Position: Stand, back straight, feet flat on the floor, head neutral/still. Grip always with fingers and thumb around the handle.
Breathing: Exhale when you exert at the start of the exercise and inhale when returning to start position.
Start/Movement/Finish: Alternate each arm. The key is to keep both dumbbells moving. Bend one arm to the top and as soon as it starts down, the other one starts up. Watch for too much backswing, the dumbbell going behind your leg, excessive shoulder swing, speeding up, and not straightening the arms, all of which break down technique.
