Cable Preacher Curl
The Cable Preacher Curl primarily works the Brachialis, with secondary activation of the Biceps Brachii (Long Head), Brachioradialis and stabilizer support from the Wrist Flexors. It is a cable isolation exercise at intermediate difficulty.
The Cable Preacher Curl is an intermediate isolation exercise performed with cable, following a flexion movement pattern. It primarily targets the Brachialis, with secondary engagement of the Biceps Brachii (Long Head), Brachioradialis. This is a bilateral pulling movement, engaging both sides of the body simultaneously.

Muscles Worked
The Brachialis is the primary mover, taking on the bulk of the workload throughout the full range of motion. The Biceps Brachii (Long Head), and Brachioradialis act as secondary movers, assisting the primary muscles and contributing meaningfully to the overall output. The Wrist Flexors act as stabilizers, maintaining joint position and postural alignment throughout the movement.
Primary Muscles
- Primary Muscle Brachialis (biceps)
Secondary Muscles
- Secondary Muscle Biceps Brachii (Long Head) (biceps)
- Secondary Muscle Brachioradialis (biceps)
Stabilizer Muscles
- Stabilizer Muscle Wrist Flexors (forearms)
How to Perform
Preparation
- Sit on preacher bench placing back of arms on pad.
- Grasp cable bar with shoulder width underhand grip.
Execution
- Raise cable bar toward shoulders.
- Lower cable bar until arms are fully extended.
- Repeat.
Comments
- Seat should be adjusted to allow armpit to rest near top of pad.
- Back of upper arm should remain on pad throughout movement.
- The long head (lateral head) of Biceps Brachii is activated significantly more than short head (medial head) of Biceps Brachii since short head enters intoactive insufficiencyas it continues to contract.
- At bottom position, weight stack in use should not make contact with remaining weight stack.
- Also see movement onhorizontal pad.
Tips & Common Mistakes
- Control the eccentric phase — the lowering portion drives significant muscle development.
- Avoid momentum; focus on feeling the target muscle work through the full range.
- Full range at both ends maximizes stretch at the bottom and contraction at the top.
Programming Suggestions
Adapt your sets and reps to your training goal.
| Strength | 3–4 sets × 6–8 reps at 75–85% 1RM with 90–120 seconds rest. |
|---|---|
| Hypertrophy | 3–4 sets × 10–15 reps at 60–75% 1RM with 60–90 seconds rest. |
| Endurance | 2–3 sets × 15–25 reps at 40–60% 1RM with 30–45 seconds rest. |
Alternative Exercises
These exercises target the same primary muscles (Brachialis) and can be substituted based on your equipment or variation preferences.
