Dumbbell Straight Arm Bicep Swing

How to do the Dumbbell Straight Arm Bicep Swing

1. 1Stand tall with your feet about hip-width apart, holding a single dumbbell in front of your thigh with a neutral or overhand grip.
2. 2Brace your core, set your shoulders down and back, and keep a soft bend in your knees.
3. 3Keeping your working arm completely straight, swing the dumbbell forward and up in a smooth arc, leading with the back of your hand.
4. 4Raise the dumbbell to roughly shoulder height, keeping the movement controlled rather than letting momentum take over.
5. 5Pause briefly at the top with the weight in front of your shoulder and your arm parallel to the floor.
6. 6Lower the dumbbell along the same path under control, resisting it back down to the starting position.
7. 7Complete your reps on one side, then switch the dumbbell to the other arm and repeat.
8. 8Set the dumbbell down safely when the set is finished.

Form tips

• Keep your elbow locked straight the whole rep so the front of the shoulder does the work rather than the arm bending.
• Use a weight you can swing with control to shoulder height, not one that forces you to heave with your back or legs.
• Keep your torso upright and core braced so the trunk stays still and the shoulder moves the load.
• Exhale as you raise the dumbbell and inhale as you lower it back down.

Common mistakes

• Swinging with body momentum from the hips and knees, which shifts the load off the shoulder and reduces the training effect.
• Bending the elbow on the way up, which turns it into an arm curl instead of a straight-arm shoulder movement.
• Raising the dumbbell far above shoulder height, which adds unnecessary strain on the shoulder joint.
• Dropping the weight back down without control, wasting the lowering phase and risking a jerk on the shoulder.
• Going too heavy and rounding or arching the back to launch the weight, which loads the spine instead of the target.
