01 Execution
How to do the Dumbbell Preacher Curl
Set up at a preacher bench with a single dumbbell ready and the seat adjusted so the armpit sits at the top of the pad.
Sit down and press the back of the upper arm flat against the angled pad, gripping the dumbbell with the palm up.
Let the arm extend almost fully at the bottom but stop just shy of full lockout to keep tension on the biceps.
Curl the dumbbell up by bending only at the elbow, keeping the upper arm glued to the pad.
Squeeze the biceps hard at the top with the dumbbell near shoulder height, pausing briefly.
Lower the dumbbell under control over 2 to 3 seconds back to the near-extended start position.
02 The payoff
Why it earns its spot
Builds the lower portion of the biceps through strict elbow isolation.
Removes momentum and shoulder swing from the curl entirely.
Trains each arm independently, fixing left-right strength imbalances.
03 Don't do this
Common mistakes
Lifting the upper arm off the pad mid-rep, which kills the strict isolation the bench enforces.
Locking the elbow fully at the bottom under load, which strains the joint and removes muscle tension.
Dropping the dumbbell back down quickly, missing the lower-biceps stretch where most of the growth lives.
Loading too heavy, which forces the pad-arm to lift and turns the curl into a swinging cheat rep.
