Dumbbell

Setup
Lie on a flat bench with your feet firmly on the floor. Hold a dumbbell in each hand with a neutral grip, palms facing each other. Extend your arms directly above your chest, with a slight bend in your elbows.
How to perform
- Keeping the slight bend in your elbows, slowly lower the dumbbells out to your sides in a wide arc.
- Continue lowering until you feel a comfortable stretch in your chest muscles.
- Reverse the motion, squeezing your chest muscles to bring the dumbbells back to the starting position over your chest.
Form cues
- Maintain a slight, constant bend in your elbows throughout the movement.
- Imagine you are hugging a large tree.
- Keep your shoulders down and back on the bench.
- Control the weight on the way down and on the way up.
Common mistakes
- Bending the elbows too much, turning the movement into a press.
- Lowering the weights too far, placing excessive stress on the shoulder joint.
- Arching the lower back off the bench.
- Using momentum to lift the weights.
