自重三头肌训练：6分钟让你酸痛到位
概要
ATHLEANX 的 Jeff Cavaliere 介绍了一套仅需 6 分钟、无需任何健身器材的纯自重三头肌训练。该训练只包含两个动作——眼镜蛇俯卧撑和走入式三头肌伸展——循环进行三轮。整套训练的难度随疲劳积累逐步降低，适合各种健身水平的人群。
要点
- 无需任何器材 —— 动作可利用沙发背部、床沿或家中任何类似的平面来完成
- 三头肌被描述为一个相对较小的肌群，无需负重即可轻松实现超负荷
- 训练由两个动作重复三轮构成，合计六分钟
- 每轮采用一分钟计时制 —— 尽快完成眼镜蛇俯卧撑，该分钟内剩余的时间即为休息时间
- 眼镜蛇俯卧撑采用 21 次法的动作结构：底部范围 7 次、顶部三分之一范围 7 次、全程 7 次
- 为应对疲劳，难度随轮次递进降低：双脚抬高（第 1 轮）→ 双脚平放地面（第 2 轮）→ 跪姿（第 3 轮）
- 走入式伸展采用慢速离心收缩，以最大化三头肌的参与，尤其是长头部分
- 若在伸展过程中力竭，可将双脚向支撑面走近以减轻负荷，继续完成动作
动作详解
1. 下斜眼镜蛇俯卧撑（21 次法）
- 目标肌群： 三头肌（主要）
- 准备姿势： 双脚抬高置于沙发、床或架子上，形成下斜姿势
- 动作结构（21s method）：
- 在动作底部三分之一范围内完成 7 次
- 在动作顶部三分之一范围内完成 7 次
- 全程动作完成 7 次
- 各轮进阶：
- 第 1 轮 —— 双脚抬高
- 第 2 轮 —— 双脚平放地面
- 第 3 轮 —— 跪姿完成
- 目标： 在一分钟时间窗口内尽快完成全部 21 次；剩余时间用于休息
2. 走入式自重三头肌伸展
- 目标肌群： 三头肌，因拉伸姿势特别强调 long head of the triceps（三头肌长头）
- 准备姿势： 双手撑于抬高平面（沙发、床等）顶部，身体呈一定角度向外延伸
- 动作要点：
- 以受控的eccentric contraction（离心收缩） 缓慢下降
- 在底部充分拉伸三头肌长头
- 推回起始位置
- 难度调节： 随疲劳积累，将双脚向支撑面走近，缩短力臂以减轻难度
- 持续时间： 每轮持续进行整整一分钟
- 常见错误： 下降过快 —— 缓慢的离心过程是动作有效性的关键

Bodyweight Triceps Workout: Sore in 6 Minutes
Summary
Jeff Cavaliere of ATHLEANX presents a 6-minute bodyweight-only triceps workout requiring no gym equipment. The routine uses just two exercises — the cobra pushup and the walk-in tricep extension — performed in a repeating circuit three times. The workout is structured to progressively reduce difficulty as fatigue builds, making it scalable for all fitness levels.
Key Points
- No equipment required — exercises can be performed using a couch back, the top of a bed, or any similar household surface
- The triceps are described as a relatively small muscle group that is easy to overload without weights
- The workout consists of two exercises repeated across three rounds, totaling six minutes
- Each round follows a one-minute-on format — finish the cobra pushups quickly and the remaining time within that minute serves as your rest
- The cobra pushup is performed using 21-style rep structure: 7 reps in the bottom range, 7 reps in the top third, and 7 full reps
- Difficulty is progressively reduced across rounds to account for fatigue: feet elevated (round 1) → feet flat on floor (round 2) → on knees (round 3)
- The walk-in extension uses a slow eccentric contraction to maximize tricep engagement, particularly the long head
- If you fatigue during the extension, walk your feet in toward the surface to reduce the load and keep repping
Exercise Details
1. Decline Cobra Pushup (21 Style)
- Target muscles: Triceps (primary)
- Setup: Feet elevated on a couch, bed, or rack for a decline position
- Rep structure (21s method):
- 7 reps through the bottom third of the range of motion
- 7 reps through the top third of the range of motion
- 7 full range-of-motion reps
- Progression across rounds:
- Round 1 — feet elevated
- Round 2 — feet flat on the floor
- Round 3 — performed from the knees
- Goal: Complete all 21 reps as fast as possible within the one-minute window; remaining time is rest
2. Walk-In Tricep Bodyweight Extension
- Target muscles: Triceps, with emphasis on the long head of the triceps due to the stretch position
- Setup: Hands placed on the top of the elevated surface (couch, bed, etc.), body extended outward at an angle
- Form cues:
- Lower yourself slowly using a controlled eccentric contraction
- Allow the long head of the tricep to fully stretch at the bottom
- Press back up to the start position
- Scaling: Walk feet closer to the surface to shorten the lever and reduce difficulty as fatigue accumulates
- Duration: Performed continuously for one full minute per round
- Common mistakes to avoid: Rushing the descent — the slow eccentric is key to effectiveness
Workout Structure
| Round | Cobra Pushup Variation | Extension Duration |
|---|---|---|
| 1 | Feet elevated, 21 style | 1 minute |
| 2 | Feet flat, 21 style | 1 minute |
| 3 | On knees, 21 style | 1 minute |
Total time: 6 minutes
