Machine Press (Shoulders)
Using the machine takes away the need to stabilise during the movement, focussing the work right on the shoulder muscles. Push the handles up, keeping the elbows out to the sides. Squeeze when you get to the top, come gently back. The machine in our video uses a bar directly over the middle shoulders, working the middle delt. An angle where you're pushing forward would shift the emphasis on to the front delt.
