How to Do Hammer Bicep Curls
Hammer bicep curls target the outer head of the biceps and the outside of the forearm. Since hammer curls use dumbbells, they isolate the biceps and work each arm equally hard during the exercise.

Lower your arms slowly, keeping your elbows are next to your torso to place the emphasis on your biceps.

5
Complete 12 to 15 repetitions of the hammer bicep curl. If you can't do at least 8 reps, lower the weight. If you can comfortably complete 15 reps, increase the weight for your next set or workout. Complete 3 to 4 sets.

Tips & Warnings
Engage your abdominal muscles before lifting the dumbbells when you do a hammer bicep curl.
You can either work both arms at once or focus on one arm at a time.
The hammer bicep curl is performed with a neutral wrist position, so any weakness in your wrist has little effect on the number of repetitions or amount of weight you can lift.
If you're lifting heavy weights, have a spotter stand in front of you.
Leaning back during the bicep hammer curl causes your body weight and momentum to lift the weights rather than your biceps. Leaning back can also hurt your lower back, especially when you're using heavy weights.
