Dumbbell Straight Arm Pullover (Knees At 90 Degrees)
Dumbbell Straight Arm Pullover (Knees At 90 Degrees) Exercise Description
The dumbbell straight‑arm pullover (knees at 90 degrees) trains controlled shoulder movement through a long lever while encouraging a neutral spine. With a slight, fixed elbow bend, you arc the weight from above the chest to behind the head and back, emphasizing pectoralis major and latissimus dorsi with help from teres major and the long head of the triceps (isometric). Elevating the legs and bending the hips and knees to roughly 90° helps keep the ribcage “down,” minimizes lumbar extension, and promotes better trunk bracing. The movement also challenges the serratus anterior and scapular stabilizers to keep the shoulder complex centered as the arms travel overhead. It’s a slow, controlled pattern that builds shoulder mobility under load and reinforces precise rib‑pelvis alignment without turning the exercise into a triceps extension.

How To Do The Dumbbell Straight Arm Pullover (Knees At 90 Degrees) Exercise
‘- Lie supine on a stable surface (e.g., flat bench). Bend hips and knees to about 90°, shins parallel to the floor; maintain a neutral pelvis and spine.
– Hold one dumbbell vertically with both hands on the inner plate/handle end; wrists neutral and stacked.
– Start with arms straight above the mid‑chest, elbows softly bent ~10–20° and kept fixed throughout.
– Set the shoulder blades gently “down and back” without shrugging; keep ribs quiet.
– Inhale, brace, and lower the dumbbell in a smooth arc behind the head by moving at the shoulders. Allow natural scapular motion, but avoid forward shoulder glide.
– Stop when you feel a controlled stretch (upper arms near line with torso) or before ribs flare or low back arches.
– Exhale and pull the arms back over the chest by driving through the chest and lats; keep elbow angle unchanged and wrists neutral.
– Keep head and neck relaxed, eyes up; do not thrust the chin or press the low back off the surface.
– Return to the start position under control, pause, and maintain the 90° knee/hip position throughout.
Dumbbell Straight Arm Pullover (Knees At 90 Degrees) Tips
‘- Keep hips and knees bent to about 90° with shins parallel to the floor to help maintain a neutral pelvis and spine.
– Hold the dumbbell vertically by the inner plate/handle with wrists neutral and stacked, and keep this hand position consistent.
– Start with arms straight above the mid‑chest, not the face, with elbows softly bent about 10–20° and fixed in that position.
– Gently set the shoulder blades “down and back” without shrugging, and keep the ribs quiet as you move.
– Lower the dumbbell in a smooth arc behind the head by moving at the shoulders only, without changing the elbow angle.
– Allow natural scapular motion on the way down, but avoid letting the shoulders glide forward.
– Stop the descent when you feel a controlled stretch or as soon as the ribs begin to flare or the low back starts to arch.
– Pull the arms back over the chest by driving through the chest and lats while keeping the elbows fixed and wrists neutral.
– Keep your head and neck relaxed with eyes up, avoiding chin thrusting or pressing the low back off the surface, and maintain the 90° hip/knee position throughout.
Dumbbell Straight Arm Pullover (Knees At 90 Degrees) Beginner Introduction
The dumbbell straight‑arm pullover (knees at 90 degrees) combines upper‑body strengthening with strong midsection control. It is performed lying on a bench or similar surface while holding a single dumbbell with both hands and moving the arms in a smooth arc overhead and back. Because the elbows stay slightly bent and fixed, the effort centers on the chest and lats, with the backs of the upper arms working mainly to stabilize rather than bend and straighten. Muscles around the shoulder blades and along the ribcage also stay active to guide the shoulders as the weight travels behind the head.
Leg position is a key feature here. With the hips and knees bent to form right angles and the shins up, the lower back is less likely to overarch and the ribcage stays more naturally stacked over the pelvis. This creates a strong sensation of bracing through the core while the shoulders move through a large, controlled range, building strength and mobility without turning the motion into a triceps‑focused exercise.
