Cable Isolateral Incline Fly
The Cable Isolateral Incline Fly primarily works the Pectoralis Major (Clavicular), with secondary activation of the Anterior Deltoid, Biceps Brachii (Short Head), Brachialis, Pectoralis Major (Sternal) and stabilizer support from the Biceps Brachii (Long Head), Triceps (Long Head), Wrist Flexors. It is a cable isolation exercise at intermediate difficulty.
The Cable Isolateral Incline Fly is an intermediate isolation exercise performed with cable, following a isolation movement pattern. It primarily targets the Pectoralis Major (Clavicular), with secondary engagement of the Anterior Deltoid, Biceps Brachii (Short Head), Brachialis, Pectoralis Major (Sternal). This is a bilateral pushing movement, meaning both sides work together to generate force.

Muscles Worked
The Pectoralis Major (Clavicular) is the primary mover, taking on the bulk of the workload throughout the full range of motion. The Anterior Deltoid, Biceps Brachii (Short Head), Brachialis, and Pectoralis Major (Sternal) act as secondary movers, assisting the primary muscles and contributing meaningfully to the overall output. The Biceps Brachii (Long Head), Triceps (Long Head), Wrist Flexors act as stabilizers, maintaining joint position and postural alignment throughout the movement.
Primary Muscles
- Primary Muscle Pectoralis Major (Clavicular) (chest)
Secondary Muscles
- Secondary Muscle Anterior Deltoid (shoulders)
- Secondary Muscle Biceps Brachii (Short Head) (biceps)
- Secondary Muscle Brachialis (biceps)
- Secondary Muscle Pectoralis Major (Sternal) (chest)
Stabilizer Muscles
- Stabilizer Muscle Biceps Brachii (Long Head) (biceps)
- Stabilizer Muscle Triceps (Long Head) (triceps)
- Stabilizer Muscle Wrist Flexors (forearms)
How to Perform
Preparation
- Sit on seat with stirrups in each hand (attached to low cable pulleys).
- Lie back on incline back support.
- Position stirrups out to each side of chest with bent arm under each wrist.
- Press stirrups over each shoulder until arms vertical.
- Bend elbows slightly and internally rotate shoulders so elbows point out to sides.
Execution
- Lower stirrups outward to sides of shoulders.
- Keep elbows fixed in slightly bent position.
- When a stretch is felt in chest or shoulders, bring stirrups back together in hugging motion above upper chest until stirrups are nearly together Repeat.
Comments
- Keep shoulders internally rotated so elbows point downward at bottom position and outward at top position.
- Shoulder will likely have less range of motion in lower position as compared toFly on flat bench.
Tips & Common Mistakes
- Use a full range of motion — partial reps reduce stimulus on the target muscle.
- Slow down the eccentric (lowering) phase for greater time under tension.
- If you need to swing or cheat, the weight is too heavy — reduce and focus on form.
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 (Pectoralis Major (Clavicular)) and can be substituted based on your equipment or variation preferences.
