Dumbbell Alternate Bicep Curl
Dumbbell Alternate Bicep Curl is a beginner-level isolation in the strength category that primarily works the biceps. It also recruits the forearms. It is performed with dumbbells.


How to do it
- 1Stand (torso upright) with a dumbbell in each hand held at arms length. The elbows should be close to the torso and the palms of your hand should be facing your thighs.
- 2While holding the upper arm stationary, curl the right weight as you rotate the palm of the hands until they are facing forward. At this point continue contracting the biceps as you breathe out until your biceps is fully contracted and the dumbbells are at shoulder level. Hold the contracted position for a second as you squeeze the biceps. Tip: Only the forearms should move.
- 3Slowly begin to bring the dumbbell back to the starting position as your breathe in. Tip: Remember to twist the palms back to the starting position (facing your thighs) as you come down.
- 4Repeat the movement with the left hand. This equals one repetition.
- 5Continue alternating in this manner for the recommended amount of repetitions.

Tips and common mistakes
- •Focus on the muscle contraction and control the eccentric (lowering) phase.
- •Add load only once you complete all reps with good form — progressive overload.
- •Initiate the pull from the target muscle rather than jerking with body momentum.
- •Prioritize full range of motion over heavy weight with partial reps.
Sets and reps
For hypertrophy: 3–4 sets × 8–12 reps with 1–2 reps in reserve (RPE 7–9) and 1–2 minutes rest. For strength: 3–5 × 4–6 with longer rest.
