Cable Lying Triceps Extensions

Overview

This movement is performed on a bench using a cable machine, providing constant tension on the triceps throughout the entire range of motion. It is an effective alternative to free-weight skull crushers, offering more controlled resistance and reducing strain on the elbows. It is beneficial for anyone who wants to improve arm strength, aesthetics and pushing power.

How to Perform Cable Lying Triceps Extensions

1. Set Up the Equipment

   • Attach a straight bar or EZ-curl bar to a low pulley cable machine.
   • Position a flat bench a few feet away from the cable stack.

2. Starting Position

   • Lie flat on the bench with your feet planted on the floor.
   • Grab the bar with a shoulder-width overhand grip and extend your arms so the bar is above your forehead.
   • Keep your elbows slightly bent but locked in position.

3. Execution

   • Slowly lower the bar towards your forehead or slightly behind it by bending at the elbows.
   • Keep your upper arms stationary while engaging your triceps.
   • Once you reach a 90-degree angle at the elbows, pause briefly.
   • Extend your arms back to the starting position by pushing the bar upward, fully contracting the triceps.

4. Repetitions and Sets

   • Perform 3 to 4 sets of 8 to 12 repetitions, depending on your training goals.

Tips for Proper Form

1. Keep your elbows stationary to maximize triceps activation.
2. Use a controlled motion to avoid momentum and unnecessary strain on the joints.
3. Engage your core to stabilize your body throughout the movement.
4. Lower the weight slowly and under control, ensuring full range of motion.
5. Do not lock out your elbows at the top to prevent excessive joint stress.

Common Mistakes to Avoid

• Flaring the elbows outward, which reduces triceps engagement and places strain on the shoulders.
• Using excessive weight, leading to improper form and risk of injury.
• Allowing the bar to move too far forward, which shifts tension away from the triceps.
• Rushing through the movement, reducing time under tension and effectiveness.
• Lifting the hips off the bench, which can cause instability and decrease focus on the triceps.

Benefits of Cable Lying Triceps Extensions

1. Enhanced Muscle Isolation: This exercise directly targets the triceps, making it an ideal choice for building strength and definition.

2. Constant Tension for Greater Muscle Activation: The cable system provides continuous resistance, ensuring the triceps remain engaged throughout the entire movement.

3. Reduced Joint Stress: Compared to barbell skull crushers, the cable variation places less strain on the elbows, making it a safer alternative for those with joint concerns.

4. Improves Lockout Strength: Strengthening the triceps enhances performance in pressing exercises like the bench press, shoulder press, and dips.

5. Versatile and Adjustable Resistance: The cable machine allows for easy weight adjustments, accommodating different strength levels and progression over time.
