How to do barbell lying triceps extension
Master the setup, range of motion, and tempo for safer, more effective reps.
Overview
This exercise is a staple for anyone looking to grow their triceps. By lying on a bench and lowering a bar toward your forehead, you place the triceps under a massive stretch. Unlike a standard press, this movement isolates the elbow joint, meaning your arms do all the heavy lifting without much help from your chest or shoulders.
It is best used as a 'follow-up' exercise after you've finished your heavy pressing for the day. Because it puts a lot of tension on the elbow, focus on smooth, controlled reps rather than trying to move the heaviest weight possible.
Why Use It
- Directly targets all three heads of the triceps for maximum arm growth.
- Improves lockout strength for bigger lifts like the bench press and overhead press.
- Provides a deep stretch that is difficult to achieve with cables or machines.
When to Use It
Perform this after your main compound lifts (like bench press). It works best in the middle of your workout when your joints are warm but your arms still have enough energy to handle a barbell.
Instructions for Proper Form
Setup
- The Grip: Lie on the bench and hold the barbell with an overhand grip, hands about shoulder-width apart.
- The Start: Press the bar straight up so it's over your chest.
- The Angle: Slightly tilt your arms back toward your head so they aren't perfectly vertical. This keeps the triceps working even at the top.
Execution
- The Descent: Slowly bend your elbows to lower the bar toward your forehead.
- Keep your upper arms frozen in place; only your forearms should move.
- The Bottom: Stop when the bar is an inch from your forehead or the top of your head.
- The Extension: Use your triceps to push the bar back to the starting position.
- Focus on 'unfolding' your arms rather than just pushing the weight up.
Pro Tip: Imagine there is a rod running through both of your elbows, pinning them in place. They shouldn't move forward or backward as you lower the weight.
Common Mistakes
- Elbow Flaring: Letting your elbows point out to the sides. This shifts the work to your chest and shoulders.
- Moving the Shoulders: Turning the move into a 'pullover' by swinging your upper arms. Keep those upper arms still!
- Wrist Collapse: Letting the weight of the bar bend your wrists back. Keep them 'punched' toward the ceiling.
Mistakes by Level
Beginner
- Going too heavy and losing control of the bar path.
- Banging the bar into the forehead (go slow!).
Intermediate
- Using momentum to 'bounce' out of the bottom position.
- Letting the elbows flare out as the set gets hard.
Advanced
- Shortening the range of motion to use more weight.
- Losing the 'stretch' at the bottom by rushing the rep.

Setup Requirements
- Lie flat on a bench with your feet pressed firmly into the floor.
- Hold the barbell with a shoulder-width grip directly over your chest.
- Pinch your shoulder blades together to create a stable base against the bench.
Form Checklist
- Are your elbows staying tucked in rather than flaring out?
- Is your upper arm staying vertical or slightly angled back?
- Are your wrists staying straight and strong?
- Is the bar moving in a smooth arc?
Range of Motion
Lower the bar until it is just above your forehead or slightly behind the top of your head, then extend back to the start without locking the elbows out aggressively.
Breathing Pattern
Take a breath in as you lower the bar toward your head; exhale forcefully as you push the bar back up.
Tempo Guidance
Use a 3-second descent to feel the stretch, a tiny pause at the bottom, and a 1-second drive up.
Caution Notes
- If you feel 'stinging' in your elbows, try lowering the bar slightly behind your head instead of to your forehead, or switch to an EZ-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
- Building muscle size (hypertrophy) in the arms.
- Isolating the triceps without chest fatigue.
- Improving elbow extension strength.
Goal Tags
Rep Ranges
- 8-12 reps for muscle growth.
- 12-15 reps for better mind-muscle connection and joint health.
Set Guidance
3-4 sets is usually plenty to fatigue the triceps.
Rest Guidance
60-90 seconds. You want your triceps to recover, but you want to keep the 'pump' in the muscle.
Frequency
1-2 times per week as part of a push or arm-focused session.
Pairings
- Pair with a bicep curl for an 'antagonist' superset.
- Follow up with cable pressdowns to completely finish the muscle.
Audience Notes
- Beginners should start very light to master the 'arc' of the movement.
- Advanced lifters can angle the upper arms back 15 degrees to keep constant tension on the triceps.
Substitution Targets
- Dumbbell Lying Triceps Extension
- EZ-Bar 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
Dumbbell Skull Crushers
Dumbbells allow for a more natural wrist position and help find a comfortable path for the elbows.
Best for: Lifters with cranky elbows or wrist issues.
Progressions
Incline Barbell Extension
Doing this on an incline bench increases the stretch on the long head of the triceps.
Best for: Advanced hypertrophy goals.
FAQ
Common Questions
Does this exercise hurt the elbows?
It can if done with poor form or too much weight. Ensure your elbows stay tucked and the movement is controlled. If pain persists, try using an EZ-bar or dumbbells.
Should the bar touch my forehead?
It doesn't have to. Bringing it to within an inch of your forehead or slightly behind your head is perfect for keeping tension on the muscle.
