Dumbbell One Arm Wide-Grip Bench Press
Dumbbell One Arm Wide-Grip Bench Press Exercise Description
The Dumbbell One-Arm Wide-Grip Bench Press is a unilateral chest press performed on a flat bench with the working arm traveling on a wider path (elbow more out to the side). This widens the horizontal shoulder adduction emphasis of the pectoralis major while the anterior deltoid and triceps brachii assist. Using one dumbbell at a time increases anti-rotation demand, so your trunk and scapular stabilizers must keep the torso level and the shoulder centered on the bench. Maintain a neutral spine with the standard five points of contact (head, upper back, glutes, and both feet) and move through a controlled range that does not exceed comfortable shoulder extension. The goal is smooth pressing mechanics: forearm vertical under the dumbbell, wrist neutral, shoulder blades set, and the ribcage quiet as the weight travels above the mid-chest.

How To Do The Dumbbell One Arm Wide-Grip Bench Press Exercise
‘- Lie on a flat bench with feet flat. Establish five-point contact and light scapular retraction/depression.
– Hold one dumbbell with a pronated grip above the mid-chest; wrist neutral and stacked over the elbow.
– Place the free hand lightly on the bench or torso to resist rotation; keep shoulders and hips square.
– Inhale as you lower the dumbbell in a wide arm path, elbow moving out to the side while the forearm stays vertical.
– Stop when the dumbbell reaches chest level (or just above) without the upper arm dropping far below the torso; keep the shoulder centered and ribcage down.
– Exhale as you press the dumbbell up, driving the humerus toward the midline without shrugging; maintain scapular set and a neutral wrist.
– Finish with the arm extended without forcefully locking the elbow; the dumbbell should be over the mid-chest, not the face.
– Keep the torso level throughout—avoid arching excessively, flaring the ribcage, or letting the shoulder roll forward.
– Lower under control to each rep’s start position; when done, bring the dumbbell to your chest, roll to your side, and sit up before switching arms.
Dumbbell One Arm Wide-Grip Bench Press Tips
‘- Establish five-point contact on the bench (head, upper back, glutes, both feet) and maintain a neutral spine.
– Lightly retract and depress your shoulder blades before pressing and keep them “set” throughout the set.
– Start with the dumbbell held over your mid-chest in a pronated grip, wrist neutral and stacked over a vertical forearm.
– Place your free hand lightly on the bench or your torso to resist rotation and keep your shoulders and hips square.
– Keep your torso level and avoid excessive arching or flaring your ribcage as you press.
– Inhale as you lower the dumbbell in a wide path, letting the elbow move out to the side while the forearm stays vertical.
– Stop the descent at chest level or just above, so the upper arm does not drop far below the torso and the shoulder stays centered.
– Exhale as you press, driving the upper arm toward the midline without shrugging and maintaining your scapular set.
– Finish each rep with the arm extended but without forcefully locking the elbow, keeping the dumbbell over your mid-chest, not your face.
– After the final rep, lower under control, bring the dumbbell to your chest, then roll to your side and sit up before switching arms.
Dumbbell One Arm Wide-Grip Bench Press Beginner Introduction
The Dumbbell One-Arm Wide-Grip Bench Press is a single-dumbbell chest movement performed lying on a flat bench. The working arm travels on a broader arc than a traditional press, placing strong emphasis on the chest as the arm moves across the body, with the front shoulders and triceps helping drive the weight. Because only one side is loaded, the midsection, hips, and muscles around the shoulder blades work hard behind the scenes to resist twisting and to hold the torso steady on the bench.
During each repetition, the body stays planted on the bench and floor at five main contact points—head, upper back, hips, and both feet—while the spine rests in a natural, neutral curve. The dumbbell travels in line with the middle of the chest rather than over the face, with the forearm stacked under the weight and the wrist held straight. The movement style highlights smooth, controlled pressing and stable, calm ribcage and shoulder positioning from start to finish.
