Dumbbell Incline Curl
The incline dumbbell curl is a biceps curl performed lying back on an incline bench, arms hanging behind the torso, to load the biceps in its most stretched position.

How it is executed
- Lie back on an incline bench with dumbbells in your hands, arms hanging straight down.
- Curl the weights up without moving your shoulders.
- Pause at the top, then lower slowly until your arms are fully extended.
Common mistakes
- Letting the elbow drift forward on the way up. The incline exists precisely to keep the arm behind you, so drifting forward gives away the stretch you set up for. Keep the upper arm hanging behind your torso the whole set.
- Coming off the backrest and helping with the torso on the last reps. Keep shoulders and head on the bench and end the set when you can no longer curl without moving.
- Cutting the lowering short because the stretch feels uncomfortable. The stretched position is the point of this variation. Pick a load that lets you reach full elbow extension under control.
- Dropping the bench almost flat chasing more stretch. Past a certain angle the tension moves to the shoulder. Somewhere between 45 and 60 degrees is enough.
Frequently asked questions
- Which part of the biceps does the incline curl work?
- It works both heads of the biceps, but the arm hanging behind the torso puts the most tension on the long head, which crosses the shoulder and stretches more in that position. The brachialis and brachioradialis assist elbow flexion. That is why this curl feels different from the standing version: the load comes in from the stretched position.
- What angle should the bench be set to for incline curls?
- Somewhere between 45 and 60 degrees is the usual range. More upright resembles a seated curl and loses the stretch; flatter pushes the shoulder into a strained position and the biceps stops being the limiting factor. If it is your first time, start near 60 degrees and lower the backrest as your shoulder gets comfortable with the arm hanging.
- Incline curl or standing curl: which one is better?
- The standing curl allows more load and is the better choice for accumulating volume with a bar or dumbbells. The incline curl uses less weight but loads the biceps in its stretched position, which the standing curl barely touches. Many coaches program both in the same week: a heavy standing curl and an incline curl with more reps and a slow lowering phase.
- What is the difference between the incline curl and the Bayesian curl?
- Both aim for the same thing: working the biceps with the arm behind the torso. The incline curl does it with dumbbells, where tension drops near the top of the rep because gravity stops pulling against you. The Bayesian curl uses a low cable behind you, which keeps tension constant through the whole arc, including the stretched position. With a cable available, alternate the two; without one, the incline curl fills the same role.
