Incline DB Curl
Also known as: incline db curl, incline bicep curl, seated incline curl
Lie back on an incline bench with your arms hanging behind your torso and the biceps start every curl from a deep stretch — that is the whole argument for the incline dumbbell curl. The long head of the biceps crosses the shoulder joint, so this position lengthens it more than any standing curl can, and stretched-position training is strongly linked with growth. Expect to use noticeably less weight and feel noticeably more from it.
How to do the incline db curl, step by step
- Set a bench to roughly 45–60 degrees and sit back with a dumbbell in each hand.
- Let your arms hang straight down and slightly behind your torso, palms facing forward.
- Press your head and upper back into the pad and keep your shoulders down.
- Curl both dumbbells up without letting your elbows drift forward, keeping the upper arms hanging vertically.
- Stop when the biceps are fully contracted — the dumbbells will finish lower than in a standing curl, and that is correct.
- Lower for three seconds to a complete stretch at the bottom before the next rep.
Form cues that fix most reps
The stretch at the bottom is the point of the exercise — never cut it short to squeeze out extra reps.
Keep the shoulders pinned back against the bench; letting them roll forward erases the stretched position.
Take about 60–70 percent of your standing curl weight and expect it to feel harder.

Incline DB Curl sets and reps
Match the rep range to your goal, not the other way around. These are the standard evidence-based ranges:
| Goal | Sets × Reps | Rest |
|---|---|---|
| Strength | 3–5 × 3–6 | 2–3 min |
| Muscle growth | 3–4 × 8–12 | 60–90 sec |
| Endurance | 2–3 × 15–20 | 30–60 sec |

Incline DB Curl FAQ
What muscles does the incline dumbbell curl work?
It targets the biceps brachii with particular emphasis on the long head, which is stretched over the shoulder in the incline position. The brachialis and forearm flexors assist as in any curl.
Why is the incline curl so much harder than a standing curl?
The arm hanging behind the torso puts the biceps at a longer length, where it produces less force, and the strict bench position removes all body English. That combination is exactly why it works — the muscle does everything with no help. Drop the weight, keep the stretch, and treat the difficulty as the feature.
How many sets and reps should I do?
Three sets of 8–12 slow reps is plenty. Because the stretched position is demanding on the biceps tendon, add load gradually and prioritize a controlled three-second lowering phase over heavier dumbbells.
