To trick in this exercise is to try and lift the dumbbells into the starting position without wasting too much energy. Place the dumbbells on the edge of your knees and raise your knee up to your shoulder. This will allow you to get the dumbbell into the starting position quite easy.
With the dumbbells now at shoulder level power them up over your head and lower the weight in a controlled manner at a slower pace. As dumbbells allow for an increased range of motion to the barbell, start with your palms facing each other and rotate your palms forward at the top of the movement. This will allow you to get an extra stretch during the movement utilising your deltoids better. Like the military press do not lock your elbows at the top of the movement. This will keep the tension on your deltoids.
