1
Sit on a flat bench with feet firmly planted on the floor, back against the backrest, torso upright and stable. Hold a dumbbell in each hand with arms fully extended downward at the sides, palms facing forward in a supinated grip position.
2
Maintain an upright seated posture with shoulders back and core engaged. Position the dumbbells with neutral grip at arm's length, ensuring elbows remain close to the sides of the torso throughout the movement.
3
Lower the dumbbells in a controlled manner by extending the elbows, allowing the weights to descend toward the floor while keeping the upper arms stationary. The forearms should move through a full range of motion until slight tension is felt at full extension, maintaining constant tension throughout the descent.
4
Curl the dumbbells upward by flexing the elbows, bringing the weights toward shoulder height while keeping upper arms fixed against the body. Squeeze the biceps at the top of the movement, then return to the starting position in a controlled manner to complete one repetition.
