The seated dumbbell bicep curl removes lower body momentum from the equation, forcing your biceps to do every bit of the work with zero shortcuts. Master this movement and you build the kind of dense, functional arm strength that carries over to every pull you perform.
Sit tall on a bench with a dumbbell in each hand, arms fully extended, palms facing forward and elbows pinned against your torso.
Curl both dumbbells upward in a smooth arc, squeezing the biceps hard as the weights approach shoulder height.
Pause at peak contraction for one count, ensuring your upper arms stay completely vertical and stationary.
Lower the dumbbells under full control back to the starting position, resisting gravity all the way to full elbow extension.
Common mistakes
Swinging the torso back at the start of each rep to gain momentum — brace your core and initiate the movement purely from the elbow joint.
Letting the elbows drift forward as the weight rises, which shifts load onto the front delts — keep elbows anchored at your sides throughout the entire curl.
Dropping the weight too fast on the descent and losing the eccentric phase — the lowering portion builds as much muscle as the lift, so take at least two seconds coming down.
Pro tip — Actively supinate your wrists outward as you curl, rotating the pinky side of your hand toward the ceiling at the top, to maximize bicep peak contraction beyond what a standard curl achieves.
