How to do the standing palm-in one-arm dumbbell press
- Start by having a dumbbell in one hand with your arm fully extended to the side using a neutral grip. Use your other arm to hold on to an incline bench to keep your balance.
- Your feet should be shoulder width apart from each other. Now slowly lift the dumbbell up until you create a 90 degree angle with your arm. Note: Your forearm should be perpendicular to the floor. Continue to maintain a neutral grip throughout the entire exercise.
- Slowly lift the dumbbell up until your arm is fully extended. This the starting position.
- While inhaling lower the weight down until your arm is at a 90 degree angle again.
- Feel the contraction for a second and then lift the weight back up towards the starting position while exhaling. Remember to hold on to the incline bench and keep your feet positioned to keep balance during the exercise.
- Repeat for the recommended amount of repetitions.
- Switch arms and repeat the exercise.
Muscles worked
The prime movers are the deltoids, which raise and rotate the upper arm at the shoulder joint.
Because more than one joint is moving, the work does not stay in one place: the triceps straighten the elbow to finish the movement.
How this movement works
The working muscles shorten as they drive the load away from you, and more than one joint changes angle to do it. Load spreads down a chain instead of sitting on one muscle, which is why a compound push handles more weight than any single-joint alternative — and why joint position, not the muscle, is usually what fails first.
It is filed under strength: produce force against resistance for a countable number of repetitions, and progress the resistance over time.
What you need
Dumbbells let each side work on its own, surfacing a strength difference between limbs that a barbell would quietly cover for, and leaving the wrist free to rotate through the movement.
