Dumbbell Hammer Curl
Arms · Dumbbell · Beginner
How to do it
- Stand up straight with a dumbbell in each hand, palms facing your torso.
- Keep your elbows close to your torso and rotate the palms of your hands until they are facing forward.
- This will be your starting position.
- Now, keeping the upper arms stationary, exhale and curl the weights while contracting your biceps.
- Continue to raise the weights until your biceps are fully contracted and the dumbbells are at shoulder level.
- Hold the contracted position for a brief pause as you squeeze your biceps.
- Then, inhale and slowly begin to lower the dumbbells back to the starting position.
- Repeat for the recommended amount of repetitions.

Sets and reps
Use an easy load and stop well before failure while you learn the movement.
Finish most sets with 1-3 good reps still available.
Use strict form and progress the load only after the top of the rep range is clean.
Common mistakes
- Rushing the weaker side or letting the dumbbells drift. Keep both sides moving through the same range and tempo.
- Shortening the range as fatigue builds. Use the largest pain-free range that keeps tension on your biceps.
- Turning the set into a speed contest. Pause briefly in the hardest position, then control the return instead of dropping into the next rep.
