Single Arm Dumbbell Incline Bench Preacher Curl

Difficulty level: Beginner

Target Muscle: Biceps

Equipment: Dumbbell

Instructions for proper form

Start by setting an incline bench at a 30-45 degree angle. Sit on the bench with your feet flat on the floor. Hold a dumbbell in one hand with a supinated grip (palm facing up) and rest that elbow on the incline bench. Ensure that your upper arm stays stationary as you curl the dumbbell towards your shoulder. Squeeze your bicep at the top of the movement, then lower the dumbbell back to the starting position in a controlled manner.

Common mistakes to avoid

Avoid using momentum to lift the dumbbell. Do not allow your elbow to leave the bench or your upper arm to move during the curl. Ensure that you do not arch your back; maintain a neutral spine throughout the exercise.
