1
Sit on a weight bench with back support, feet flat on floor. Hold a dumbbell in each hand with arms extended downward at sides, palms facing forward. Maintain upright posture with shoulders back and core engaged.
2
Position dumbbells with neutral grip at thigh level. Ensure elbows remain stationary and close to the torso throughout the movement. Keep wrists neutral and maintain a firm grip on the dumbbells.
3
Lower the dumbbells in a controlled manner by extending the elbows, allowing the weights to descend toward the floor while maintaining arm positioning. The eccentric phase should last 2-3 seconds, resisting gravity rather than simply dropping the weight.
4
Curl the dumbbells upward by flexing the elbows, raising the weights toward the shoulders. Keep elbows locked in position and avoid swinging. Squeeze the biceps at the top of the movement, then return to starting position in a controlled manner.
