Cable Seated Crunch
The Cable Seated Crunch primarily works the Rectus Abdominis, with secondary activation of the External Obliques. It is a cable isolation exercise at intermediate difficulty.
The Cable Seated Crunch is an intermediate isolation exercise performed with cable, following a flexion movement pattern. It primarily targets the Rectus Abdominis, with secondary engagement of the External Obliques. This is a bilateral pulling movement, engaging both sides of the body simultaneously.

Muscles Worked
The Rectus Abdominis is the primary mover, taking on the bulk of the workload throughout the full range of motion. The External Obliques assists as a secondary mover, contributing to force production without bearing the primary load.
Primary Muscles
- Primary Muscle Rectus Abdominis (core)
Secondary Muscles
- Secondary Muscle External Obliques (core)
How to Perform
Preparation
- Sit with back support away from medium high pulley.
- Grasp cable rope attachment with both hands and place securely over both shoulders.
- Allow weight to lift chest up with spine arched back slightly.
Execution
- With hips stationary, flex waist so elbows travel toward hips.
- Return and repeat.

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. |
