1
Sit upright on an adjustable weight bench set to approximately 45-60 degrees incline, feet firmly planted on the floor, back and head supported against the backrest for stability
2
Grasp dumbbells with a neutral grip (palms facing each other) or supinated grip (palms facing forward), arms hanging naturally at sides with elbows positioned slightly in front of torso to maintain constant tension
3
Lower the dumbbells in a controlled manner by extending the elbows, allowing the weight to descend in an arc while maintaining a slight bend at the bottom to prevent joint strain, resisting the downward pull of gravity
4
Flex the elbows and curl the dumbbells upward in a controlled arc, bringing palms toward shoulders while keeping upper arms relatively stationary, squeeze biceps at the peak contraction, then return to starting position
