Alternating Double Dumbbell Seated Hammer Curl

Instructions for proper form

1. Sit on a flat bench with your feet flat on the ground and a dumbbell in each hand, arms fully extended down at your sides. 2. Keep your back straight and shoulders relaxed. 3. Begin the curl by flexing your elbow and bringing one dumbbell up towards your shoulder, while keeping the other arm extended down. 4. Maintain a neutral grip with palms facing inward. 5. Squeeze your bicep at the top of the movement, then slowly lower the dumbbell back to the starting position. 6. Alternate arms for each repetition, ensuring you maintain control and proper posture throughout the exercise.

Common mistakes to avoid

1. Using momentum to lift the weights rather than relying on the biceps. 2. Arching the back or leaning forward which can strain your back. 3. Letting the elbows drift away from the body, which reduces the effectiveness of the curl. 4. Not controlling the weight during the lowering phase, which can lead to injury.
