How to perform One Arm Dumbbell Preacher Curl
  1. Grab a dumbbell with the right arm and place the upper arm on top of the preacher bench or the incline bench. The dumbbell should be held at shoulder length. This will be your starting position.
  2. As you breathe in, slowly lower the dumbbell until your upper arm is extended and the biceps is fully stretched.
  3. As you exhale, use the biceps to curl the weight up until your biceps is fully contracted and the dumbbell is at shoulder height. Again, remember that to ensure full contraction you need to bring that small finger higher than the thumb.
  4. Squeeze the biceps hard for a second at the contracted position and repeat for the recommended amount of repetitions.
  5. Switch arms and repeat the movement.

Why You Might Need a One Arm Dumbbell Preacher Curl Alternative

You may need substitutes because of elbow pain, no preacher bench, equipment limits, or to break plateaus. The preacher position shortens the biceps’ moment arm and reduces shoulder contribution; some lifters feel joint compression at the bottom. Alternatives let you alter ROM, change elbow angle to shift activation between the short and long heads, or remove bench pressure for rehab. When swapping, keep the upper arm stationary and avoid shoulder swing to preserve isolation. Use slower eccentrics to control torque on the elbow and preserve muscle tension while you adapt.

One Arm Dumbbell Preacher Curl FAQ

What muscles does One Arm Dumbbell Preacher Curl work?

The exercise isolates the elbow flexors: primarily the biceps brachii (short and long heads) and the brachialis, with secondary brachioradialis involvement. The preacher setup reduces shoulder extension, so the biceps take more of the load, keep the elbow fixed to maximize elbow-flexor activation.

Can I build muscle without doing One Arm Dumbbell Preacher Curl?

Yes. You can stimulate biceps growth with other curls and pulling movements that provide progressive overload and full ROM. Emphasize controlled eccentrics, proper supination, and gradual increases in load or reps to drive hypertrophy.
