SETUP: Use an upright bench, and load two dumbbells at shoulder level with your palms facing you.
START: Move the dumbbells outside your shoulders, rotating your wrists as you do, then press the dumbbells straight up.
FINISH: Reverse the process as you lower the weights.
TIP: The main difference between this and an Arnold Press is that we have broken down the rep into two stages here. This means the reps will take about a second longer on this exercise, which increases the time under tension for your shoulders – that’s a good thing! Don’t rush ’em.
