激
动作详解
动作名称：接力上举（Relay Raise）
目标肌肉
- 主要肌肉：前三角肌（anterior deltoid）
- 辅助肌肉：核心肌群／腹肌
所需器械
- 低位绳索滑轮或弹力带
正确动作要领
- 将绳索或弹力带固定于低位锚点
- 握住把手，使肘关节保持90°角
- 向前跨步，使训练手臂在动作底部向后伸展至身体后方——这样可以拉伸前三角肌
- 将手掌向上举向天花板，全程保持肘关节角度不变
- 上举过程中不要伸直手臂——保持弯曲状态
- 以受控方式下降回到拉伸位置，再进行下一次重复
常见错误
- 上举时伸直／打开肘关节——这会募集肱三头肌，降低前三角肌的孤立效果
- 不使用绳索／弹力带而改用哑铃——这会限制活动范围并消除底部拉伸
- 跨步不够大，导致手臂在底部无法越过躯干后方
组数／次数
- 本视频中未作具体说明
涉及概念
- stretch reflex
- anterior deltoid
- front raise
- muscle hypertrophy
- time under tension
- core activation
- isolation exercise

Summary
Jeff Cavaliere introduces the “relay raise,” a cable or band exercise designed to maximize the stretch reflex for the front deltoid. By positioning the arm behind the body at the start of the movement, the exercise overcomes the limitation of traditional dumbbell front raises, which are blocked by the thighs. As a bonus, the core is actively engaged throughout the movement.
Key Points
- Traditional front raises are limited by the thighs when using dumbbells, restricting the range of motion and reducing the stretch on the front deltoid
- The stretch reflex is emphasized as critical for two reasons: it produces a stronger muscular contraction and creates greater microcellular muscle damage due to the elongated position under tension
- The relay raise uses a low cable or resistance band to allow the arm to travel behind the body, creating a true stretch on the front deltoid before the lift begins
- Maintaining a fixed 90° bend in the elbow throughout the movement is essential — extending the arm would shift work to the tricep rather than isolating the front delt
- The movement is named “relay raise” because the arm position mimics handing off a baton during a relay race
- The core is visibly activated as a secondary benefit during the exercise
- The principle applied here is described as “applying the science to the strength” — using biomechanics to optimize muscle targeting
Exercise Details
Exercise: Relay Raise
Target Muscles
- Primary: Front deltoid (anterior deltoid)
- Secondary: Core/abdominals
Equipment
- Low cable pulley or resistance band
Proper Form Cues
- Set the cable or band at a low anchor point
- Grip the handle and establish a 90° angle at the elbow
- Stride forward so the working arm travels behind the body into extension at the bottom of the movement — this creates the stretch on the front delt
- Raise the hand upward toward the ceiling, keeping the elbow angle consistent throughout
- Do not straighten the arm during the raise — keep the bend maintained
- Lower back into the stretched position in a controlled manner before the next rep
Common Mistakes to Avoid
- Extending/straightening the elbow during the raise — this recruits the tricep and reduces front delt isolation
- Using a dumbbell without the cable/band setup — this limits the range of motion and eliminates the bottom stretch
- Not striding out far enough to allow the arm to pass behind the torso at the bottom
