Make the lateral raise work even better with this simple modification.
Compared to other free-weight lateral raise variations, this exercise puts the deltoid under tension for a greater portion of the range of motion, making each rep more effective. It also places greater overload at the top of the movement.
Think about "pushing the dumbbell away" from your body as you raise it. This keeps your traps from taking over and keeps the tension where you want it.
There are 3 ways to simulate growth: Inflict structural damage, increase neural activation, or prevent blood and oxygen from entering the muscle during a set. Few exercises do all three, but the constant tension alternate curl does.
