Dumbbell Seated Curl
- Intermediate
- Isolation
- Rep-based
- Upper arms
The seated dumbbell curl is a foundational isolation exercise that targets the biceps brachii while minimizing momentum from the lower body. By performing the movement seated, you create a stable base that forces the biceps to handle the entire load through a full range of motion.

Setup
- Sit at the edge of a flat bench with your feet planted firmly on the floor for stability.
- Hold a dumbbell in each hand with an underhand (supinated) grip, palms facing forward.
- Position your arms fully extended at your sides with your shoulders retracted and chest up.
How to do it
- Exhale and curl the dumbbells toward your shoulders by flexing at the elbows, keeping your upper arms pinned to your torso.
- At the top of the movement, squeeze your biceps hard and rotate your pinkies slightly toward your shoulders to maximize the peak contraction.
- Inhale as you slowly lower the weights back to the starting position using a controlled 3-second tempo.
- Fully extend your arms at the bottom of each rep before beginning the next repetition.
Form checklist
- Keep your elbows stationary and tucked against your ribs throughout the entire movement.
- Avoid leaning back or swinging your torso to help lift the weights.
- Maintain a neutral wrist position; do not let your wrists curl excessively toward your forearms.
- Ensure your feet remain flat on the ground to maintain a stable center of gravity.
Pro tips
- Focus on the 'pinky-up' cue: as you reach the top of the curl, try to turn your pinky finger higher than your thumb to fully engage the short head of the bicep.
- Visualize your elbow as a fixed hinge that cannot move forward or backward, only rotate.
Make it harder
- Add a 2-second isometric hold at the midpoint (90-degree elbow flexion) of every rep.
- Perform '1.5 reps' by curling all the way up, lowering halfway down, curling back to the top, and then lowering fully.
