Introduction
The cable crunch is a popular abdominal exercise that utilizes a cable machine to target the core muscles effectively. It primarily strengthens the rectus abdominis (six-pack muscles) and obliques, enhancing overall core stability and improving posture. This exercise is effective for sculpting defined abs and reinforcing the lower back, making it beneficial for individuals pursuing a toned midsection or seeking to improve their fitness levels, particularly in sports involving agility and power.
Muscles Worked
- Primary: Abdominals (Rectus Abdominis, Transverse Abdominis, and Obliques)
- Secondary: Lower Back Muscles (Erector Spinae), Hip Flexors, Shoulder Stabilizers (Serratus Anterior)
How to Do It (Step-by-Step)
- Sit on a cable crunch machine with your knees tucked under the padding and feet flat on the floor. Grasp the handle(s) with both hands.
- Curve your back slightly and bring your chest towards your pelvis while crunching forward, keeping your elbows in and close to your body.
- Maintain a steady pace, breathe deeply, and avoid swinging or using momentum. Keep the strain on your abdominal muscles throughout the movement.
Tip: To prevent lower back strain, maintain a slight curvature in your lower back and avoid arching it excessively.
Rep & Rest Guidelines
- Strength: 4–6 reps, 2–3 min rest
- Hypertrophy: 8–12 reps, 60–90 sec rest
- Endurance: 12–20 reps, 30–60 sec rest

Form Tips
- Maintain a neutral spine and avoid rounding the back during the exercise. Keep your lower back pressed against the bench or mat.
- Squeeze the abs as you pull the cable handle towards your chest, keeping elbows close to the body. Avoid pulling the neck forward.
- Breathe naturally throughout the movement, exhaling as you crunch and inhaling as you return to the starting position.
When to Use It
- Strengthening the Core: Cable crunch is effective for targeting the abdominal muscles and strengthening the core.
- Low Back Pain Relief: This exercise can help alleviate lower back pain by building abdominal strength to support the spine.
- Enhancing Flexibility: Cable crunch can improve flexibility in the hips and lower back, making it beneficial for those with tightness or limited range of motion.
Workout History allows you to track your exercise progress over time.
A cable crunch primarily works the abdominal muscles, focusing on the rectus abdominis.
Cable crunches reduce strain on your neck and provide continuous resistance throughout the range of motion, increasing effectiveness.
Stand facing the cable machine, hold the rope or handle with both hands, lean forward slightly, and perform the crunch by pulling your elbows towards your knees.
Perform 2-3 sets of 10-15 repetitions for beginners, and gradually increase to 3-4 sets of 15-20 repetitions as you become more advanced.
A weight belt is not typically necessary during cable crunches, as the focus should be on engaging your core muscles for proper form and execution.
