How to do dumbbell incline biceps curl
Master the setup, range of motion, and tempo for safer, more effective reps.
Overview
By leaning back, you remove the ability to swing your hips or use momentum. This forces the biceps to do 100% of the work. It specifically targets the long head of the muscle, which is responsible for the peak of the arm.
Why Use It
- Forces the biceps to work from a deep, stretched position.
- Eliminates cheating by fixing your torso against the bench.
- Targets the long head of the biceps to improve arm shape.
When to Use It
Perform this after your main pulling movements. It works best as a high-tension finisher to fully exhaust the arms.
Instructions for Proper Form
Setup
- Bench Angle: Set the bench to a 45-degree incline.
- The Seat: Sit back with your head and spine supported and let your arms hang straight down.
Execution
- The Curl: Pull the weights toward your shoulders while keeping your elbows pinned in space.
Pro Tip: Imagine your elbows are heavy anchors pointing straight at the floor; do not let them drift forward.
- The Stretch: Lower the weights slowly until your arms are completely straight.
Coaching Cues
- Anchor your elbows to the floor
- Squeeze your triceps at the bottom
- Keep your head on the headrest
Common Mistakes
- Swinging the Elbows: Letting the elbows move forward as you curl, which uses the shoulders instead of the arms.
- Short-Changing the Rep: Stopping the movement before the arms are fully straight at the bottom.
- Peeling the Head Off: Lifting your head off the bench to watch your arms, which puts unnecessary strain on your neck.
How to Fix It
- Swinging the Elbows: Keep your elbows tucked into your sides and imagine they are bolted to the bench frame.
- Short-Changing the Rep: Make sure the dumbbells pass your hips on every single repetition.
- Peeling the Head Off: Pick a spot on the ceiling and keep your eyes locked on it throughout the set.

FAQ
Common Questions
Why does this feel harder than standing curls?
The incline removes your ability to swing your hips and puts the muscle in a deeper stretch.
