1
Lie prone (face down) on the floor or elevated surface with body straight and aligned. Position legs extended with feet together or slightly apart for stability. Keep torso flat against the ground.
2
Hold a dumbbell in each hand with arms extended forward at shoulder width, palms facing upward (supinated grip). Ensure elbows are slightly bent and positioned close to the body throughout the movement.
3
Lower the dumbbells by extending the elbows, allowing the arms to straighten while maintaining a slight bend. Control the descent by resisting gravity, ensuring the biceps lengthen in a controlled eccentric contraction.
4
Curl the dumbbells upward by flexing at the elbow joint, bringing the weights toward the shoulders while maintaining the prone position. Squeeze the biceps at the top and return to the starting extended position with control.
