How to do cable lying triceps extension(low)
Master the setup, range of motion, and tempo for safer, more effective reps.
Overview
The 'Low' version of the cable lying triceps extension typically refers to the pulley height or a specific bench angle that increases the stretch on the triceps. By pulling from a low point behind the head, you force the triceps to work from a fully lengthened position.
This is excellent for 'filling out' the back of the arms. Because the cable is pulling from behind you, there is significant tension even when your arms are fully bent, which is where most free-weight exercises lose their effectiveness.
Why Use It
- Maximum stretch on the triceps long head.
- Constant tension that free weights can't match.
- Safer for the elbows than heavy barbell variations.
When to Use It
Perfect as a second or third exercise in an arm workout. Use it to 'finish' the triceps after heavy compound pressing.
Instructions for Proper Form
Setup
- The Pulley: Set the cable to the lowest notch.
- The Bench: Place the bench so that when you lie down, your head is almost touching the machine.
- The Grip: Use a rope attachment for better range of motion. Reach back and grab the rope with a neutral grip.
Execution
- The Stretch: Start with your elbows bent and the rope behind your head. You should feel a deep stretch in your triceps.
- The Drive: Extend your arms toward the ceiling, pulling the rope ends apart slightly at the top for a better contraction.
- The Control: Slowly lower the rope back behind your head, resisting the pull of the cable.
Pro Tip: Keep your elbows tucked close to your ears to ensure the long head of the tricep is doing the heavy lifting.
Common Mistakes
- Arching the Back: This turns the move into a 'pullover' and uses the chest/back. Keep your core tight.
- Short-Changing the Rep: Not going deep enough into the stretch. The bottom of the rep is the most important part here.
- Flaring Elbows: Letting the elbows wing out wide, which puts stress on the shoulder joint.
Mistakes by Level
Beginner
- Using the back to swing the weight up.
- Not keeping the upper arms vertical.
Intermediate
- Rushing the eccentric (lowering) phase.
- Losing the 'squeeze' at the top.
Advanced
- Not using a heavy enough load to challenge the stretched position.

Stabilizers
- Core
- Shoulders
Setup Requirements
- Low pulley setting.
- Flat bench positioned so your head is very close to the weight stack.
- Rope or EZ-bar attachment.
Form Checklist
- Elbows should point straight up or slightly back.
- Keep the ribs tucked; don't arch the lower back.
- Ensure the cable path doesn't rub against the bench or your head.
Range of Motion
Lower the attachment behind your head as far as comfortably possible, then extend fully.
Breathing Pattern
Exhale on the way up; inhale on the way down.
Tempo Guidance
3 seconds down to emphasize the stretch, 1 second up.
Caution Notes
- Be careful when 'unracking' the weight from behind your head; it may be easier to have a partner hand you the bar.
Programming
Treat these guidelines as practical programming defaults, then scale load, volume, and frequency to match the rest of the training week.
Best For
- Targeting the long head of the triceps.
- Improving elbow health through controlled eccentric loading.
- Adding variety to arm days.
Goal Tags
Rep Ranges
- 12-15 reps for hypertrophy.
- 15-20 reps for metabolic stress.
Set Guidance
3 sets of 12-15 reps.
Rest Guidance
60 seconds.
Frequency
2 times per week.
Pairings
- Pair with Cable Hammer Curls.
- Superset with Close Grip Bench Press.
Audience Notes
- Ideal for intermediate lifters looking to break through an arm-growth plateau.
Substitution Targets
- Overhead Dumbbell Extension
- Barbell Skull Crusher
Variations
Use progressions to increase difficulty when you master the movement, and regressions if you struggle with proper form or face mobility limitations.
Regressions
Standing Cable Overhead Extension
Easier to set up and requires less core stability.
Best for: Learning the overhead tricep stretch.
Progressions
Incline Cable Tricep Extension
The incline angle increases the stretch even further.
Best for: Advanced arm development.
FAQ
Common Questions
Why use a rope instead of a bar?
A rope allows your wrists to move naturally and lets you pull the ends apart at the top, which can help you get a harder tricep contraction.
