Dumbbell Prone Alternate Hammer Curl
Dumbbell Prone Alternate Hammer Curl Exercise Description
The dumbbell prone alternate hammer curl is a chest-supported elbow-flexion exercise that emphasizes the forearms (brachioradialis) while also training the brachialis and biceps brachii. Performing it prone on an incline bench minimizes torso sway and reduces shoulder involvement, helping you focus on strict curling mechanics and equal left–right control. The neutral (hammer) grip keeps the forearm in a neutral position throughout, which increases demand on the brachioradialis and brachialis compared with a supinated curl. Alternating arms allows you to maintain consistent trunk position and monitor elbow path on each side. Expect a controlled range of motion from a fully extended elbow to a strong flexed position without shoulder elevation or wrist movement, promoting clean, repeatable reps.

How To Do The Dumbbell Prone Alternate Hammer Curl Exercise
‘- Set an incline bench to about 30–45°. Lie prone with chest supported, feet on the floor, and head in neutral alignment.
– Hold a dumbbell in each hand with a neutral (palms-facing) grip. Let your arms hang straight under the shoulders.
– Set your shoulders: lightly retract and depress the scapulae; keep the ribcage and hips anchored to the bench.
– Brace gently. Keep wrists straight and elbows close to your sides throughout.
– Curl one dumbbell by flexing the elbow only. Do not supinate; keep the hammer grip.
– Lift until the forearm approaches vertical or you feel the biceps/forearms fully engaged without the shoulder rolling forward.
– Pause briefly, then lower under control to full elbow extension without locking or shrugging.
– Alternate sides, maintaining the same range of motion and tempo. Keep the bench contact, neck neutral, and avoid swinging or arching.
Dumbbell Prone Alternate Hammer Curl Tips
‘- Set the bench between 30–45° so your chest can rest fully supported.
– Let your arms hang straight down under your shoulders before you start curling.
– Lightly retract and depress your shoulder blades to keep the ribcage and hips anchored to the bench.
– Use a neutral (palms-facing) grip and keep your wrists straight throughout each rep.
– Keep your elbows close to your sides and flex only at the elbow when you curl.
– Do not supinate; maintain the hammer grip as you lift and lower the dumbbell.
– Curl until your forearm is near vertical or you feel full biceps/forearm engagement without your shoulder rolling forward.
– Pause briefly at the top, then lower under control to full elbow extension without locking or shrugging.
– Alternate arms while keeping the same range of motion and tempo on both sides.
– Maintain chest and hip contact with the bench, neck neutral, and avoid swinging or arching as you curl.
Dumbbell Prone Alternate Hammer Curl Beginner Introduction
The dumbbell prone alternate hammer curl introduces a chest-supported way to challenge the arms with dumbbells while torso movement stays quiet. Lying face-down on an angled bench places the chest against the pad, so the shoulders and trunk contribute less, and attention goes mainly to bending and straightening at the elbow. This setup highlights the forearms and biceps, especially with the palms facing each other throughout the motion.
Each arm works in turn rather than together, encouraging even effort from left and right sides and making it easier to notice how each elbow travels through space. The range of motion moves from a long, straight arm position up to a strong squeeze, then back again in a smooth, steady path. Because the shoulders stay down and the wrists remain firm, the movement pattern emphasizes clean, repeatable curls that rely on the elbow joint rather than swinging or arching through the body.
