Description
A strength exercise that targets the shoulder muscles. The exercise is performed by sitting on a bench, holding a dumbbell in one hand, and rotating the arm from a neutral position to a perpendicular position.
How to Do Dumbbell Seated One Arm Rotate
- 1Setup
Sit on a bench with your feet flat on the floor, holding a dumbbell in one hand with a neutral grip (palm facing your body).
- 2Setup
Rest your working forearm on your thigh, just above the knee, ensuring your wrist extends past your knee and can move freely; your palm should face upwards.
- 3
Slowly lower the dumbbell by allowing your wrist to extend downwards, feeling a stretch in your forearm flexors while inhaling during this controlled descent.
- 4
Contract your wrist flexors to rotate the dumbbell back up, supinating your wrist to return to the starting palm-up position, exhaling as you lift.
- 5
Perform the movement with a controlled tempo, focusing solely on wrist rotation and avoiding momentum from your arm or shoulder.
Tips
- Ensure your forearm remains stable on your thigh throughout the exercise to isolate the wrist flexors effectively.
- Control the eccentric (lowering) phase of the movement, taking 2-3 seconds to lower the dumbbell to maximize muscle engagement.
- Use a lighter weight initially to master the form and achieve a full range of motion without straining your wrist.
- Focus on squeezing your wrist flexors at the top of the movement for a peak contraction before slowly lowering the weight.
Common Mistakes
- ×Using momentum from the arm or shoulder instead of isolating the wrist: Ensure your forearm stays firmly planted on your thigh, allowing only your wrist to move.
- ×Not achieving a full range of motion, short-changing the stretch or contraction: Lower the dumbbell as far as comfortable to feel a stretch, then rotate it fully upwards to engage the flexors completely.
- ×Gripping the dumbbell too tightly, which can fatigue the forearm unnecessarily: Maintain a firm but not crushing grip to allow for fluid wrist rotation.
