How to do dumbbell incline two arm triceps extension
Master the setup, range of motion, and tempo for safer, more effective reps.
Overview
By lying on an incline, you change the angle of the pull. This puts the triceps in a deep stretch at the bottom of every rep. Using two dumbbells instead of one forces each arm to carry its own weight, preventing your stronger side from helping out. This builds balanced strength and a more symmetrical look.
Why Use It
- Targets the long head of the triceps through a deep stretch.
- Forces both arms to work independently to fix strength gaps.
- Increases the time your muscles spend under tension compared to flat variations.
When to Use It
Add this to your routine when you want to focus on arm shape and symmetry after your main pressing movements.
Instructions for Proper Form
Setup
- Bench Angle: Set your bench to a 45-degree incline.
- Get Set: Sit back with a dumbbell in each hand. Press them straight up over your chest.
Execution
- The Descent: Bend your elbows to lower the weights toward your shoulders. Keep your upper arms frozen in space.
Pro Tip: Imagine your upper arms are bolted to the ceiling; only your forearms should move.
- The Extension: Drive the weights back up by straightening your arms. Squeeze the back of your arms hard at the top.
Coaching Cues
- Point your elbows at the ceiling
- Lower the weights like you're scratching your back
- Move both hands at the exact same speed
Common Mistakes
- Elbow Flaring: Letting the elbows point out to the sides, which shifts the work to your shoulders.
- Arching the Back: Lifting the ribcage and arching the spine to help move the weight.
- Rushing the Bottom: Bouncing the weights out of the stretch position instead of controlling them.
How to Fix It
- Elbow Flaring: Imagine you are trying to keep your elbows tucked inside a narrow hallway.
- Arching the Back: Brace your abs and keep your lower back glued to the bench pad.
- Rushing the Bottom: Pause for a one-second count at the deepest part of the stretch before pressing up.

Form Checklist
- Are your elbows staying narrow?
- Is your lower back pressed into the bench?
- Are the weights moving in a smooth, controlled arc?
Range of Motion
Lower the weights until they are beside your ears. Extend fully until the arms are straight.
Breathing Pattern
Inhale as you lower the weights; exhale as you drive them back up.
Tempo Guidance
3-1-1-0: 3 seconds down, 1 second stretch, 1 second up.
Caution Notes
- Start with lighter weights than you use for flat bench extensions to protect the elbow joint.
Programming
Treat these guidelines as practical programming defaults, then scale load, volume, and frequency to match the rest of the training week.

FAQ
Common Questions
Can I do this with one dumbbell?
You can, but using two dumbbells is better for identifying strength gaps between your left and right sides.
