How to Preacher Hammer Dumbbell Curl

  1. 1

    Place the upper part of both arms on top of the preacher bench as you hold a dumbbell in each hand with the palms facing each other (neutral grip).

  2. 2

    As you breathe in, slowly lower the dumbbells until your upper arm is extended and the biceps is fully stretched.

  3. 3

    As you exhale, use the biceps to curl the weight up until your biceps is fully contracted and the dumbbells are at shoulder height.

  4. 4

    Squeeze the biceps hard for a second at the contracted position and repeat for the recommended amount of repetitions.

Common Mistakes

  • • Focus on the mind-muscle connection — feel the target muscle working through each rep.
  • • Use a controlled tempo of 2 seconds up, 2 seconds down to eliminate momentum.
  • • Start with your weaker side first — match the reps on your stronger side to prevent imbalances.
  • • Squeeze at peak contraction for a full second — this is where most of the growth stimulus occurs.
