SETUP: Use a 90* bench to support your back. Keep your shoulders pinned back and chest puffed out.
LIFT: The rep starts with your dumbbells slightly below a 90* angle. Press the weights up and overhead, bringing them together (not clanging them), then control the weights as you return to the start position.
TIP: Notice we switch from FULL REPS to HALF REPS with this technique, working in the bottom third of the movement with those partial repetitions.
