How to do it

1. 1 Sit on the preacher bench in a way that your armpit is just touching the top of the sloped section.
2. 2 Hold the dumbbell in a way that your palm is facing up with your arm extended and your upper arm resting on the bench.
3. 3 Lift the dumbbell, keeping your upper arm on the bench until your elbow is fully bent, and slowly return to the starting position until your arm is fully straight.

Tips

• Your upper arm should rest on the bench throughout this exercise.
• Inhale as you lift the dumbbell and exhale as you lower it down.
• Keep your arms shoulder-width apart.
