This variation to the Dumbbell Bench Press works further into the upper chest and anterior deltoids, but is broadly similar to the traditional Bench Press.
Set your bench up at an angle of 30-45 degrees. Plant your feet into the ground and lie back on the bench. Take your arms wide with your palms facing away from you and your wrists above your elbows.
From here, press both your arms into the air before lowering them back down in control as far as you can go, achieving a stretch across the chest.
At the top of each repetition aim to achieve a straight arm without straining the head or the neck, whilst keeping engagement through the core.
