Before the first rep
How to set up
- 01
Set the bench. Set an adjustable bench to about 45 degrees. If that pulls hard on the front of your shoulders, raise it a notch or two.
- 02
Pick lighter dumbbells. Choose dumbbells noticeably lighter than you use for standing curls. The stretched bottom position makes the same weight feel heavier.
- 03
Sit back. Sit with your hips at the back of the seat and your upper back and head resting on the pad. Plant your feet flat on the floor.
- 04
Let the arms hang. Let your arms hang straight down toward the floor from your shoulders, palms facing forward, so your elbows sit slightly behind your torso.
- 05
Shoulders back. Pull your shoulders back and down into the pad before the first rep, and keep them there.
Step by step
How to do the incline dumbbell curl
- 01
Start from the stretch. Begin with your arms straight and hanging, palms forward. You should feel a light stretch along the front of your upper arm.
- 02
Curl. Bend your elbows and bring the dumbbells up toward your shoulders. Your elbows stay pointing at the floor; only your forearms move.
- 03
Stop at the top. Curl until the dumbbells are in front of your shoulders and your elbows are as bent as they go without moving forward. Squeeze your biceps for a moment.
- 04
Lower slowly. Take two to three seconds to lower the dumbbells along the same path, keeping your palms facing forward.
- 05
Finish at full stretch. Straighten your arms fully at the bottom without bouncing, pause briefly in the stretch, then start the next rep.
Cues to say in your head

- Back stays on pad
- Palms face forward
- Slow to the stretch
- Pause at the bottom
Fix these first
Common mistakes
Elbows drifting forward as you curl
Keep your elbows pointing at the floor and end the rep just before they would move. Swinging the elbows forward turns part of the rep into a front raise.
Lifting your head and shoulders off the pad
Keep your upper back and head on the bench. Sitting up shortens the stretch and lets you swing the weight.
Cutting the bottom short
Lower all the way until your arms are straight. The stretched bottom is the reason to choose this curl over a standing one.
Dropping into the bottom
Lower under control and pause instead of letting the dumbbells fall and bounce out of the stretch.
Going too heavy
Use a weight you can control for every rep with a full range. If you have to swing or shorten reps, go lighter.
Wrists curling in at the top
Keep your wrists straight and in line with your forearms for the whole rep, so the bend comes from your elbows.
Stay safe
Start lighter than you think, because the stretched bottom position can load the front of the elbow and shoulder more than a standing curl. To end a set or fail a rep, lower the dumbbells under control to your sides, then set them on the floor beside the bench rather than letting them drop. If you feel a pinch at the front of your shoulder, raise the bench angle. Stop and get it checked if you feel sharp pain at the front of the elbow or upper arm, or a pop or sudden weakness while curling.
Programming
Sets, reps and how much weight
| Goal | Sets | Reps | Load | Rest |
|---|---|---|---|---|
| Muscle | 3 to 4 | 8 to 12 | 60–75% 1RM | 1 to 2 min |
| Endurance | 2 to 3 | 12 to 20 | 50–62% 1RM | 45 to 90 s |
| Technique | 2 to 3 | 10 to 12 | 45–60% 1RM | 1 to 1.5 min |
Plan your next session
Put in a recent set. You get working weights for your goal, a warm-up and the plates to load.
Estimated 1RM 216 lb
Endurance sets
108–134lb
2 to 3 sets of 12 to 20 reps, 45 to 90 s rest. Lighter dumbbells and steady reps. A good finisher at the end of an arm or pull day.
Estimates use the Epley formula and work best from sets of 3 to 8 reps. Treat them as a starting point and adjust by how the first working set moves.
Questions
Incline Dumbbell Curl questions
What muscles does the incline dumbbell curl work?
Mainly the biceps, with the brachialis underneath and the brachioradialis and forearms helping bend the elbow. Your front delts and upper back hold your arm and shoulders still against the bench.
Does the incline curl work the long head of the biceps?
Coaches often use it for the long head, because the incline puts your arm behind your body and stretches that part of the biceps. Treat that as a coaching emphasis rather than isolation: the whole biceps does the work.
What angle should the bench be for incline curls?
About 45 degrees suits most people. If you feel a strong pull or pinch at the front of your shoulders, raise the bench a notch or two until the stretch feels comfortable.
Why can I curl less weight on an incline?
Starting from a full stretch with your arms behind your body usually makes the bottom of the rep harder, and the bench stops you from using your body to swing the weight. Expect to use lighter dumbbells than on standing curls.
How many sets and reps of incline dumbbell curls should I do?
For muscle growth, 3 to 4 sets of 8 to 12 reps works well, taken close to failure with a full stretch on every rep. It usually comes after heavier pulling or curling work.
Should I curl both arms together or alternate?
Either works. Curling both together saves time; alternating lets you focus on one arm at a time, as long as your back stays on the pad.
