How to do barbell incline triceps extension
Master the setup, range of motion, and tempo for safer, more effective reps.
Overview
This exercise is a variation of the 'Skull Crusher' performed on an incline bench. By tilting the bench, you put the long head of the triceps (the biggest part of the arm) under a massive stretch.
Because the long head of the tricep attaches to the shoulder blade, the incline angle stretches it more than a flat bench does. This leads to more muscle damage and, ultimately, more growth. It’s a pure isolation move, so don't worry about the weight—focus on the 'burn' and the stretch.
Why Use It
- Targets the 'long head' of the triceps for maximum arm thickness.
- Provides a greater stretch than flat or decline variations.
- Easy to track progress with small weight increments.
When to Use It
Use this toward the end of your workout as an isolation finisher. It works best in the 10-15 rep range.
Instructions for Proper Form
Setup
- The Bench: Set to a 30-45 degree incline.
- The Grip: Use a narrow, overhand grip on an EZ-bar or barbell.
- The Start: Lie back and hold the bar directly above your shoulders.
Execution
- The Lowering: Keep your upper arms fixed in place. Bend your elbows to lower the bar behind your head toward the bench.
- The Stretch: Go as low as your flexibility allows to feel a deep stretch in the back of your arms.
- The Extension: Use your triceps to push the bar back to the starting position. Do not let your upper arms swing forward.
Pro Tip: To keep constant tension on the triceps, don't bring the bar all the way back to 'vertical' at the top. Stop just short of it so the triceps have to keep working to hold the weight.
Common Mistakes
- Flaring Elbows: Letting your elbows point out to the sides takes the focus off the triceps and puts it on the shoulders.
- Moving the Shoulders: If your upper arm moves back and forth, you're using your lats to 'pullover' the weight instead of using your triceps.
- Hitting the Forehead: On an incline, the bar should go behind your head, not to your forehead.
Mistakes by Level
Beginner
- Using too much weight and turning it into a press.
- Losing control of the bar on the way down.
Intermediate
- Not getting a full stretch at the bottom.
- Flaring the elbows out as the muscle tires.
Advanced
- Moving the upper arms to involve the lats.
- Rushing the eccentric (lowering) phase.

Setup Requirements
- Set a bench to a 30-45 degree incline.
- Use an EZ-Bar if possible to save your wrists, or a standard barbell with a narrow grip.
- Lie back and hold the bar straight up over your chest.
Form Checklist
- Are my elbows pointing at the ceiling or flaring out?
- Is my upper arm moving back and forth, or staying still?
- Am I feeling the stretch in my triceps?
Range of Motion
Lower the bar by bending only at the elbows until it is behind your head. Extend back to the start position.
Breathing Pattern
Inhale as you lower the bar; exhale as you straighten your arms.
Tempo Guidance
3 seconds down, 1 second stretch at the bottom, 1 second up.
Caution Notes
- If you have 'golfer's elbow' or 'tennis elbow,' be very careful with this move. Start light.
Programming
Treat these guidelines as practical programming defaults, then scale load, volume, and frequency to match the rest of the training week.
Best For
- Tricep hypertrophy (long head).
- Improving arm definition.
- Building overhead stability.
Goal Tags
Rep Ranges
- 10-12 reps for growth.
- 12-15+ reps for a finisher.
Set Guidance
2-3 sets.
Rest Guidance
60-90 seconds.
Frequency
2 times per week.
Pairings
- Pair with bicep curls.
- Follow up with cable pushdowns to finish the muscle off.
Audience Notes
- Intermediate lifters will love the stretch this provides. Use an EZ-bar to make it more comfortable for the wrists.
Substitution Targets
Variations
Use progressions to increase difficulty when you master the movement, and regressions if you struggle with proper form or face mobility limitations.
Regressions
Cable Overhead Extension
Provides constant tension and is easier on the joints.
Best for: People with elbow pain.
Progressions
Dumbbell Incline Extension
Forces each arm to work independently.
Best for: Fixing arm size imbalances.
FAQ
Common Questions
Should I use a straight bar or EZ-bar?
The EZ-bar is usually much more comfortable for the wrists and elbows on this specific movement.
Where should I feel this?
You should feel a deep stretch and 'burn' in the back of your upper arm.
