The Seated Dumbbell Curl primarily targets the biceps, with no listed secondary muscles in the dataset. It's classified as a beginner-level strength movement using dumbbell.

What are the most common Seated Dumbbell Curl mistakes?

How should I program the Seated Dumbbell Curl — sets, reps and frequency?

As a single-joint isolation exercise, it responds well to a higher 10-15 reps for 2-4 sets, usually taken close to muscular failure. It tolerates higher frequency than a heavy compound lift — twice a week for the same muscle group is common. Add small amounts of weight or an extra rep once every working set can be completed with good form — the same progressive overload principle behind every strength exercise in the library.

How to do the Seated Dumbbell Curl, step by step:

  1. Step 1. Sit on a flat bench with a dumbbell on each hand being held at arms length. The elbows should be close to the torso.
  2. Step 2. Rotate the palms of the hands so that they are facing your torso. This will be your starting position.
  3. Step 3. While holding the upper arm stationary, curl the weights and start twisting the wrists once the dumbbells pass your thighs so that the palms of your hands face forward at the end of the movement. Make sure that you contract the biceps as you breathe out and make sure that only the forearms move. Continue the movement until your biceps are fully contracted and the dumbbells are at shoulder level. Hold the contracted position for a second as you squeeze the biceps.
  4. Step 4. Slowly begin to bring the dumbbells back to the starting position as your breathe in and as you rotate the wrists back to a neutral grip.
  5. Step 5. Repeat for the recommended amount of repetitions.
