This is strength training exercise for biceps.

1. Hold the dumbbells a bit far from yourself so that you can carry out more weight. This can be extremely good while you are performing exercises that strengthen the biceps. Now, you need to work on a normally inclined dumbbell curl, keeping your wrist as much back as you can so that you can easily neutralize any kind of stress or pressure that is positioned on them.
2. Sit on an inclined bench which should be angled 45 degrees when you are holding the dumbbells in each of your hands.
3. Hang your arms by your sides with the elbows and then turning your palms forward with your thumbs positioning away from rest of your body. Remember that you must be keeping this posture via you are performing this exercise and should not twist your hands. This is your starting position.
4. Exhale while your biceps are completely contracted. Do not swing your arms, and it is good to keep your arms under controlled motion and hold the contracted posture for a count of 3.
5. Slowly get back to the starting posture while you are inhaling.
6. Repeat these steps for the suggested amount of recurrence.
