A curl performed with both arms braced on a preacher bench, eliminating swing so the dumbbells isolate the biceps through a full stretch.

Equipment

Dumbbell

Pattern

Elbow flexion

Setup

  1. 01Adjust the seat so armpits sit atop the pad.
  2. 02Rest both upper arms flat on the pad.
  3. 03Hold a dumbbell in each hand, palms up.
  4. 04Start with elbows almost fully extended.

Execution

  1. 01Curl both dumbbells toward the shoulders.
  2. 02Keep the upper arms pressed into the pad.
  3. 03Squeeze the biceps at the top.
  4. 04Lower slowly to a deep, controlled stretch.

Checkpoints

  • -Triceps stay in contact with the pad every rep.
  • -The bottom position reaches near-full elbow extension.
  • -Shoulders stay down, not shrugging toward the ears.
  • -Wrists stay straight under the dumbbells.

Common mistakes

  • -Lifting the elbows off the pad at the top.
  • -Dropping into the stretch instead of lowering under control.
  • -Cutting the bottom range to protect the ego load.
  • -Leaning back off the seat to finish grinding reps.

Programming notes

  • -Use 3 sets of 8 to 12 reps.
  • -Take 3 seconds down; the stretched position drives growth.
  • -Progress carefully; the bottom position is the injury-prone range.
