Dumbbell Seated Triceps Extension

Sit on a bench with back support, feet flat on the floor.

Hold a dumbbell with both hands, palms facing upward, and lift it overhead until your arms are fully extended.

Use a weight that allows you to maintain proper form throughout the exercise.

Keep your core engaged to stabilize your body and prevent arching your back.

Lowering the dumbbell too far behind the head or arching the lower back to compensate for limited shoulder mobility.

Letting the elbows flare and swinging the torso instead of controlling elbow extension.
