Angle The Dumbbells for Proper DB Pressing
When performing a dumbbell bench press, the angle of the dumbbells should generally slightly angle inward, not held straight like a barbell. Here’s how and why…
Proper Dumbbell Angle:
Neutral to semi-supinated grip - Dumbbells should be angled at about 30-45 degrees, with palms facing slightly inwards rather than straight forward.
Think of the dumbbells forming a “V” shape at the bottom of the press, not being completely parallel to each other like a barbell.
Why Not Mimic Barbell Angle?
The main reason is anatomical alignment with the pectoral (chest) muscle fibers.
Pec Major Muscle Fiber Direction:
The sternal head (lower chest) fibers run horizontally and upward from the sternum to the humerus.
The clavicular head (upper chest) runs more diagonally downward from the clavicle to the humerus.
Overall, most pec fibers fan out from the center of the chest and insert on the upper arm in a way that favors a slight inward pressing motion.
Why the Angled Dumbbells Work Better:
A slight inward angle better follows the natural path of pec fibers during contraction.
It allows for greater adduction of the humerus, which is a primary action of the pecs.
Barbell pressing locks your arms in a fixed, pronated position, limiting your ability to align with the pecs natural line of pull.
Dumbbells allow a more natural arc, improving mechanical advantage and reducing shoulder strain, especially for those with poor shoulder mobility.
Benefits of the Angled Dumbbell Press:
Greater pectoral activation due to better alignment with fiber direction.
Improved range of motion at the bottom of the press.
Reduced joint stress, particularly on the anterior delts and rotator cuff.
Encourages controlled movement and stabilization, which recruits more muscle fibers.
Using dumbbells at a slight inward angle better matches the natural biomechanics of the pec muscles. Instead of pressing straight up and down like with a barbell (which restricts the movement), the angled press follows the arc of humeral adduction, which is how the pecs contract most effectively leading to greater muscle stimulus and hypertrophy potential.
